UFOs

[Highway Man]

At one time not so long ago, it was science fiction to even think of putting a man on the moon, let alone sending rovers to mars and controling them from the earth. We already have a probe that has reached interstellar orbit and still sending signals back to earth so I don't rule anything out when it comes to outer space and space travel in general. Nothing is impossible.

I absolutely believe that there is life beyond Earth.
I wouldn't be surprised if it was as close as Venus or Mars (although that would be problematic. From the point of view that it could and would be argued that such life might have originated on Earth, then spread there).

I'm with Brian Cox et al on this point : it is not unlikely that Earth hosts the only intelligent life in the Milky Way.

I'm with Brian Cox et al on this point too: the distances between galaxies are so unfathomably vast, it is unlikely that any life form will ever leave its own galaxy.

So, there's likely nothing in this galaxy to come and visit us, and anything from another galaxy likely could never leave there.
Ergo: no "little green men".


And I won't be watching random YouTube videos about UFOs for anything other than schitts and giggles. I'll wait for the peer-reviewed paper, if it ever comes.

our own galaxy is so mind bogglingly big I would think there is other "Intelligent life" but the chances of ever knowing this is highly unlikely, radio waves travel at the speed of light and yet our reach will have been miniscule (this shows 200 years although i don't think we have been broadcasting that long)
the thing is, by the time we discover other intelligent life, it would probably be extinct, and humans will be long gone by the time our fingerprints of existence reaches the other side of the galaxy
It is really difficult to comprehend how big space is

Interesting video if anyone is interested.

This is the rub. Using the Moon landings analogy, comparing it with how we viewed space travel way back when, is a futile as it is pointless.

Humans can now travel ten thousand times further than they could 200 years ago. They might be able to multiply that by a factor of 10 or a hundred or a thousand or a million by the time another 500 years have passed. It still won’t scratch the surface as far as space travel is concerned.
We’d need all the energy we have on the planet, plus the rest of the solar system and a smidgen of the sun, as well as everlasting life, just to be able to ‘pop next door’ in terms of space travel.

No we don't.

Voyager 1 (or 2, I can't recall which) hasn't yet reached the oort cloud and, even when it does, it'll still take another 30 thousand years to cross it.

And it'll be incommunicado in the next decade or so anyway.

Both have reached intersellar space

Both have reached intersellar space

And when will either reach the nearest star?

My point remains the same.

 

[Brigadier]

My point remains the same.

A pointless point.

70 thousand years, iirc.
And even then, it will have been a dead lump of metal and silicon for tens of millenia.

Why is it a pointless point?

Why is it a pointless point?

Discussing lifeless objects aimlessly passing through space, is utterly pointless.

Humans will only ever move around our planet. In terms of space travel, it would be like switching to the next seat on the sofa. Extremely unlikely a human will ever leave our solar system, no matter how hard you want it to happen.

 

[noseall]

And when will either reach the nearest star?

If?

Long, long after they have been forgotten about.

 

[Brigadier]

70 thousand years to fire what is basically a bin of WEEE past our nearest star is not the flex you seem to think it is.

After nearly five decades of travel, Voyager 1 has covered less than 0.06% of the way to the nearest star.

Keep dreaming.

Its got further than you have ever been. I don't recognise you as an astrophysicist so I will pass on your theory
