Have Aliens Ever Visited Earth, or Likely To In The Future?

Excellent lecture here by physicist Richard Feynman.

"Altered or synthetic content"?

I've been a fan of Feynman, even before I knew more than the bare bones of his scientific career or had read any of his own books. My introduction to him was in Ralph Leighton's book Tuva or bust!

If that's all, that's fine. I expected it'd be something innocuous like that, given the uploader.

This is actually a pretty interesting topic. Since they rebranded as UAPs, there have been many more credible people coming out and claiming we're being visited.

Personally, I don't buy it, not for one second.

I once read a collection of essays all about the possibility of intelligent alien life and came away more pessimistic than before. One made the claim that life existed as single-celled organisms for 3 billion years before it made the leap to multi-celled. There is always a presumption that if you find life, it will eventually evolve into bigger and better organisms.

My favourite saying on the matter is 'there are two possibilities, either we are alone in the universe or we are not, and both are terrifying.'

I've seen a few aliens around Hull over the years.

This is part of, what must be, the most interesting topic for discussion available.

Aside from the whole "alien" subject to muse about, I find it enormously interesting just staring at the night sky wondering.

A question often asked is "How big is the Universe?".

Well, here on Earth, everything is limited, how long people live, how long our fellow creatures live, how long our natural resources will last, etc.

So what if the Universe has no limits or end of life, we simply cannot comprehend anything without limits.

I find it extraordinary that, when I look at the brightest stars in the sky, I'm actually looking at them as they were tens, hundreds or thousands of years ago...or longer. They are so distant that the light from them, even travelling at 186,000 miles per second, has taken years to reach us.

And when it comes to the nearest galaxy to our own Milky Way, the Andromeda galaxy that is visible to the naked eye, when we look at it we are seeing it as it was two and a half million years ago.

I need a lie down now...

I think of it like this: a handful of people are involved in space study compared to the human population as a whole. Humans are the only species that can explore space in that manner. And humans have been exploring off the planet for about 100 years, let's say.

A small proportion of one species for not very long (in the bigger picture).

I just think the numbers are too small for anything to happen the other way around when it comes to visiting Earth.

It is fascinating to try to comprehend the size of the universe. I don't really know where I stand on the subject, mainly due to this incomprehension. 

I don't think there can be an edge of the universe as such because there can't be a state of nothingness beyond. I also wonder what the universe is within because I believe there has to be something beyond it, so are there layers to existence in this sense, parallel universes wrapped around each other? 

I believe in a God but I don't know what form that God takes. I simply believe that whatever created the universe is God, whether that is the kind described in holy texts or even the big bang, I do not know. I do question the big bang theory in that I wonder what caused that explosion; did something have to already exist for that explosion to take place? But then what created that catalyst? 

Going back to aliens, I believe in aliens simply because of the trillions of planets that there are, surely there is at least one more with life on it. I do not believe that they have visited Earth, however.

One of the best takes ever on the universe, only bettered by Douglas Adams

 

[Padge]

Because space is allowed to expand faster than the speed of light we are limited how far back we can see in time by observing the visible universe. That is because the far edges of the universe are travelling away so fast that light cannot catch up for us to see it. We therefor have the perception that the universe is around 35 billion years old as that is as far as we can see, anything beyond the visible edge can never be seen.

That means that the universe can be infinite and not finite. What does this mean, well in an infinite universe there are infinite possibilities which means that their must be another intelligent life form out there somewhere.

Caution, scientists often say that claiming something is infinite is just an excuse for saying we don't know.

Just got up for a waz... what's that strange neon glow coming through the curtains..?

There's someone flying outside the window... the glow just flashed a few times... I'm going to investigate...

If I just carefully pull back the corner of the curtain here... the glow is almost blinding..! I can here a strange whirring noise... 

...OH MY GOD!!

Yeah, just what I thought! It's the creepy, pervy neighbour trying to see into my house again with his drone! 

Get a good look, did ya?! 

#####!

Oh well, he'll have got a bit of a shock to discover that I sleep naked!! Back to bed...
