THE TRUTH ABOUT FLYING SAUCERS: Part 3 Why Are There No Aliens on Planet Earth?

Today, the case for why there are no aliens on Planet Earth, now, or ever in the past.  But first, global beliefs regarding aliens:

Then there is the Fermi Paradox.

• In the summer of 1950, Enrico Fermi, who had won the 1938 Nobel Peace Prize, had lunch at Los Alamos with three colleagues, Edward Teller (father of the Hydrogen Bomb), Emil Konopinski (calculated that this H-bomb would not ignite the Earth's atmosphere) and Herbert York (became director of the Lawrence Livermore National Laboratory).

• 
  Edward Teller recalls "in the middle of the conversation, Fermi came out with the quite unexpected question 'Where is everybody?'…The result of his question was general laughter because of the strange fact that in spite of Fermi's question coming out of the clear blue, everybody around the table seemed to understand at once that he was talking about extraterrestrial life".

• 
  In his account of the famed luncheon, Teller wrote "I do not believe much came from this conversation, except perhaps a statement that the distances to the next location of living beings may be very great and that, indeed, as far as our galaxy is concerned, we are living somewhere in the sticks, far removed from the metropolitan area of the galactic center".
• York recalled a somewhat more expansive discussion in which Fermi "followed up with a series of calculations on the probability of earthlike planets, the probability of life given an earth, the probability of humans given life, the likely rise and duration of high technology, and so on. He concluded on the basis of these calculations that we ought to have been visited long ago and many times over".

• 
  According to York, Fermi supposed the reason we hadn't been visited "might be the interstellar flight is impossible, or if it is possible, always judged not worth the effort, or technological civilization doesn't last long enough for it to happen".

So there is a layered series of questions;

• Is there life somewhere in the universe?
• Have aliens visited Planet Earth?
• Is it possible to travel long interstellar distances?

Three years ago, another of my UFO postings said:  From SciTechDaily:

The closest star to Earth is Proxima Centauri. It is about 4.25 light-years away, or about 25 trillion miles (40 trillion km). The fastest ever spacecraft, the now-in-space Parker Solar Probe, will reach a top speed of 450,000 mph. It would take just 20 seconds to go from Los Angeles to New York City at that speed, but it would take the solar probe about 6,633 years to reach Earth’s nearest neighboring solar system.  How much energy will it take for an actual flying saucer at that size getting here from light years away?  Keep in mind that the closest (there are a lot of dwarf ones closer) galaxy to our Milky Way is more than 2 million light years away, so that same object mentioned above would take 35 billion times longer.  There are something like 2 trillion galaxies out there, and furthest is 13.5 billion light years away.  We live in large universe.  Thus, the best options for interstellar travel are things physicists can only dream about, beyond anything we know, but not impossible.  Essentially, we need to go faster than the speed of light using almost no energy.

  Passing through worm holes.
• A wormhole conceived by Albert Einstein and Nathan Rosen allows movement from one place to another by passing into an extra dimension of space.

• 
  Say you want to explain a worm hole in space to a 7-year old.  From Quora.  Print out a map of the USA. Say space is like driving from Los Angeles to Jacksonville. Show them your finger going from Los Angeles to Jacksonville. Then, fold the paper so that Los Angeles and Jacksonville are next to each other, and take a pencil and make a hole through the paper connecting the two cities. Explain that, using that hole, you can get between the two cities instantly. Tell them this is how a wormhole works.
• 
  Physicists have created a holographic wormhole using a quantum computer.  The team was led by Maria Spiropulu of Caltech.
• Remember time machines from movies?  Well, this same wormhole can theoretically send you back in time.  Can you imagine restarting time?  All of this is beyond my ken.

• 
  Using warp drive.  
• Sort of compressing space and time.  
• One problem is that you need negative energy and or mass.  

• 
  But we know nothing much about dark energy and dark mass, so who knows.  
• In 1994 Miquel Alcubierre first propose his Alcubierre Drive.
• And some researchers are hopeful.  Read this paper.  Or this one.

I just stumbled across yet another article showing why the odds are very, very low for aliens ever having being on Planet Earth. Some excerpts of this discussion.

To begin with, space is vast – beyond our imagination. 

• Proxima Centauri, the nearest star to our Sun, is about 40 trillion kilometres away, 268,000 times farther than the Sun is from Earth. That’s 4.3 light years as astronomers measure it. A light year is the distance light travels in one year at 300,000km per second. 

  We can only travel across space at a fraction of the speed of light with current technology. Even our fastest spacecraft, the Parker Solar Probe, travels at a top speed of roughly 191 kilometres per second – 0.064% the speed of light.  At that speed, it would take about 6,650 years to reach Proxima Centauri, and that’s just in our local stellar neighbourhood. So interstellar travel within human lifespans would require much higher velocities.

• Then there’s the unimaginably high energy requirement for interstellar travel. The mass of the spaceship increases with velocity, so an increasing amount of energy is required to accelerate it.  At the speed of light, the ship becomes infinitely massive, requiring an infinite amount of energy. This is clearly impossible.

  A video on the Feynman Reality Check.

If that publication doesn't convince you about the impossibility of long distance interstellar travel, here is another, from MIT that should.

Mind you, as I've postulated several times in this blog site:

• The vast numbers of potential sites for life, then intelligence, convince me that someday there will be contact made.  Here is a quick summary of what I did at the NASA Ames Research Center in SETI.

• 
  Pioneers are speculating on how best to reach out into space, like Breakthrough Starshot.
• But humans are not made for space travel.  Watch this video.  And another.  That was two hours long.  Here is another video of only 30 minutes.

• 
  If Artificial Intelligence someday evolves as the next form of superior intelligence on Earth, this form of "life" would better be able to travel to extrasolar planets and survive.

• 
  Our universe is only 13.8 billion years old.  
• Our Sun will expand in 5 billion years, so if we are the only intelligent life in the universe, the only way to continue "our" existence will be to escape.  
• After all, there are models showing that our universe will be around for hundreds of trillion years longer, and maybe even 10 to 120th power years as an extreme.

Finally, Kilauea Volcano erupted into Episode 55.  There is a long story here, going back September 10 when we were on the Silver Whisper, docked in Hilo, Hawaii.

• I said:  IN OTHER WORDS, IT LOOKS LIKE KILAUEA WILL ERUPT TODAY!!! There is a good chance that a tour from the Silver Whisper will get to see fountains of lava.
• So I was wrong by 35 days.  Watch this video.
