Is there such a thing as a dark matter nebula because i heard about it on Star Trek?

Question

If so what the heck is dark matter and is it dangerous?

Answer 1

'Dark matter' is a theoretical material that would account for the differences in observed behavior and theoretical behavior of cosmological evolution. Nobody actually knows a great deal about it (or if it even exists) and nothing about whether or not it might be dangerous in some sense.

Answer 2

You're confusing two quite different things. Dark matter is a theoretical construct to explain certain things about the universe. Dark nebulae are actual clouds of dust which obscure the stars beyond them. There are hundreds of dark nebulae in the sky, the most famous of which is the Horsehead Nebula in Orion. This is number 33 in Barnard's catalog of over a hundred dark nebulae he discovered on photographic plates about a century ago.

Answer 3

Don't believe anything you see on star trek. Some of it is based on real ideas, but none of it is real. A nebula, by definition, is self-luminating so there can be no dark matter nebula. Dark matter is simply matter than can't be detected but appears to be there because of the gravitational effect it has on other matter. Dark matter isn't dangerous, in fact if it turns out that dark matter really exists, then we have it to thank for holding our galaxy together.

Answer 4

It's a theory. Star Trek throws out theories just for the heck of it. It comes from PH D consultants. I watched 3 of them try and justify time travel.

In reading Einstein's concepts on Relativity and stabilization of environment (a human body in motion becomes acclimated to that motion after a period of time, which is why you can stand and walk in a bus or train or plane that is moving) it struck me that it is potentially possible that a human body will acclimated to vast speeds such as near light and may not lose time. If anyone has any writings from Einstein, who must certainly have thought of this one, I'd like to read his explanation for the biological clock slowing down at vast speeds. Humans are not machines nor are that atomic clocks made of inorganic matter. Humans aclimate.

It stikes me there is a CONSERVATION of RELATIVITY as applicable to biological entities. Which can explain why we can't travel at light speeds.

But that's just my own conjecutre, in view of Einstein showing how I could be mislead by his posulates.

Dark Matter, Worm Holes, Folded Space, Black Holes. A lot of educated conjuecture. Just like life planets 30 light years away based on wave undulations.

Answer 5

I dont think there is any thing called "dark nebula" However there is concept of dark matter and dark energy. For the universe to be as it is currently, the calculated amount of energy and mass is not enough. So the missing mass and energy are unknown and are called as dark energy and dark matter. The estimated % of the actual mass and energy is just 4%. 21% is in the form of dark matter and and the remaining 75% is dark energy
