Interesting question

[Blazed Deafy]

i didnt know that the black hole is invisible to human's eye. i was expecting black hole to be massive yet you say its tiny? are you referring to one type of blackholes? did you know that theres opposite of blackholes? talkin about balance...schiesse

Listen and learn.

A black hole is a mass which will eventually approach infinity. As it gains mass, it procures mass; that is to say that a larger a black hole becomes, the larger it will become. Very redundant. However, redundancy is the main principle of black holes. They contain so much mass in such a small area that even light itself cannot escape the gravitational pull of the black hole.

That is why we cannot see them.

Alright listen and learn! There is a supermassive black hole at the center of our galaxy and scientists suspect that there is actually one at the center of every galaxy especially of the spiral type.

You can kind of imagine this as the spine that holds our galaxy together with its massive gravity. Now black holes actually are absolutely gigantic in terms of mass however relatively small in terms of size due to that mass. Its mass is so great that its gravity actually does not allow light to leave its surface. This point is called the "event horizon". This would be the reason that you can't "see" a black hole because no light is escaping however you can can get a general idea of its properties from the way other masses act around it. However black holes do actually lose mass through a type of radiation I believe called Hawking radiation predicted by physicist Stephen Hawking. This is about the extent of my knowledge of black holes but now I move on to life.

Firstly, I think that for life to exist there must be water. Water has so many important characteristics I don't see how its possible without it, in fact I'm fairly certain there are no forms of life on earth that survive without it. So if we are to find planets with life on them that must be a first check we do. In terms of probability. We've only been able to find extra-solar planets for the past few years and already have founds hundreds. Not to mention the fact that they are all within around 10,000 light years from us (still well within our own galaxy.)

The certainty of life beyond our own will come when we have actually found how life came to be here on earth. There is an experiment, I forget the name, where they put the initial elements from earth in a beaker then shocked it with electricity and actually got some amino acids which are the basic building blocks of life. This is easily attainable in other areas of the universe but it must be proven that life can actually come from this. I think that once that is done there will be no refuting that there truly is almost certainly life outside of earth.

Thanks for reading! I realize this was really fucking long but hey, what can I say, I love science lol :thumbsup:

Black holes are invisible because they absorb light instead of reflecting it. Therefore rendering them invisible to us. And yes most black holes are only an inch or two in diameter.

Hawking radiation is the radiation that is put off by Black Holes. It's called Hawking radiation because Stephen Hawking was the one to discover that Black Holes put off their own heat.

And In general relativity , an event horizon is a boundary in spacetime, an area surrounding a black hole, inside which events cannot affect an outside observer. Light emitted from inside the horizon can never reach the observer, and anything that passes through the horizon from the observer's side disappears.

Consider this. The probability of life existing somewhere else in the cosmos is next to zero. However, the sample space that we are taking the information from is infinite. This means that although the probability is impossibly small, it still exists because of the infinite nature of the space itself.

Ok, that makes sense. The only negative aspect to this idea though is that it can be stretched to prove the existance of anything and everything.

I see it like this, if the universe is really infinite, like is commonly accepted then everything that you can imagine is true because you are bound to eventually come across that extremely rare case with infinite trials. Lets say the odds of a pig born with wings is 1/100000000000000000000000. If you have infinite trials you will eventually find that pig born with wings. This is the same for any other probability. What is the probability you will win the lottery on Wednesday if you have infinity lottery tickets? I would say you have a 100% chance of winning.

If you are willing to accept that aliens exist because there are infinite possibilities for them to exist, you are basically saying nothing more than "anything is possible". In a sense that is what everyone who replied to this thread is saying in one way or another, including me, but I guess I choose to camp with the alien skeptics instead of alien enthusiasts.

My point is basically that our minds cannot fathom exactly what infinity is, and our mathematics will reflect that. I admit that there is a chance for life to exist out there, but I still think it is astronomically low.

You and I may not be able to fathom infinity, but there is a probability that someone will be born who can
