what do scientists know about dark matter? Scientists have not yet observed dark matter directly. It doesn’t interact with baryonic matter and it’s completely invisible to light and other forms of electromagnetic radiation, making dark matter impossible to detect with current instruments.
How do scientists explain dark matter? Scientists study dark matter by looking at the effects it has on visible objects. Scientists believe that dark matter may account for the unexplained motions of stars within galaxies.
What do scientists think dark matter is made of? Most scientists think that dark matter is composed of non-baryonic matter. The lead candidate, WIMPS (weakly interacting massive particles), are believed to have ten to a hundred times the mass of a proton, but their weak interactions with “normal” matter make them difficult to detect.
Why are neutrinos not a good candidate for cold dark matter? If all dark matter were neutrinos it would take an enormous time to form gravitationally bound structures because it’s exceedingly hard for neutrinos to lose their energy and slow down enough. And this is why the dark matter can’t be neutrinos.

why dark matter get cancelled?

is zero point energy dark matter?
The steady and dynamic states are studied for a spherical cloud of zero point energy photons. The ‘antigravitational’ force due to its pressure gradient then represents dark energy, and its gravitational force due to the energy density represents dark matter.
what percentage of a galaxy mass is dark matter?
And it’s tiny on the scale of the most abundant, mysterious matter in the galaxy: the dark stuff. Again: 84 percent of the galaxy is made up of dark matter. Dark matter doesn’t seem to interact with normal matter at all, and it’s invisible. But our galaxy, and universe, would fall apart without it.

What is dark matter in simple words?
dark matter, a component of the universe whose presence is discerned from its gravitational attraction rather than its luminosity. Dark matter makes up 30.1 percent of the matter-energy composition of the universe; the rest is dark energy (69.4 percent) and “ordinary” visible matter (0.5 percent).
Why do we believe there is dark matter?
Dark matter has been given this name because it doesn’t seem to interact with regular matter in any way. It doesn’t collide with it, or absorb energy from it. We can’t see it or detect it with any of our instruments. We only know it’s there because we can see the effect of its gravity.

Is boron halides a Lewis acid?
As has already been mentioned, boron halides are electron-deficient molecules. As a result, they tend to act as strong Lewis acids by accepting electron pairs from many types of Lewis bases to form stable acid–base adducts.
What is the mystery of dark matter?
The rest remains somewhat of a mystery. A dark one. Astronomers and cosmologists think around 25 per cent of our universe is made of something called dark matter, and the remainder—around 70 per cent—is what’s known as dark energy. Dark matter doesn’t interact with light, so we can’t see it.
