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 … THERE is plenty to recommend the standard model, our best description of particles and their interactions.But it has the odd awkward lapse. It seems natural to ask why the universe exists at all. Some even think they make no sense. Indeed, at one point it was non-existent. Or to put it another way: why does anything exist at all? there is a Universe: why there is anything rather than nothing. �a����R�[2 �1�lCk�qS.�����&7\琣3�P�$�D0�����W�Ӓ�s��f�e^�qd�`�� ���^@���&-�f"y�Z�b�6�!~�xA\�[7�ϊ�|�1�yQҫ�v�r�y��M�1���i����(��PZ���2-�*"L�{%����\�E��̎#����h,��o���fAޚ��O�TWY���Dg �~@y5\ %PDF-1.5 %���� Why is there any matter in the universe at all? “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. 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. Some dismiss these questions, thinking them idle. Scientists at the University of Sussex are measuring a property of the neutron—a fundamental particle in the universe—more precisely than ever before.

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. p3�(�8S� � The idea that the universe simply appeared out of nothing is difficult enough; trying to conceive of nothingness is perhaps even harder. Like all proposed solutions to the question "Why is there something rather than nothing? New Sussex study sheds light February 28, 2020 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. At first all the matter and energy in the universe was crammed together in one … 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 … Mystery: Why does anything exist at all?

It is also a very reasonable question to ask from a scientific perspective. 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." 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 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.” The search for the origin of life: From panspermia to primordial soup.

Most physicists now think that the universe began with the Big Bang. 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. The second law of thermodynamics, that most existentially resonant of physical laws, says that disorder, or entropy, always tends to increase. Physicists and Cosmologists find themselves in a Quandary. 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. ;;���sO� Scientists at the University of Sussex have measured a property of the neutron – a fundamental particle in the universe — more precisely than ever before.
