Yes, black matter does have weight. While it is not visible or detectable through traditional means, it is believed to make up a significant portion of the total mass in the universe.
The weight of black matter is determined through gravitational lensing, which is the bending of light by the gravitational pull of massive objects. Scientists also use the observed effects of black matter on the motion of galaxies and other celestial bodies to estimate its weight.
No, the weight of black matter is different from regular matter. It is estimated that black matter makes up about 27% of the total mass in the universe, while regular matter only makes up about 5%. Additionally, black matter does not interact with regular matter through electromagnetic forces, making it difficult to measure its weight.
Yes, the weight of black matter does play a role in the expansion of the universe. It is believed that the gravitational pull of black matter helps to slow down the expansion of the universe, while dark energy (another mysterious force) counteracts this and causes the universe to expand at an accelerating rate.
No, the weight of black matter cannot be measured on Earth. This is because black matter does not interact with regular matter and therefore cannot be detected or measured through traditional means. Scientists can only estimate its weight through observations and calculations based on its effects on the universe.
