why is there a universe at all

It’s a big question, perhaps the biggest.

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.” 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. Around 13.7 billion years ago time and space spontaneously sprang from the void. The health benefits of sunlight: Can vitamin D help beat covid-19? The immune system: can you improve your immune age? 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." 6?�p�����vypG`����K�n9(q�5l��KW���WǺ����|�0\:���[Hw�5�pɋ��ȗ�����ʀ5����� �mh�>\��M#ƹ��, �vZ����4}}�����ꈿ _?�$ endstream endobj 38 0 obj <>stream 0��U�``�Jg3�0i2i3I3�30��}�`�ge` h�b```f``�f`a`ر������, L The Big Bang[edit] Main articles: Big Bang, Origin of the universe, and "Why is there anything at all? I believe they are both good questions. 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. 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. 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. Given this law, it is hard to see how nothing could …. ", 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. It is also a very reasonable question to ask from a scientific perspective. AS DOUGLAS ADAMS once wrote: “The universe is big. Should you avoid alcohol when getting a coronavirus vaccine?

Indeed, at one point it was non-existent. 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? And, even if reality cannot be fully explained, we may still make progress, since what is inexplicable may become less baffling than it now seems. Why Is There Something, Rather Than Nothing?

Why is there any matter in the universe at all? That is, why is there anything 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. here two questions: (1) Why does the Universe exist 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 space expanded, the universe cooled and matter formed. The second law of thermodynamics, that most existentially resonant of physical laws, says that disorder, or entropy, always tends to increase. The search for the origin of life: From panspermia to primordial soup. Scientists at the University of Sussex have measured a property of the neutron – a fundamental particle in the universe - more precisely than ever before. Modern physics suggests that the universe can exist all by itself as a self-contained system, without anything external to create or sustain it.

It seems natural to ask why the universe exists 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. Scientists at the University of Sussex have measured a property of the neutron – a fundamental particle in the universe – more precisely than ever before. 27 July, 2011. 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.

(2) Why is the Universe as it is? According to the hypothesis, the universe appears fine-tuned for intelligent life because of the anthropic principle, with most universes being devoid of life. THERE is plenty to recommend the standard model, our best description of particles and their interactions.But it has the odd awkward lapse. Why does anything exist at all? which could at least have partial answers. Really big.” And yet if our theory of the big bang is right, the universe was once a lot smaller.
