How did that happen? 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.

The search for the origin of life: From panspermia to primordial soup. That is, why is there anything rather than nothing? Nor should we assume that answers to this question must be causal. Modern physics suggests that the universe can exist all by itself as a self-contained system, without anything external to create or sustain it. 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 I believe they are both good questions. which could at least have partial answers.

Some even think they make no sense. here two questions: (1) Why does the Universe exist at all? 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.

Physicists and Cosmologists find themselves in a Quandary. Science with Sam explains. %PDF-1.5 %���� Scientists at the University of Sussex have measured 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. ", 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. 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. It is also a very reasonable question to ask from a scientific perspective. Around 13.7 billion years ago time and space spontaneously sprang from the void.

Existence special: Cosmic mysteries, human 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." More logical, to me, is the bubbling, frothing multiverse situation—but okay, we still then have the same problem. 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. ;;���sO� 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. Scientists at the University of Sussex are measuring a property of the neutron—a fundamental particle in the universe—more precisely than ever before. After all, some basic physics suggests that you and the rest of the universe are overwhelmingly unlikely to exist. The idea that the universe simply appeared out of nothing is difficult enough; trying to conceive of nothingness is perhaps even harder.

According to the hypothesis, the universe appears fine-tuned for intelligent life because of the anthropic principle, with most universes being devoid of life.

But there might not be an absolute answer to why it exists. Or to put it another way: why does anything exist at all? Why is there any matter in the universe at all? Scientists at the University of Sussex have measured a property of the neutron - a fundamental particle in the universe - more precisely than ever before. AS DOUGLAS ADAMS once wrote: “The universe is big.

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. 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. “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. THERE is plenty to recommend the standard model, our best description of particles and their interactions.But it has the odd awkward lapse. Why Is There Something, Rather Than Nothing? Scientists at the University of Sussex have measured a property of the neutron – a fundamental particle in the universe – more precisely than ever before. 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. 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.
