Before there was an Earth, there was just a big cloud of gas and dust floating out in the universe. Before there was a universe ... well, before that is a point that physicists spill a lot of ink over. We don't know what happened before the Big Bang gave birth to the universe, ...
Was the big bangreallythe start of everything? A form of 'nothing' came before the big bang. But what if 'nothing' actually meantsomething? A vacuum chamber has been made by NASA to try and recreate a state of total nothingness. In this space, they have pumped out the air, and froze...
What Came before the Big Bang? 来自 Nature 喜欢 0 阅读量: 37 作者: M Bojowald 摘要: Was the Universe before the Big Bang of classical nature, described well by a smooth space–time? Or was it in a highly fluctuating quantum state? This is one of the most basic questions that we ...
Some variations on the big bang go down a little smoother than the original. In the simplest version, the beginning of time is a sharp point, where everything we currently observe was mashed into a ball of energy smaller than an atom—then burst outward, duh. But what came before? Physic...
Our universe may have started not with a big bang but with a big bounce—an implosion that triggered an explosion, all driven by exotic quantum-gravitational effects
The indisputable evidence is that nothing is ever gained or lost, the sum remains the same. You should learn some basic cosmology before making such a...
"At the heart of the mission is one of the billion pound questions of physics," the ESA's David Parker said in a statement. Common cosmological questions What came before the Big Bang? Because of the enclosed and finite nature of the universe, we cannot see "outside" of our own univers...
novelist (“Einstein’s Dreams”) to introduce us to a “small platoon of physicists” who focus on figuring out such things as what happened at the very first moment of the big bang, whether time or anything else existed before it, and exactly how we distinguish the future from the past...
If that all sounds rather trippy, it is — because scientists don't yet have a way to peer back to even the instant of the Big Bang, much less what came before it. There's room to explore, though, Carroll said. The detection of gravitational waves from powerful galactic collisions in ...
