because there's no way one could measure what happened at them. Since events before the Big Bang have no observational consequences, one may as well cut them out of the theory, and say that time began at the Big Bang."
There are also some very big questions the big bang theory doesn't address: What happened before the big bang? According to our understanding of science, we can't know. The very laws of science break down as we approach t = 0 seconds. In fact, since the general theory ofrelativitytells...
For Stephen Hawking, this moment was all that mattered: Before the Big Bang, he said, events are unmeasurable, and thus undefined. Hawking called this the no-boundary proposal: Time and space,he said, are finite, but they don’t have any boundaries or starting or ending points, the same...
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 may ask once it is accepted that there was something before the Big Bang. Loop quantum gravi...
Hawking wrote: "Events before the Big Bang are simply not defined, because there's no way one could measure what happened at them. Since events before the Big Bang have no observational consequences, one may as well cut them out of the theory, and say that time began at the Big Bang....
The theory reveals a contracting universe before the Big Bounce, with space-time geometry that otherwise was similar to that of our universe today. Bojowald found he had to create a new mathematical model to use with the theory of Loop Quantum Gravity in order to explore the universe before ...
