Yes this is true. We have recently discovered dark matter exists with the help of the Hadron particle collider, but can not see dark matter. (not yet any way)
Some can, some cannot
false: matter cannot be destroyed
Yes, true steam (you cannot see it) is matter in the gas form.
Yes, that's quite true! For more information, read sources such as Wikipedia on "dark matter" and "dark energy". Current estimates are that something around 68% of the mass-energy in the Universe is in the form of dark energy; 27% is in the form of dark matter; and about 5% matter of known types. Nobody really knows much about "dark energy" or "dark matter" - only that they exist.
true
The ideal line is a concept. A line that is drawn cannot be a mathematically true line since it will have a thickness - no matter how small. Also, it cannot be infinitely long - no matter how large.
No.We know very little about dark matter; there are some ideas, but, as yet, nobody knows for sure what it is. What we doknow about dark matter, however, is that it interacts very weakly with other matter. Dark matter and "normal" matter are intermixed throughout space; if there were some catastrophic annihilation interaction between the two, we'd see the electromagnetic signature of that in observations of galaxies and galaxy clusters.
Nobody knows. There are several theories, but physicists don't yet know which is true, or even if any of them are true.
Dark Matter is that which we may call Space. That which takes up about 90% of the universe. It does not exist only in what the term represents i.e There is dark matter or space between the Earth and Mars. It is only dark because it neither absorbs nor reflects light. Take the word Love, it is but a word but it is what it represents that counts. That the universe is expanding is true but it is not Dark Matter or Space which causes the expansion, only the distance between objects.
A broader answer would still be no. There is no consensus on what the so-called "dark matter" is.
I know it,s not true cause all jutsu are fake.
I've never seen my dog look up.
