Alien visiting earth. Curious what others think.?

Question

Ok, I'm not an "aliens maaaan" nut job. But sometimes my family and friends act like I am. I just think it is very close minded to rule out the possibility of other life in the cosmos. The universe is so big that we can't even fathom it's size. I mean, it's theorized that there is no end. It doesn't just stop at a limit.
So to definitively say nothing else is out there is crazy.
But I am asking about intelligent life being advanced to the point they can travel faster than light and make it here.
Faster than light travel some think is impossible, but 75 years ago scientist theorized that faster than sound travel would cause a pilot to incinerate and disappear.
I believe that intelligent life is rare enough in the universe that if something else did discover us, why wouldn't they be curious about us? If we ever make it to a different solar system and find a race of life form we would study it.

Answer 1

("Alien visiting earth. Curious what others think.?")

---------------------------------



Yes, there is some circumstantial evidence that extraterrestrials have already visited Earth in the very recent past, and there may have been some sort of technology exchange. I kid you not, that is the truth.

We humans are not even close to having a theory of all four forces of nature, yet we just proclaim to the rest of the Universe -- what is possible and what isn't. There is tons of unknowns about this Universe that we do not yet have answers for. As such, we should not be projecting our own limitations on other extraterrestrial civilizations. We humans simply do not know what new physics may one day spring up and change everything. When we can put energy into the Planck scale (scalar fields) and change the fabric of space-time (in a controlled fashion) into any local configuration we wish, then we can begin to speak with some authority about what is or isn't possible in this Universe.

"75 years ago scientist theorized that faster than sound travel would cause a pilot to incinerate and disappear"



No, they didn't! The press wanted to make the attempt to break the sound barrier more dramatic so they invented all sorts of lurid stories. The common argument is that "they" said it couldn't be done but then "they" did it. The problem is that the first "they" isn't the same as the second one - it's a completely fallacious argument. It even has it's own name, but I can't remember what it is.

Answer 3

Yes, I think there are intelligent creatures out there, and that if they found out about us, they would be just as curious about us as we would be towards them. After all, curiosity and friendliness is needed for a species to survive.



But personally, I don't think they have been here or are here. If they had, they would tell us. Think of it like this: If me wet an alien civilization which did not know of our existence, we would try to establish contact, not quietly study them in secret.



I certainly hope that we will at one point get to at least contact an alien species. Have you heard about the Wow Signal? It's a signal picked up by scientists from outer space, which was similar to artificial radio waves we send out into space. So maybe that signal was from an alien race trying to find something, just like how we send out signals to find others.

Answer 4

I think they are likely out there, but they've never been here.



If they are advanced enough to circumvent the speed limit imposed by the speed of light, then they are very very advanced. This leads to a few possibilities:



The advancement of their society has lead to benevolence, and they choose to stay hidden while studying us to avoid contaminating our advancement. In this case, they could use their technological advantages and we'd never know they were here.



They don't care either way. In which case, if they visited, they'd have no reason to hide, they are far more advanced and we pose no threat.



They are malevolent. In which case if they could come here, they would have already done it and taken Earth for there own before we polluted it any further.



This leads to the conclusion that they just haven't visited us. I hope for their sake that when we discover a way to travel between stars that many of them are not the benevolent sort - we certainly aren't.
