Is There Intelligent Life Out There?

One of our previous articles discussed the minerals of Star Trek, giving rise to the hope that there is extraterrestrial life out there, but the honest discussion about ET’s existence is a loaded subject. 

For this article, we are going to focus on the probability of whether life exists in outer space; in other words, what are the odds that there really is intelligent life on other planets?

As difficult as it is to wrap our heads around the sun’s fusion process, which is equivalent to 100 billion atomic bombs per second, we will go one step further and try to understand the immense size of our universe, and then look at the formulas that scientists have developed to determine ET’s existence.

2023 Update on Extraterrestrial Life

It was already known that one of Saturn’s moons – Enceladus has oceans, but its Cassini spacecraft just recently found that its oceans contain the element phosphorus, which is a key chemical element in the building blocks of life.

This brings us one step closer to finding out if life exists right in our own backyard.

But what about intelligent life?

So What Are the Odds?

It is estimated that there is an average of 1 – 2 billion stars in any recorded galaxy and there are over 2 trillion galaxies out there. If 10% of each galaxy contains a solar system, that is, it contains a star that has planets revolving around it, then we can estimate that each galaxy has between 100 – 200 million solar systems, with some that may be fairly similar to ours.

If 1% of the stars in each solar system have a planet just distant enough from their sun where life could evolve, called the habitable zone or as some scientists call it, the Goldilocks Zone, we could have 1 – 2 million possible planets that could contain life.

Going further, if 1% of these planets have the right ‘ingredients’ to build intelligent life, then there is the possibility that there may exist 10,000 stars that could have planets with intelligent life in each galaxy.

Just to be more realistic, we can cut the odds even further and take 10% of this result, which would equate to the possibility of 1,000 stars with extraterrestrial life in each galaxy.

That would mean that there could be 1,000 x 2 trillion galaxies = 2,000,000,000,000,000 (2 quadrillion) planets with intelligent life. How many is that? Just take a look at this numerical comparison; thus, If we use the estimate of two trillion galaxies in the universe, that would mean ET may live on over 2 quadrillion planets in our universe.

Don’t even try to comprehend how many fusion reactions occur here every second when you include all of these stars. Fuhgeddaboudit!

What About the Scientific Formulas?

The above calculations were based on a general layman’s assumption, but have the experts given the possibility of extraterrestrial life serious thought?

American astronomer and astrophysicist Dr. Frank Drake developed a formula that he presented at a meeting in Virginia in 1961. It is called the Drake Equation, which calculates the possibilities of life on other worlds within our own Milky Way galaxy.

We won’t go into the calculations, but in a general sense, it is based on our assumptions above but uses trigonometry to formulate a much more explicit and precise determination of ET’s existence. For you science and math connoisseurs, feel free to give it a shot below!

The terms are as follows:

N : The number of planets in the galaxy where electromagnetic emissions are detectable
R: The rate of scanability to have exoplanets with habitable Fnes revolve around them
fp : The fr those stars that have solar systems
ne : The number of planets in each solar system within the Goldilocks Zone
f:r of planets on where life may exist
fi : The number of planets where intelligent life may exist
fc : The number of planets that have civilizations with a technology where we can detect their signals
L : The length of time that these civilizations have produced these signals

What About the UFO Sightings?

Now we come to the discussion of UFOs. If life does indeed exist, are they here or not?

Where are the Pictures?

Dr. Neil deGrasse Tyson, astrophysicist and Director of the NYC Hayden Planetarium at the Rose Center for Earth and Space had an interesting thought.

He said with all the cell phones that people have these days (which account for hundreds of millions), not one person has come forward with a clear picture of a UFO, alluding to the assumption that if there is life in outer space, they most likely have not reached us.

We are sure Dr. Tyson believes that intelligent life does exist, but he is being realistic in suggesting that ET still has to come here before he calls home.

What About Worm Holes?

Dr. Tyson’s view is the opinion of one expert and his statement is by no means conclusive. With that said, Dr. Tyson welcomes the opinions of other experts in the field, such as his colleague theoretical physicist and CUNY Professor Dr. Michio Kaku, who advances to theories beyond current reality and states that aliens could be here by way of quantum computing. (To see the complete discussion of Dr. Tyson and Dr. Kaku, check out our article on quantum computing).

The Quantum Link

We earthlings are only at the fetal stages of quantum computing, but Dr. Kaku suggests that it’s quite possible that extraterrestrial life has already harnessed quantum computing and in so doing, they have been able to obtain the answer to many questions that have baffled humans for mellimena. One such question would be is – how did the big bang happen?

Moreover, if they are able to tackle that question, there is no doubt that they also have been able to determine how a wormhole operates. A wormhole is a phonenoma that allows one to travel from one end of the galaxy to the other or event from one galaxy to another in a matter of minutes.

If this is the case, then perhaps ET is already here and with their advanced capabilities, they could easily cloak themselves from the vision of us Earthlings and if Dr. Kaku’s theories are correct, maybe, just maybe the suggestions of aliens in Men in Black are right!

Conclusion

It is mostly a unanimous decision by scientists that extraterrestrial life does exist and there is agreement that there also is intelligent life out there somewhere, so the question is are they here on Earth or not? And that is where there are still open discussions.

But regardless if they are here, would they look like us? If not what would they look like? Another interesting dilemma to consider!

The Goldilocks Zone – Just Right!

Solar System Planets

Remember learning about our solar system in elementary school? Our teacher gave us this verse: “Mary’s Violet Eyes Makes John Stay Up Nights. Period”. Well, as we all know now, the “Period” which represents Pluto is no longer a planet. It was reduced to a dwarf planet and not considered to be large enough to be part of our planetary solar system anymore. So we are left with Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

Which Planets in Our Solar System Have an Atmosphere?

All of them except Mercury. It is just too close to the sun to sustain one. But if Mercury is the only planet not to have an atmosphere and thus, not allow life as we know it to thrive, why is there no life on the other planets aside from Earth? 

The Goldilocks Phenomenon 

Scientists call it the Goldilocks Theory. We like to call it something a bit more sophisticated – The Goldilocks Phenomenon, but any way you look at it, we are alive today because the atmosphere above us is the partridge that is just right! 

The Five Atmospheric Layers

If you draw a line from the first layer (the troposphere) to the last layer (the exosphere), it would be approximately 62 miles in length. As we work our way up through the layers, they each get thinner until they (the atmospheric gasses) dissipate). 

The line is called the Kármán line and is the accepted standard where scientists say the atmosphere meets space, but it is not a strict designation, as it is hard to say exactly where the gasses dissipate completely into outer space. There are so many factors to consider, the temperature being one of the main disparities since this component may differ within different parts of the earth.

With this in mind, let us define the five layers: troposphere, stratosphere, mesosphere, thermosphere, and exosphere.

Graphic of the 5 atmospheric layersThe Troposphere

Ever realize that when you go into an airplane, it gets colder as you go higher? Air is warmer near the ground and gets colder higher up. Nearly all of the water vapor and dust in the atmosphere are in this layer and that is where clouds are found here. It contains about 99% of the water vapor, called condensation within the earth’s entire atmosphere and consequently, this is where all of the weather conditions materialize. So it might not be much of a surprise that the troposphere contains about 80% of the total mass of the entire atmosphere.

The Stratosphere

This is probably the best known layer as we frequently hear about NASA’s spacecrafts  “reaching the Stratosphere”. It is also where most of our jet aircraft fly. This layer extends about 31 miles above the ground, so if the troposphere runs approximately six miles high, the stratosphere picks up at the six/seven-mile marker.  

Another common term we hear a lot is the ozone layer. Well, it’s the stratosphere that contains this sub-layer which acts as a natural atmospheric shield by absorbing harmful radiation from the sun. 

Due to man-made pollution, a gap in the ozone layer developed. It extended 6.3 million square miles at one point, but there are positive signs that this hole is naturally healing itself and is the smallest it has ever been at this time.

The Mesosphere

In one of our recent articles on deep mining, we spoke about temperatures reaching as high as 145° degrees. Now we go to an area you wouldn’t want to venture to either, but this time the temperatures go in the opposite direction; that is, way low to about −225°.  Now that’s cold and is the average temperature in this layer. Ironically though, it is also the layer where meteors burn up when entering the earth’s atmosphere.

Any water in this layer here freezes into ice clouds. They make for some beautiful colored skies. The scientific name for them is noctilucent clouds, also called polar mesospheric clouds (not to be confused with the northern lights, which are different). These mostly blue-like clouds are visible at sunset from each of the earth’s poles.

The Thermosphere 

This layer extends between 310 and 620 miles and temperatures can get up to 2,700 degrees. The International Space Station orbits here and this is the layer where we do see the northern lights, also called the Aurora Borealis and Aurora Australis.

The Exosphere

We have reached the final destination. The air is extremely thin here, but unless you are excited with an abundance of hydrogen and helium, just be content to know that the end of the exosphere is where outer space begins.

Conclusion 

What’s your favorite layer? Before you answer, the best bet is to take a ride up there. The next flight to the International Space Station is set for October 22, 2020. Register early. We hear that the bookings are filling up fast! 

 

How Planets and Stars Compare

Why is it that you can’t look at the sun for more than 1/2 second? What would happen to you? No doubt you will need a trip to the optometrist or worse, you may go blind!

So, what is it that causes this object that is 93 million miles from Earth so powerful? Simply speaking, the sun is a star, and just like any star, they are extremely large in comparison to planets and carry the equivalent of millions of atomic bombs that ‘explode’ every second.

Learning how planet sizes compare to each other, then how the different stars compare to each other is a worthwhile journey and one that fascinates many. Once you read this article, you may find it inconceivable to try to comprehend the size of our universe. In one word – Mind-boggling.

Comparing Our Planets to Each Other

Planets are a mere spec in our galaxy.  In the first illustration below, we compare the eight planets in our solar system. From the left, we have Saturn and Jupiter. Middle, we have Uranus and Neptune. The front row is Mercury, Venus, Mars, and Earth. Note how Jupiter can engulf Earth by about 50 times.

In our next image, we move closer inward and look at the inner solar system. There is an error in the image below. Can you find it?

Pluto does not belong here for two reasons. (1) It is not part of the inner solar system and (2) it is not considered a planet anymore.

Comparing the Sun to the Planets

This image shows the planets compared to our sun. The Earth here is now hardly visible. Even Jupiter is the size of a pea compared to the sun. If the sun was a basketball, then Jupiter would be a pea.

Think the sun is big! Think again. The image below compares the sun to the star giant Arcturus, which is 37.5 light-years from Earth and is larger than the entire orbit of Mercury. Read more about Arcturus here. Another basketball to pea scenario.

Comparing Other Stars to Each Other

If these sizes don’t fascinate you, take a look at the next illustration, showing Arcturus paired with the star giants Betelgeuse and Antares. Forget about trying to see any of our planets here, as the sun is a mere pixel on the screen. That would equate to a grain of sand against a basketball (Antares). See our summary below.

We hope these comparisons give you a better appreciation and respect for the galaxy and the universe.

Summary:

We started with a comparison of Earth to the four inner planets in the solar system. Earth appears the largest. Then Earth and the inner four planets are compared to the outer planets and Earth now appears like a pea to a basketball (Jupiter).

Next, all the planets in our solar system are compared to our Sun, a medium-sized star in the Milky Way galaxy. Continuing to use the pea as our example as Earth and the basketball as Jupiter, the sun would be the size of a 10-story building. Putting a pea and a basketball next to this building, well you can start to appreciate the immense sizes of the objects in space, but we haven’t even scratched the surface yet.

The image below is an estimated comparison between planet Mars’s orbit superimposed on the giant star Antares. Notice how Antares engulfs its orbit with room to spare. Earth would not be visible here, nor would Jupiter.

One could only imagine the immense gravitational pull this star would have on any objects coming close to it. Future black hole?

Well, we don’t stop here. The largest known star is UY Scuti, located in the constellation Scutum, it is 1700 times larger than the Sun.

With stars this big, one can only imagine the great gravitational pull they will have on other objects in their neighborhood, and in so doing, we can begin to understand how black holes can be formed.

There is also a fascinating website called Scale of the Universe which will help you look at the ‘big picture’, pun intended.

March 2015 – R131 in the Large Magellanic Cloud was recently found to be the largest star to date.

What is Gravity?

It’s invisible. You can’t smell it. You can’t taste it, but if you fall off a tree you will definitely feel its presence. It is gravity. One of the mysteries of the universe that keeps us together, literally.

Explanation

Simply put, gravity is an entity that draws objects inward and when this happens, interesting things occur. All planets’ moons rotate around their planet due to their gravitational pull. Planets rotate around their stars, because of the star’s gravitational pull, and stars rotate around their galaxy’s black hole, which has a mind-boggling gravitational force within it.

How Gravity is Formed

Nebulas contain random masses of gas and dust. When this gas and dust start combining, gravity begins to build, which then attracts more matter to combine with the building of gas and dust. Subsequently, the mass can become so big that planets can be formed and if the forming mass gets larger, stars will be created. And onward it goes, (over billions of years), eventually entire solar systems are created, all due to the mysterious force of gravity.

Our moon has gravity as well, but since it is much smaller than Earth, it only has a minimal effect on our planet. The oceans feel the moon’s gravitational pull, which is why we see tides moving in and out.

The Moon’s Influence of Title Waves on Earth

In summary, the more massive the object is the more mass it has and the stronger its gravitational pull will be, so gravity is proportional to mass. In addition, the closer an object is to another object, the stronger its gravitational pull will be on that object as well.

 

Black Holes – The Mystery of Outer Space

Ever wonder what a black hole is? If I told you that you would be stretched like a rubber band if you came near it, would have I captured your interest?

From planets that orbit around the Sun to galaxies that are bounded by a special force (gravity), the universe is full of surprises and one such surprise is the black hole. These entities have such a high gravitational pull that not even light can escape, which is quite fascinating and mind-boggling in itself. 

The existence of black holes was first predicted by Albert Einstein, but the term wasn’t coined with that name until many years later. Initially considered a theoretical object, the first physical black hole was discovered in 1971, but the first-ever image of a black hole was released only this year, which has opened up a new area of study on these magnificent entities. Researchers and astronomers now know what a black hole looks like. But for us, it is important to understand what it is.

First-ever image of a black hole. 53 million light-years from here in the M87 galaxy. Scientists used the Event Horizon Telescope (EHT) which are scores of telescope arrays located in different parts of the world and synchronized to focus on the object on the same day and at the same time.

What Exactly is a Black Hole?

Before we begin, we need to identify two entities. One is matter. The other is gravity. We all know what gravity is, so let’s focus on matter, which is nothing more than an object that is made up of atoms. From the tiniest microorganisms to the largest stars, all objects are made up of matter.

The next factor to note is that all matter has gravity, which is proportional to its size, the larger the object is, the more gravity it will have (we are talking about objects that exist in space, not on Earth).

One example is our planet Earth, which weighs about 13,170,000,000,000,000,000,000,000 pounds (or 5,974,000,000,000,000,000,000,000 kilograms or 5.972 × 10^24 kg ). Yes, that’s a lot but when referring to the size of the universe, it is analogous to a grain of sand on a beach. Its weight (or the amount of matter it contains) is sufficient to have enough gravitational pull to hold the moon in its orbit and revolve around it.   

On a grander scale is our Sun, whose gravitational pull keeps the Earth and the other seven planets to revolve around it. If the Sun had no gravity, the Earth (and every other body in our solar system) would be endlessly floating through the universe. 

When stars die, they collapse within each other. When our Sun dies, which is expected to happen in about 4.5 billion years, it would collapse into itself, because gravity would be pulling all its mass towards its center. The remains would be a piece of matter about the size of Earth, called a white dwarf.

Since the Sun doesn’t have a sufficient amount of matter/gravity to collapse into itself any further, it will remain as a white dwarf. Another way of describing a white drawf is that its mass may be equal to that of the Sun, but its volume is comparable to that of Earth. This type of event is very common and consists of about 97% of the stars in our Milky Way galaxy.

 

But What About Larger Stars?

Just think of a star that is massive enough to have such a strong amount of gravity that all its matter gets pulled into the point that it is so much smaller than the Earth-size we mentioned before. As a general reference, let’s say about 18 miles in diameter.

In other words, it is packed so greatly that even though the result is a smaller object, it becomes more dense, because all that matter is condensed within a smaller volume. When this happens, it is called a supernova and results in what astronomers call a neutron star.

You Still Didn’t Explain How a Black Hole is Formed?

Those stars previously mentioned do not have sufficient mass to collapse to the point that they produce a black hole. Now, for stars that are that big, 

A black hole is an area in outer space with an exceptionally high gravitational pull. So far, we have predicted the force exerted by the black hole. But it is so strong that even light cannot escape if it goes close to a black hole. 

Scientists, however, have understood the reason for such a high gravitational pull. It is because matter has been crammed into a very tiny place. When very huge stars die, they form black holes that continue to absorb all the mass in the surrounding vicinity. Scientists also believe that at times, a single hole can merge with other nearby black holes. It is also hypothesized that the center of any galaxy in outer space is a huge black hole. 

Since light cannot escape, we cannot see black holes. They are invisible, but their presence can be felt. NASA has managed to develop special space telescopes that can help locate black holes. These special telescopes can also observe how stars close to black holes behave differently compared to other stars. 

Black holes can vary in size. A small black hole can be as small as a single atom, but it can have a mass equivalent to a mountain. So regardless of the size, what makes black holes unique is the mass of matter that is squeezed into them. 

Types of Black Holes

Astronomers and researchers have categorized black holes into four types.

Supermassive Black Holes 

Artist Conception of a Supermassive Black Hole

The first type of black hole is also the largest. This type of black hole has an immeasurable amount of mass. Scientists believe that supermassive black holes are present at the center of galaxies in space. This type of black hole is also found in our solar system and is located at Sagittarius A*. 

Intermediate Mass Black Holes

So far, this is a hypothetical type of black hole. The mass in these black holes can range from 100 to 10 hundred thousand solar masses. There is no proof of the existence of this type of black hole. However, there is indirect evidence of the existence of such black holes due to the behavior of certain stars. 

Stellar Black Holes 

This type of black hole is formed when giant stars collapse. The mass of such black holes ranges from 5 to 100 solar masses. This can be observed as a hypernova explosion or a burst of gamma-ray. This type of black hole is also called collapsars. 

Mini Black Holes 

This is the last type of black hole. As the name suggests, they are small black holes with less than 5 solar masses. Mini black holes were introduced by Stephen Hawkings in 1971.

Major Black Holes Near Our Galaxy 

So far, researchers have spotted three major black holes near our galaxy. 

A0620-00

Scientists believe that A0620-00 is a stellar black hole, which is approximately three thousand lightyears away from the Earth. This system of a collapsing binary star belongs to the Monoceros constellation. It comprises an unidentified quantity of solar mass and a star. 

Cygnus X-1

Found in the constellation of Cygnus, this black hole was discovered in 1964. This is one of the few black holes which are widely accepted by scientists around the world. It is estimated that this black hole has 15 solar masses and is about 5 million years old. Scientists also believe that it comes from a star that was originally more than 40 solar masses. 

V404 Cygni

V404 Cygni is also categorized as a stellar black hole equivalent to 12 solar masses. It also has a star. The star and the black hole orbit within a close range. Because of the proximity of the star to the black hole and the intense gravitational pull, this star continues to lose mass to the black hole. 

Beyond Black Holes

There is nothing more mystifying in outer space than black holes. So far, we only know that as we get closer to the edge of the black hole, nothing returns. The gravitational pull is so high that it attracts even the tiniest particles of light. However, we also know that the force is different from suction. So just like something falls on the ground due to gravity, it moves into the black hole due to the same pull. 

It is believed that pressure and temperature inside the black holes can be so extreme that it does not support any form of organic life as we know it. Considering life forms that are not organic, we can definitely not comment on that now. No one knows for sure what lies inside the black holes. On one end, there is a galaxy, but what lies on the other side still remains a mystery.
