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. The second law of thermodynamics, that most existentially resonant of physical laws, says that disorder, or entropy, always tends to increase.

By the same logic, nothingness is the highest entropy state around – you can shuffle it around all you want and it still looks like nothing. That is, why is there anything rather than nothing? The idea that the universe simply appeared out of nothing is difficult enough; trying to conceive of nothingness is perhaps even harder. “Why is there something, rather than nothing?” could be the oldest and deepest question in all of metaphysics. How did that happen? Gottfried Wilhelm Leibniz. 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. Why Is There Something, Rather Than Nothing? Some even think they make no sense.

William Barker, a doctoral student at the University of Cambridge, was searching for a theory of “modified gravity” last summer when he stumbled across a way to resolve the Hubble tension.Barker found a modified-gravity model that was “capable of behaving as if there were extra radiation in the early universe,” he said; the radiation pressure would have increased the cosmic … Scientists at the University of Sussex have measured a property of the neutron – a fundamental particle in the universe – more precisely than ever before.

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." “Inflation says there’s a multiverse, that there’s an infinite number of ways the Universe might come out, and we just happen to live in the one that is smooth and flat. Science with Sam explains.

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? That might indicate that there's more unobservable Universe beyond the part of our Universe we can access, but it doesn't prove it, and it doesn't provide evidence for a Multiverse. 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.

Modern physics suggests that the universe can exist all by itself as a self-contained system, without anything external to create or sustain it. Existence special: Cosmic mysteries, human questions.
