Looking at this there must be plenty of Earth like planets.
That means a very high chance that alien life exist right? So why aren't they here? We'd be there for sure.

We'd be there? Sounds awful confident for a member of a species that has never travelled beyond its own moon.

But we have gone to the moon. Proving it's relatively easy to leave your world.

I like to believe that any type 2 or above civilization refuses to interact with the ones below them.

>> No.5927322

Do we not 'interact' with cattle?

>> No.5927328

Maybe because they're so far away and have the same technological problems we do.

Maybe they are more advanced than us and don't give a shit... Or realised that FTL (or other means of rapid inter-galactic transit) is totally impossible.

Nope, there is actually video of big foot. That's more evidence than for aliens visiting. UFOs don't count. Next you'll be telling me crop circles and anal probs.

lots of people say they think aliens know we are here, but they just dont want to talk to us. i have a theory, what if they dont try to talk to us, because they dont consider us intelligent life?

>> No.5927414

>>5927409
They don't consider you intelligent life, no.

It's a simple matter of what would we have to offer them. Life exists because it can take resources from the universe and survive. If they gave us all their technology how would they benefit? It's common sense, people. Aliens would not be gods any more than we are.

>> No.5927425

>>5927414

>They don't consider you intelligent life, no.

yes, because the idea that aliens operate on such a simplistic human agenda similar to our own makes MUCH more sence, doesn't it?

faggot.

>> No.5927497

Technological trap: a scientific discovery that hints towards great profit but the prototype actually causes an unforeseeable catastrophic failure and the whole solar system gets blown the fuck out. Current canditate is the Alcubierre drive. Nature like her child named Causality more than those wanna-be spacefaring civilizations.

>> No.5927516

>>5927497
The Alcubierre drive requires negative mass, which almost certainly doesn't exist, and all the papers about lowering the energy requirements only work for non-mainstream, untested theories of spacetime. It also can't stop, can't be seen out of, and floods with Hawking Radiation so gets hotter than the hottest known thing in the universe within a fraction of a second. Oh, and if it could stop, it would release a planet-destroying wave of gamma rays that would sterilise space for light-years.

Alcubierre drive is actually congruent with GR - it doesn't violate any known law of physics.

>> No.5927537

>>5927532
The basic idea of a warp bubble is, but as I said, the schemes for making it require less than the mass-energy of the universe require alternate views of GR than what have been tested (and not found wanting).

aliens already visited us. they recorded our minds and now we live in their computer.

>> No.5927559

>>5927532

there's a solution to it, but to make it practically, you need negative mass, which isn't possible

I could count quite a few, but that's not the point. Exotic matter and alcubierre drive can be derived from einstein's equations, which were confirmed true the last time I checked.

The second and first law of thermo, though the latter might be argued around, the former would be violated.

>> No.5927609

>>5927602

you can't derive the drive from the equations. this seems to be a common misconception on /sci.

the alcubier drive creates a distortion in space which is a solution to GR but the drive itself requires things that we haven't detected and have no reason to believe exist. i.e negative mass

>That means a very high chance that alien life exist right?

No, this is a non sequitur.
