What is Dark Matter? - Space Documentary 2016 By fitting a theoretical model of the composition of the Universe to the combined set of cosmological observations, scientists have come up with the composition that we described above, ~68% dark energy, ~27% dark matter, ~5% normal matter. What is dark matter? We are much more certain what dark matter is not than we are what it is. First, it is dark, meaning that it is not in the form of stars and planets that we see. Observations show that there is far too little visible matter in the Universe to make up the 27% required by the observations. Second, it is not in the form of dark clouds of normal matter, matter made up of particles called baryons. We know this because we would be able to detect baryonic clouds by their absorption of radiation passing through them. Third, dark matter is not antimatter, because we do not see the unique gamma rays that are produced when antimatter annihilates with matter. Finally, we can rule out large galaxy-sized black holes on the basis of how many gravitational lenses we see. High concentrations of matter bend light passing near them from objects further away, but we do not see enough lensing events to suggest that such objects to make up the required 25% dark matter contribution.

i believe dark matter is also gravity as well of time = 5th dimensional wall?

The facts are simple like the equation, these guys get great rewards yet know jack shit about the universe, like little babies fumbling around in the dark, another wave of nonsense that always ends in doom, it will end in fire, it will end in ice, its lonely? Go buy a teddy bear :)

I am new to this theory, but could it be that some cohesive force/forces which work/s at massive levels of universe, could have become weak beyond a certain distance, and thus causing universe to expand at an accelerated pace? Or it could be that the Big Bang theory itself is flawed/incomplete, causing all scientists to come up with flawed/incomplete equations. The best idea would be to construct the nature of dark energy and dark matter with their observable characteristics, rather than to try to describe them with the help of our understanding/equations of visible matter and energy. And in a situation of weakening attractive forces over distance, the objects should naturally speed up.

dark matter is proof we are living in a simulation.
Virtual worlds created by us are often put together by rules to make things work, especially when our understanding of physics can't be implemented.
Dark matter is one of these rules that were placed by the programmers of our simulation to make things work. -
The big bang- the Universe came from an enormously dense speck of something that exploded. Alas, too many unanswered questions, like where the speck came from. Then, 2 parallel universes collide, making our universe. Once again, where did the 2 parallel universes come from? Does dark matter matter? Its a THEORY, each new one more preposterous than the previous. Do I believe in atomic theory, sub atomic s, gravity waves, magnetic waves, "something occupying the gap between particles and between electron shells and magnetic flux lines? Yes. But the most powerful and prevailing force in the Universe is either Over-inflated egos or stupidity- possibly a combination of both.

The more I see of these science documentaries, the more they sound like the religious crap we've been told as kids. Most of it is guessing and wishful thinking.

we cant feel or see Matter so it must be something we cant control but by trying to connect to it may open up Pandora box which is a bad mistake ..God did not intend us to play with these things learn from it yes but to connect to it is a HUGGGGGGEEE Mistake

We can easily identify trees by their leaves but 90% of the tree is behind the leaves. #DarkMatter.

"Near sub-zero" temperatures??? Really? The temperature is in millikelvin, and kelvin CANNOT be sub-zero!!! @18:10: https://youtu.be/80-1N0sA2oc?t=1090

I'm lost. I keep seeing videos of scientists asking why there's more matter than anti-matter, and here says antimatter is 90% of the universe. so is there more matter or anti matter.
ps:it matters to me XD -
man i do enjoy life but from time to time i watch these videos because space is so interesting to me and i think to myself that how pointless it all is!! how insignificantly small we are!!
there could be another big bang after our universe is gone and there would be a whole other map of the universe after that maybe billions of other species will live in that universe and humans would never exist and when that universe is gone there would be another big bang and something else will exist!!
its like something cooking in a pot that there are bangs over and over again and again and different things exist after each bang and maybe on that level the bangs happen very fast one after another but since we are so small to us that little amount of time is billions or trillions of years so we live out our lives/generations in that small amount of time. it makes me realize how petty our fights are i mean come on at one point this planet wouldn't exist thinking just that makes me sad but as it is "time never stops" everything must come to an end!! -
Ok. I now know about dark matter and dark energy.
Can someone tell me about dark elves now? -
Dark matter or energy could be the super consciousness, omniscient, omnipotent energy present within all matter and space. To analyse dark matter will not be possible because it is a higher form of immanent energy different from the nuclear energy found within matter. Energy from matter can be measured by the formula E=MC squared but dark matter cannot be analysed or measured like matter. This is probably the very nature of the supreme, superconscious soul, God. In Hindu philosophy, the universe can be broken down into 3 eternal elements viz God, souls and matter. God and souls cannot be measured because they are 2 forms of conscious intelligent energy but matter can be measured because their energy is produced from atoms .Dark matter can only be realized by experiencing the merging of the conscious soul with the superconscious soul. Dark energy proves that the universe is one big interconnected cell and God is one and is everywhere.

you can insult logical thinking people as much as you like with your dark matter and string theory,
at the end of the day if think screwing money out of the government for all this bullshit.
but we are destroying this beautiful planet of ours,
its time you started to put more effort into turning the deserts green instead of theorys on bullshit. -
dark matter.
ive seen it in a field in daylight, i believe it was left by a bull.
but ive also seen horses that have deposited it . -
seriously Discovery Channel.. sort out the quality of your videos.. at least 720p would be nice, no need for 4k60... just something clear enough to actually read whats on the screen.

black matter creates it's own energy buy accumulating light in its gravitational pull

there is a proverb that says... if you never seen it with your eyes, don;t testify it with your mouth Photo shop makes nonsense to make sense... no one has ever entered into a black hole let alone the fact that no one has ever seen one... said the scientists.... but we have people who can tell you everyhting about black holes than they could tell what is conciouse... maybe before you study stars study yourself... what is the difference between truth and fact... theory and proof .... if you want to make a vedio make your own research and not astronomers research... there is a proverb that says... if you never seen it with your eyes, don;t testify it with your mouth

People putting their own stupid ideas in the comments, just stop, if you understood science well enough you wouldn't seek approval of those watching a video made for people with the most basic of knowledge, if you think your ideas are right, work out the science behind it, if not, shut up
