We first derive the energy-momentum tensor of the massive … WebAnswer (1 of 14): First, gravitons make up gravity waves through well-established semi-classical field theory. We've observed gravity waves for quite awhile (it won the Nobel Prize in Physics in 1993). While we don't know much about dark matter, we do know that it is massive. We know quite a b... irish rover diners drive ins and dives

Webaway electromagnetically. In other words, the dark matter is very nearly dissipationless. 2.2. Collisionless In addition to not interacting with “light” matter (to ensure that energy is not dissipated), the dark matter must be nearly collisionless as well. Even if the dark matter can not radiate energy, collisions will serve to make halos WebNov 4, 2024 · Dark matter could consist of particles called gravitons that appeared right after the Big Bang - possibly from other dimensions, according to a new study published … WebI was watching a documentary that said that the reason gravity is so much weaker than the other forces was because gravitons leak from our universe … irish rover complete dog food
