How did that happen? “Why is there something, rather than nothing?” could be the oldest and deepest question in all of metaphysics. Physicists and Cosmologists find themselves in a Quandary. p3�(�8S� � But there might not be an absolute answer to why it exists.

It is not clear that we can even speak coherently about the creation of the universe, given that such an event can be conceived only with reference to time, and here we are talking about the birth of space-time itself.” Many earlier thinkers had asked why our universe is the way it is, but Leibniz went a step further, wondering why there is a universe at all. 32 0 obj <> endobj 45 0 obj <>/Filter/FlateDecode/ID[<575C449AD0D9B941B269756155B14401>]/Index[32 18]/Info 31 0 R/Length 72/Prev 110770/Root 33 0 R/Size 50/Type/XRef/W[1 2 1]>>stream Why Is There Something, Rather Than Nothing?

In contrast, you can’t rearrange the molecules of a living thing very much without turning it into a non-living thing, so you are a low-entropy system. Modern physics suggests that the universe can exist all by itself as a self-contained system, without anything external to create or sustain it. ", I can never prove the above because I can never actually directly see whether the "absolute lack-of-all" is an existent entity, but what I can do is to use the above thinking to develop a model of the universe and eventually make testable predictions. I believe they are both good questions. Scientists at the University of Sussex have measured a property of the neutron—a fundamental particle in the universe—more precisely than ever before. Some dismiss these questions, thinking them idle. Entropy measures the number of ways you can rearrange a system’s components without changing its overall appearance.

One second after the Big Bang, the … The second law of thermodynamics, that most existentially resonant of physical laws, says that disorder, or entropy, always tends to increase. Scientists at the University of Sussex have measured a property of the neutron - a fundamental particle in the universe - more precisely than ever before. Why does anything exist at all? To investigate why all the antimatter created in the Big Bang didn't just cancel out the matter, the researchers have looked into whether or not the neutron acts like an "electric compass."
