This is a very delicate subject to astrophysicists. Why? Because it forces them to believe in something that just can not be proven and probably never will.
Let me explain Dark Matter is nothing but has density, weight and gravity.
I know the brain goes Whoa! Then it is something, right ? No because there is no substance.
Let me illustrate the problem with a metaphor of an elephant for the universe.
Picture an elephant (Loxodonta Africana) that normally weighs about 12 tons. But when you weigh that elephant, that acts and behaves like an elephant, you find he weighs only 1,104 pounds, about half a ton. The elephant should not be able to move or act or have the strength to do what he does unless he weighed 12 tons. But every time you weigh him he is about half a ton. Where is the other 11.5 tons? That is the problem!
In our universe we watch the most amazing things and weigh the observations but what should be there and what is there doesn’t make sense.
Here is the break down: Results from the WMAP team in 2008, which combined data from the CMB and other sources, indicate that the universe today is 72% dark energy, 23% dark matter, 4.6% regular matter and less than 1% neutrinos.
Wow 23 % dark matter and 72% dark energy that’s a lot of nothing!
Now you understand that nothing has to be there or the universe can’t be doing what its’ doing.
Now I understand why computers just will not work no matter what you do to them.
It’s Dark Matter in the computer! 🙂

From my understanding, dark matter and dark energy are not truly nothing. It’s more that we don’t understand:
A) What they actually are. In dark matter, it could be WIMPs (weakly interacting massive particles), MACHOs (massive compact halo objects), baseballs (literally baseball sized objects), or just about anything else that we don’t really understand. In the case of dark energy, there may be some repulsive force, similar to gravity, that acts on even larger scales to repel all of the objects in the universe.
B) Whether the dark and energy are in fact really there or, quite possibly, whether the currently known physical properties of the universe simply are incorrect, necessitating a new theory, as in the case when Newton’s Laws of motion were shown to be perfectly fine within a limited framework, but significantly off on the larger scales of the universe and smaller scales of quantum mechanics.
So, if we assume our current knowledge of relativity and quantum mechanics to be correct, then dark matter and dark energy are very real and very poorly understood. If we assume that they do not exist, then we are sorely in need of some new physics theories.
Either way, it just means that we don’t know everything. One of the great things about science is that it allows us to admit this fundamental truth and to continue to seek for ever greater understanding of our universe.
Dark matter, as the name suggests, is dark. That’s, we cannot see it. Many say dark matter and dark energy is what the universe is mostly made of and search for it elsewhere. But have we ever searched for it in ourselves, in this earth. We know vacuum is nothing, made of nothing.But studies must be conducted as to see what this nothing is made of. There cannot be nothing called nothing. There’s someting in nothing, and we call it dark matter.
So, i believe, vacuum is made of the mysterious dark matter and studies should be carried out towards this……
Wow! I don’t know what to make of this so-called
“dark matter”! Is the universe made up of mostly
hydrogen as I’ve bend led to believe, or is it made up
mostly of this dark matter? It’s invisible, they can’t
prove it 100%,where is the proof? It seems to me that
beliefe in dark matter, is like beleif in God! Maybe
it is God! It LOOKS like God;he’s invisible too.
The strange thing is that dark matter isn’t made off atoms. We can’t smell it or see it, no we interact with it in another way
From what I know human perception allows us to sense 10% of matter, in only about 10% of the possible ways, so we can truly only experience 1% of existence. All our technology is based on what we can perceive. Does it not makes sense that it is something, we just haven’t developed (through evolution or science) the means by which to interact with it? We have a color spectrum based on human frequency range, the same thing with sound, this dark matter could be interacted with if we could tune into that frequency… But which way do we try first? Super high or super low? Or all the way in one direction, even then it could be the wrong means by which to interact… there is much work to be done.
It’s actually a cool and helpful piece of info. I am glad that you shared this useful information with us. Please keep us informed like this. Thanks for sharing.
