Are We Alone?

Just the Milky Way galaxy

Haven’t we all wondered at one time or another . . . are we alone?  Yes, you may very well be alone while reading this blog and hopefully you were alone when you went to the bathroom this morning, but the graphic gives us the real intent of the question: Are we the only people in the universe, in all of space?

If we include ‘all of space’, first we don’t even have a clue as to how big ‘all of space’ is, but what we do know is that just in our Milky Way galaxy, there are trillions of planets with many of them orbiting stars just like our sun.  And if you consider space beyond our galaxy, the odds are pretty good that there is intelligent life out there somewhere; and to complicate matters in our search for intelligent life, lately we’re not even sure we can find intelligent life here on Earth!

A comment from famous American-Italian and Manhattan Project physicist, Enrico Fermi, is one of my favorites when contemplating the mystery of intelligent life ‘out there’..  After hearing how vast space is and the probable odds of having life out there somewhere, he said, “Where is everybody?”  This is known as the ‘Fermi Paradox’.

The process of ‘looking for life’ out there, includes first looking at how life on Earth began, which we’re really not sure about; we do know approximately when life started here on Earth (about 4 billion years ago), but we don’t know how it started!  Which complicates things when looking for life elsewhere. It’s been said that “If we played Earth’s history again, the emergence of intelligent life as we know it, is actually somewhat unlikely.”

Apollo 12 astronauts

However, there is a story that claims that when Apollo 11 reached the surface of the moon, Armstrong expressed astonishment at finding two unknown spacecraft already present on the moon. Armstrong further described these UFOs as being huge and lined up on the far side of the crater’s edge observing the Earth.  The theory originated from NASA’s claim about losing transmission from Apollo 11 for roughly two minutes. Did Armstrong really see aliens during that time?  Apollo 10 astronauts, Stafford, Young, and Cernan heard a certain whistling sort of music while circling the moon. The music lasted for almost an hour and creeped the living daylights out of the astronauts.  The Apollo 12 astronaut, Allen Bean saw a mysterious shining object on the moon.  American astronaut Leroy Chiao was the commander of the International Space Station in 2005, after seeing a series of lights outside the ISS, claims he is 100 percent convinced he was visited by aliens.

These are well-respected, educated men who did not just take up space in school.  So, if we assume that we are being watched, let’s look at some of the theories of how ‘they’ may be watching us:

  1. The ‘Dark Forrest Theory’ says that the reason we can’t see these alien civilizations is because they’re all in hiding. Unlike humanity—whose radio transmissions have long echoed throughout our local galactic neighborhood—these societies have all concluded that it’s simply too dangerous to broadcast their location to potentially hostile neighbors.
  2. The ‘Snow Glob Theory’ says that yes, there are aliens, but they are so much more advanced than us, that they have no interest in watching us for very long. It’s like looking at a snow globe and every once in a while, you’ll turn it upside down to see something a little different, and then leave it alone.
  3.  3. The ‘Zoo Theory’ says that aliens can and are watching us with some interest, but are so much more advanced than we are, that they are really not bothering to interfere with our simple, mundane existence. It’s sort of like us watching an ant colony.
  4. The ‘Been There, Done That Theory’ This is believed by people who can’t otherwise explain things like the Great Pyramids, saying that aliens were here for a while, built some stuff, got bored, and went home.

Fermi, “Where is everybody?”

The fact is that the universe is so vast and the building blocks of life are so abundant in the cosmos, and the number of planets in the cosmos is so large that it’s very unlikely that life on Earth is the only form of life that exists out there,

Whether you believe any of this stuff or not, it is with us to stay.  Earlier this year, a former Air Force intelligence officer testified that he had been told that the United States is in possession not only of crashed spacecraft of “non-human” origin but also alien “biologics.

I’ll probably continue to take up space in the future and keep you posted on any further discoveries of life in space or here on Earth.

 

 

 

Time, Space and the Dinosaurs

by Bob Sparrow

Sputnik

I have been fascinated with space from an early age, and as I have mentioned in previous blogs, my teachers always referred to me as the kid who just took up space in school, but that’s another story.  Most who read our blog are part of the generations who have eye-witnessed the exploration of space first hand.

We remember the Russians, back then it was the U.S.S.R., as the first to explore outer space, as opposed to today’s Russian heart-breaking exploration of Ukrainian space. They opened the ‘space age’ in 1957 with the first satellite to circle the earth, Sputnik, which translated from Russians, means ‘satellite’ – hey, it’s not rocket science . . . well, actually I guess it is!  (Note how small Sputnik is in the attached photo).  A few weeks later, they were the first to send a living creature into space, a dog named Laika, but typical of the Russians, they neglected to send ‘poop bags’ with him, so he returned quite messy.  Subsequently, Americans feared they were falling behind in the ‘race for space’, which we were, so after two mulligans, we finally launched a satellite, called the Explorer, into orbit in January 1958.

In 1961 the Russians etched another notch in their ‘space belt’ by being the first to put a human in orbit around the earth, Yuri Gagarin, which in Russian translates to ‘Neener Neener’.   The Russians had a few other ‘firsts’, one of them being sending the first woman into space, although some say she has still not returned.

“One giant leap for mankind”

President, John F. Kennedy in May 1961, in an effort to put an end to Russia’s dominance in space, made a speech that challenged our scientists to land a man on the moon (and get him back safely) before the decade was over.  While most of our generation remembers where they were when they heard that Kennedy had been assassinated, we also remember where we were in 1969 when we watched Neil Armstrong deliver on Kenney’s promise, and walk on the moon, as well as proving, once and for all, that the moon was not made of green cheese (it was a rumor at the time, kids!).

Clearly the moon landings have been the biggest event so far in human space travel, but since then the launching of various satellites and telescopes that enhance communication and observation, as well as explore other galaxies have taken over the headlines.  In 2017 I wrote here about the satellite Cassini, that took nearly seven years to traveled over 4.9 billion miles to Saturn, made nearly 300 orbits of the ringed planet, took over 450,000 photos (Not all of them got Saturn smiling) and then crashed into the planet that it knew so well, and remains there today.

The next big thing in space happened in 2003 with the launching of the Hubble Telescope, which has provided astronomers with countless new observations about the vast regions beyond our solar system.

And now, we have the James Webb Space Telescope, which was just launched in December of last year (2021), and has now reached its final destination about a million miles from earth, where it will now orbit around the sun.  To say the least, astronomers are giddy!  Why?  Because with this giant telescope we can see further back in time than ever before.  OK, if that statement just made you shake your head, here’s a quick study on the space-time continuum that even those who didn’t take up space in school should be able to grasp. Light is not instantaneous, even though it seems that way when you turn on a light switch, but it is really fast; it travels at a speed of 186,000 miles per second.  OK, you still with me? The moon is our nearest celestial body in the universe, a short 238,900 miles away, it takes light about 1.3 seconds to travel from the moon to the earth, so we are seeing what the moon looked like 1.3 seconds ago.  Expanding that same logic, the Virgo Cluster of galaxies is the largest

I think that’s me in there somewhere!

nearby collection of galaxies at about 60 million light-years from the Milky Way. Still with me? The light we see today from galaxies in the Virgo Cluster started on its path toward the earth at the same time as the age of the dinosaurs was ending on Earth. So, if you were in a Virgo Cluster galaxy today, and you had a telescope powerful enough to study the Earth, you would be able to see the dinosaurs roaming the earth.  What?!!!  Yeah, I don’t fully understand it either!  But I’m thinking that perhaps one day they will be able to figure out how some of us old dinosaurs that are roaming the earth today will be able to actually travel back in time!  Naah, I’m not sure I want to relive all that all over again!!

It is mind-boggling, but so fascinating for those of us that are still just taking up space.
