Scientists at the University of Sussex have measured a property of the neutron - a fundamental particle in the universe - more precisely than ever before. Physicist Max Tegmark wrote about the mathematical universe hypothesis, which states that all mathematical structures exist physically, and the physical universe is one of these structures. I believe they are both good questions. 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." The molecules in a hot gas, for example, can be arranged in many different ways to create the same overall temperature and pressure, making the gas a high-entropy system. 27 July, 2011.

Scientists at the University of Sussex are measuring a property of the neutron—a fundamental particle in the universe—more precisely than ever before. According to NASA, after inflation the growth of the universe continued, but at a slower rate. Wherever they look, throughout all the Universe, or across the particles in their Accelerators, we keep finding tat it seems to be finely tuned to grant us our existence--specifically, Human existence. 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 Scientists at the University of Sussex have measured a property of the neutron -- a fundamental particle in the universe -- more precisely than ever before.

It’s a big question, perhaps the biggest. there is a Universe: why there is anything rather than nothing. Their research is part of an investigation into why there is matter left over in the universe, that is, why all the antimatter created in the Big Bang didn’t just cancel out the matter. Mystery: Why does anything exist at all? Modern physics suggests that the universe can exist all by itself as a self-contained system, without anything external to create or sustain it. To boot, Harris writes: “The truth is that no one knows how or why the universe came into being.

Their research is part of an investigation into why there is matter left over in the universe, that is, why all the antimatter created in the Big Bang didn't just cancel out the matter. If this universe is the only thing there is, that’s kind of weird and illogical—why would this big space just exist by itself in an otherwise nothing situation?

The second law of thermodynamics, that most existentially resonant of physical laws, says that disorder, or entropy, always tends to increase. As space expanded, the universe cooled and matter formed. Should you avoid alcohol when getting a coronavirus vaccine? “Why is there something, rather than nothing?” could be the oldest and deepest question in all of metaphysics.
