I find it strange that these scientists assume that they know the universe using their fancy telescopes. Then again, I guess that once we reach their elite status, we'll also get an equally big head that assumes we know how much the universe is missing.

lol@people even pretending they know anything about what governs that which rules our universe as if we even discover 1 millionth of that which exists.

simple fact is all us humans have are guesses and wishes in theories that may or may not be real

get the # over your self centered egos and realize we don't know jack

because we haven't seen jack

till the day we explore 1/10th of what is actually out there

we are doing nothing but ASSUMING we know whats actually going on.

Another answer to "where is all the stuff that exerts the gravity that holds the galaxy together" besides 'Dark Matter/Energy' being the answer could be that our tentative understanding of gravity itself is incorrect. Perhaps a greater understanding of gravity will eliminate the need for this undetected dark matter and dark energy to exist.

I'm not saying dark matter doesn't exist -- I'm just saying that it isn't the only answer to the problem of a galaxy's gravitation.

I'm also not picking on scientists -- they would be the first to tell you that gravity is far from being totally understood. Scientists don't yet even know why matter has mass, let alone why and how that mass exerts a gravitational pull.

Physics still has a long way to go. That's not a knock on the physicists, that's just the way it is. I think science as a whole has done a pretty good job trying to explain the universe so far.

you think that its just some thrown-together 'guess' about what is going on, or do you have a hard time realizing that this study has been going on over the last 30+ years? just because you haven't 'seen' it doesn't mean it's not there. can you see gravity? no, but it is definitely there because it's holding you in your chair.

how about watching the video first then commenting instead of the other way around?

96% of our universe isn't missing!!!

Its not been discovered. So really, what we have discovered is what we know which is 100%, from a certain point of view.
