We know it exists, we just don't know what it is //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

alot like black holes. we can't literally see a black hole.

didnt they actually create some dark matter in one of the hyper collider's (sp?) in Europe?
maybe im wrong... i just thought i remembered hearing something about it

anyways, i really dont know much about this stuff at all but im enjoying teh reading of this thread very much... please contiue

no. but they did have protesters thinking that they would create a black hole that would envelope the earth. some scientists even thought it was possible.

yeah, i do remember that fiasco

dark matter and dark energy. although it's existance is hypothetical.

I always wonder why dark matter doesnt interact with light?

They will/are planning to use devices such as the Large Hadron Collider to try to figure out what dark matter is, etc.

some scientists also believe that tiny black holes pass through the Earth all the time.

look where we were 20 years ago...
where the hell will we be in another 20?

****

we are still in the same place as 20 years ago. we havent really gone anywhere that we havent been in the last 20 years.

it's not a hop skip and jump, to go from the speed of sound, to the speed at which we need to effectively travel in space. it's a huge gap in technology between the 2.

No one can really answer that until we figure out what the stuff is.

Right now the only real way scientists know that dark matter interacts is through gravity. Everything else would, in effect, pass right through it (or it would pass right through the object).

Another question that needs to be asked is;

If we ever do figure out a way to safely travel at the speed of light (or even a significant fraction of the speed of light), is it even moral or ethical to send a human on such a journey considering the effect it would have on the travelers perception of time compared to the Earth? For even a short journey (from traveler's perspective), the Earth (and the people on it) as they knew it would not exist upon their return.

is there an accepted rate at which time slows down per the speed you travel?

i think its the lorentz transformation.

What ever happened with that black hole experiment?

What ever happened with that black hole experiment?

it's a long running experiment in europe. it'll take alot of time to analyze their findings.

What is the meaning of "now", "present"?

You can never see the world as it is, only as it was.......
