After dark matter first clumped together, it attracted large clouds of hydrogen. When the clouds grew large enough, the heat and pressure from gravity started fusing the hydrogen, igniting the first star. Simulations predict that these first stars were enormous, perhaps hundreds of times larger than our sun.Some unknown entity intervening in this process in the early universe could have caused these "oscillating" particles to decay as matter more often than they decayed as antimatter. Consider a coin spinning on a table. It can land on its heads or its tails, but it cannot be defined as "heads" or "tails" until it stops spinning and falls to one …
v. t. e. The Big Bang is a physical theory that describes how the universe expanded from an initial state of high density and temperature. [1] The Big Bang theory was inspired by the discovery of the expanding Universe by Edwin Hubble. It was first proposed in 1927 by Roman Catholic priest and physicist Georges Lemaître. This year marks the 90th anniversary of a mind-boggling discovery: that the universe is expanding. The discovery was spearheaded by Edwin Hubble, for whom the orbiting Hubble Space Telescope is ...
