Are we alone out there?

[_CyberGhosT_]

There's got to be life out there somewhere, the universe is so vast, it's pretty much incomprehensible...

I believe there are other forms of life out there, some we may not even recognize as "beings". One certainty for sure, I never ever want to meet any of them. You don't know, to them we could be beasts of burden, or worse yet a food source. I will use my imagination and picture friendly weirdo's visiting, oh wait that's my in-laws
Seriously though, the numbers say we are most likely "not" alone, but for the vastness of space life on earth could be very different and not in a good way. Stay Frosty

With our technology yes, but with their technology maybe a matter of minutes

No chance for organic life to do so unless they had the ability to bend the laws of physics.
The nearest large galaxy to the Milky Way is Andromeda, which is 2.5 million light-years away. Assuming an alien civilisation lived there and wanted to travel to the Milky Way, even if they had a spacecraft that could travel at the speed of light (which is assumed impossible according to Einstein's theory of relativity) it'd still take them over 2½ million years to reach the Milky Way.

I guess if said alien civilisation were similar to the Reapers from Mass Effect they could reach the Milky Way eventually, but by the time they did humanity would've already been extinct for a long time. We're talking tens to hundreds of billions of years.

ok , but i assume there many things we don't know yet about the laws of physics.Actually there is a theory, that through black holes you can make a shortcut.I think in the far future some people may read these conversations in a future museum and laugh about our current knowledge.

There are some ways we could travel "faster" than light but our technology is nowhere close to achieving any of them, One is space warp, yes Star Trek was right, it's possible. The problem with it is the absurdly high amount of energy necessary to achieve the effect.

The other is wormhole technology, (Yay! Farscape was right!) but it not only requires absurd amounts of energy but a way to keep both ends of the hole open for long enough for a ship to pass... That may require dark matter manipulation and right now we can't even detect dark matter, much less manipulate it in any way.

Let me just point out that by absurd amount of energy I don't mean a few reactors or even what the sun produces by second... think about the entire mass of Jupiter converted into energy... you'll be closer.

Now I won't deny there may be other ways we have not figured out yet or that an advanced alien civilization may have solved the energy/dark matter problem but that is pure speculation.

 

[RoboMan]

Of course there is. If we keep and keep discovering new species that are long extinct on our own planet, why wouldn't there be life on other planets or galaxies? Still, if we can't even explain how our galaxy even emerged or who did so, how can we manage to find aliens lol

black holes you can make a shortcut

If you crossed the event horizon of a black hole you'd never be able to cross back. Gravity's infinite inside the singularity of a black hole and it'd take an infinite amount of energy to escape it, which is obviously impossible to generate as it's, well, infinite.

I think what you're referring to is a worm hole, where you go in one side and pop out at a different place in the universe. Sadly, like you said it's just a theory. Even if we could prove they exist, and open one, we'd have to keep it open on both ends (which as @mlnevese said would require an astronomical amount of energy). Even so we'd have no idea where those who went through the worm hole would pop out at.
Sure is a cool concept though. Maybe we can get Elon Musk on it after he's done with the whole colonising Mars thing.

Time traveler from Russia. It is hard to hear, background music is too loud. But then again I have bad hearing.

time travel - Bing video

 

[ForgottenSeer 69673]

This one has a few different people in it. One appears to be a trans person. At first I thought it was a woman but then she said man. But she looked like a woman. time travel - Bing video

And you didn't count parallel universes lol

Also multi dimension universe.

 

[JiSingh12]

I am one of those things you earth people call aliens, however, on our planet we are known as humans, and you earthlings are the aliens.

 

[DeepWeb]

What if OP is an alien and he's trying to test us?

 

[Cortex]

What about the Vulcans, the Romulans, Ferengi, & of course Deanna Troi the half-betazoid half-human lady? The Gorn that Kirk fought - Not forgetting that the Vulcans invented 'Velcro' !

There are no aliens on Earth... we're all human here... nothing to see here, move along...

Agreed, and all we "know" about Physics is how the laws apply to "us" we have no clue how these laws that we barely understand could apply to others constructed differently, we don't know how the laws of physics would apply to another being from out there. Our time here has been a drop on the head of a pin compared to the age of the universe, honestly I am willing to bet we know far less that many will admit, we cant know much seeing all the eons we were not present here, other civilizations could have come and gone while we were some primordial soup critter
Neil Degrasse Tyson says it best, if you are abducted swipe a tool or anything close at hand to prove you're case and separate you from the crazies. lol
Either way, Stay Frosty. MT

No not Black holes, worm holes and we can damn near create those. they serve to kind of fold space in a manner that is a short cut for us. Problem is we cant keep them open long enough, and cant make any of mentionable size. We will know which country does it first, because I have a feeling everything around the site will get transported to a place "elsewhere".
I can hear the collective "Oops" now rofl.

 

[BoraMurdar]

Mathematically , we are not alone in the universe. Technically, we might not be able to prove it, ever.

 

[jackuars]

Actually we are the aliens to some other lifeforms elsewhere in the universe

So yes, we exist

 

[spaceoctopus]

Interesting topic and answers Lets just hope we are not discovered first, by some super advanced Alien race...like the Covenant , in the Halo Universe :X3:

At least we have some people here on MT, with great knowledge about space, matter, physics and principles of biology, to form a resistance in case of an invasion

 

[Arequire]

like the Covenant

I'd take Covenant over Flood any day.

It appears exotic matter could be used to keep a worm hole open. Wormhole - Wikipedia
