Black Holes and Interstellar Travel

[AshiharaFan]

I am personally of the belief that we human beings on this planet we call earth are not the only intelligent life forms in this huge, vast universe. Billions upon billions of galaxies. Each galaxy has billions upon billions of stars that are the centers of solar systems. I personally think it is quite arrogant for some people to think that we are all alone in this universe.

The questions are usually asked: "If there are other, intelligent life forms in this universe, why are we unable to make contact?" Why is it near impossible to find a way to travel between stellar systems and galaxies. Is it even possible to make a wormhole?, etc."

While watching a documentary earlier on black holes it occurred to me that perhaps black holes are the reason why we on earth have never been in contact with intelligent, alien life (that's *IF we've never been in contact with other life forms). The gravitational pull of a black hole is so strong that not even light can escape from it. Now that I think about it that's a scary ass thought.

But anyway, two things about a black hole that would most likely stand in the way of interstellar travel are:

1). Gravitational pull which nothing can escape from or resist.

2). They cannot be seen.

And since there are many, many black holes in the universe there is always a chance that something out there attempted interstellar travel (maybe even via a wormhole) and got sucked in by one of those things. Or maybe there are other life forms out there who are also aware of the existence of black holes and are wary of interstellar travel because of them.

What do you guys think?

By the way, I'm far from a knowledgeable astronomy, physics or science guy so I'm sure there is much in my thoughts that are based are ignorance. But I am slightly fascinated with this kind of topic though (intelligent, evolved life on other planets and interstellar travel in the universe).

The center of our galaxy is a black hole so we're being sucked into one as we speak.

Is that why once you go black you never go back?

Yo, that sucks major balls! But from what I understand we (in our part of the galaxy) are a few thousand light years away from it so we in 2015 have nothing to be concerned about. Now those who inhabit our part of the galaxy 12,000 light years from now are screwed.

Hhmmm....you know what? You may be on to something.

I think the big hang up is that it is impossible for anything with mass to achieve the speed of light. Even at the speed of light the distance of the next habitable planet would severely limit the ability of another living being to travel here (given our finite description of life).
Then there are the factors of the environment in the habitable planets and what is the maximum of the evolutionary chain the said environment can support.

Ok?

Oh, well that settles it, then.

Here is a list of potentially habitable planets with distance from Earth and habitability ratings.

Why isn't there a porno named Super Massive Black Holes? Actually, there may be one.

Don't you mean super massive poles?

What if? Everything we see beyond our own Solar System is a hologram....a huge movie screen of sorts....The intelligent life that created all of this knows that we will at best only get so far...the only thing I just thought of is The Voyager....they must have captured it and have it sending back info as if it was outside our SS...

There are seven billion people on planet Earth. No 2 people have the same fingerprints or DNA. In the same way, there are no 2 stars the same, no 2 star systems the same, no 2 planets the same. We don't know exactly what conditions are needed for life to exist. We have the right star and 3 planets that should be the right size in the right zone but only one has life. Is it the distance from the Sun, the magnetic field, the tilt of the axis, the low eccentricity of the orbit, the size of our moon, the amount of water or a combination of all of those. We know that life on Earth was almost wiped out several different times. Life can survive in some pretty extreme environments on earth but it isn't going to be the type that will develop interstellar travel.

Even if there are billions of planets where intelligent life developed without being destroyed in a planetary disaster, the physics involved suggests that travel at near light speed is not possible let alone travel at faster than light speeds. It would take several generations to travel to another solar system. Any interstellar travel is likely to be a one way trip by a civilization who had to leave their planet due to some catastrophe.

No, I mean holes. Like the holes women have on them. I think you just accidentally admitted to watching gay porn.

The holes themselves should not be super massive but taut and tight.

Other than distance, I think time is the other huge separation factor. There could be countless other civilizations out there but whose to say they are going to exist at the same time as us.
