WebDec 21, 2012 · If the universe is flat and composed mostly of matter, then the age of the universe is. 2/(3 H o) where H o is the value of the Hubble constant. If the universe has a very low density of matter, then its extrapolated age is larger: 1/H o. If the universe contains a form of matter similar to the cosmological constant, then the inferred age can ... WebMay 4, 2024 · Scientists know that dark matter does not emit light from any part of the electro-magnetic spectrum, but dark matter has been observed to be influenced by gravity. Astrophysicists are still unsure what dark matter is, exactly. However, they know what dark matter is not, by observing the way it behaves compared to other materials.
