Don’t have time to read Stephen Hawking’s A Brief History of Time? Don’t worry. In two and a half minutes, The Guardian’s Made Simple series explains why black holes are doomed to shrink into nothingness then explode with the energy of a million nuclear bombs.
MinutePhysics takes a closer look at the friction between religion and science, going all the way back to the big bang. It turns out that maybe that wasn’t the beginning.
One of the most common misconceptions about the Big Bang is that it implies that the entire universe was compressed into a single point, from which it then somehow expanded into the surrounding nothingness.
Experimental evidence doesn’t actually rule out the possibility that there may indeed be a time before the beginning, a previous age of the universe that ended when space collapsed in on itself … So physics might actually be nudging us back to the view that the universe is eternal and didn’t “begin” after all. (Which gives pause as to what is the beginning.)
