Reverse the film of our universe's history, and things seems to get mighty strange in the last reel. What began in physical harmony, propitious for planets, humans and domestic appliances, has reverted to hell: temperatures hotter than the sun's core, an exotic...
Assumptions (or prejudice) will remain necessary for knowing the precise state of the Universe, which cannot be fully justified within science itself.Martin BojowaldNature PhysicsPENROSE, R. 2011. What Came Before the Big Bang? Cycles of Time, London, Vintage Books....
sit perfectly solid forever until a breeze came through. At some point, that "breeze" did come through. It stopped being metastable, inflating into the universe we know. This theory doesn't break the laws of entropy, but it doesn't explain entropy's issues with our current universe, ...
But what came before? Physicists such as Stephen Hawking tried to restore a kind of timelessness by getting rid of that starting point, imagining a universe with no clear “bang.” You can wind back the clock to the edges of those first moments of existence, but asking what came before ...
What came before the beginning? Xuanyu Han/Getty Images It's a mind-boggling question that has intrigued scientists theologians, and the curious alike for centuries: What was before the Big Bang? Roughly 13.7 billion years ago, the entire universe existed as a singularity, a point smaller th...

I don't think we can assume SOMETHING happened pre Planck time, the idea the U came from nothing has to be considered, as if we assume it came from SOMETHING then where did that something come from - the question can be pushed back ad infinitum. Yes we don't have a ...

What came before the big bang?Posted by Sean Brazell in physics, space Jan 42016 Some people take the new year as an opportunity to contemplate their goals; Alan Lightman, writing in the January issue of Harper’s magazine, takes the opportunity to contemplate the creation of the universe....
Scientists now think that a large proportion of these molecules came from outside planet Earth. Comets and asteroids could be the missing links of a long chain.科学家们现在认为，这些分子中有很大一部分来自地球以外的星球。彗星和小行星可能是生命的长链中缺失的环节。The chain began with the simple ...
