Theories on dark matter
Webb10 juli 2024 · Dark matter was proposed to explain why stars at a galaxy’s far edge were able to move much faster than predicted with Newton. An alternative theory of gravity might be a better explanation. Using Newton’s laws of physics, we can model the motions of planets in the Solar System quite accurately. Webb11 apr. 2024 · Dark matters are substances that do not absorb, reflect or emit light and hence not visible. Dark matter is a non-interacting substance, and this is what makes it dark and mysterious. It is considered that about 5 percent of the universe is known to us. The rest 95 percent includes about 27 percent of dark matter and 68 percent of dark …

Clark. For decades, astrophysicists have thought some sort of invisible dark matter must pervade the galaxies and hold them together, although its nature … Webb17 aug. 2024 · The theory of dark matter was proposed in the 1970s to explain the rotation curves of galaxies, which appeared inconsistent with the observed distribution of luminous matter (i.e. baryonic matter ).
Webb9 apr. 2024 · Dark matter, the elusive substance that accounts for the majority of the mass in the Universe, may be made up of massive particles called gravitons that first popped into existence in the first moment after the Big Bang. And these hypothetical particles might be cosmic refugees from extra dimensions, a new theory suggests.
