Further, the sheer existence of something means that everything (literally everything) that is possible must exist somewhere in the matrix of time, space and dimension. 0 comments. That's because every object in the universe creates gravity, pulling other objects toward it. Even the most perfect vacuum is actually filled by a roiling cloud of particles and antiparticles, which flare into existence and almost instantaneously fade back into nothingness. One thing they have found is that, when quantum theory is applied to space at the smallest possible scale, space itself becomes unstable. So which is it? Why does anything exist? Inflation theory proposes that in the immediate aftermath of the Big Bang, the universe expanded much faster than it did later. The universe next door might have five dimensions of space rather than the three – length, breadth and height – that ours does. By David Pearce. Here’s my view. Many would agree that things that exist must have an explanation; a reason why they are. By Mike Sygula, Is reincarnation real, do souls exist? Why Does the World Exist? We might want to know how we exist, which can be answered scientifically or with God, I don’t personally worry about that question either. 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 … Why does anything exist? These are some big questions that have been debated over and over for centuries. Actually your teachers left out a crucial point: this is only true on a flat surface. I know how much he stated about reasons why we should not exist such as Nirvana being the highest goal to escape from the karma bond!! hide. Without God creating, nothing would exist. So once inflation starts it should make an endless cascade of universes, which Linde calls eternal inflation. Bizarrely, this doesn’t seem to be the case. As Krauss puts it, "The laws of physics as we understand them make it eminently plausible that our universe arose from nothing - no space, no time, no particles, nothing that we now know of.". A solution to the question "Why is there something rather than nothing?" That's because only a flat universe is likely to have come from nothing. That's where inflation comes in. I know people are talking about the big bang and how it made space and all, but how and why did the big bang exist like big bang made everything we know, but who made the big bang. It could be as flat as a table top. It says that in the big bang, matter and antimatter should have been created in equal measure. Alternatively, if you draw a triangle on a surface that curves outward like a saddle, its angles will add up to less than 180 degrees. Why Does Anything Exist? This seemingly outlandish notion was put forward in the 1980s by Alan Guth at the Massachusetts Institute of Technology, and refined by Andrei Linde, now at Stanford University. Somehow, matter won. If they are right, our entire cosmos may have sprung out of nothing at all. “It would look very different, not least because planets and stars and life could not evolve in such an environment,” says Tara Shears at the University of Liverpool, UK. Why does anything at all exist?, Leibniz thought this to be the most basic question one can ask. The universe is flat and why that's important. Relativity is very different from quantum mechanics, and so far nobody has been able to combine the two seamlessly. So to find out if the universe is flat, we need to measure the angles of a really big triangle. In quantum physics, if something is not forbidden, it necessarily happens. Surely, even if a bubble formed, it would be doomed to disappear again in the blink of an eye? report. That inflating space can spawn more universes, with yet more inflating space around them. If one space-time bubble popped into existence and inflated to form our universe, what kept other bubbles from doing the same? The immune system: can you improve your immune age? But this is only true in a flat universe. Intuitively, there shouldn’t be anything to explain. These so-called virtual particles don't last long enough to be observed directly, but we know they exist by their effects. Log in or sign up to leave a comment Log In Sign Up. The old metaphysical question – why anything exists at all – has perplexed and intrigued humankind for ages. Should you avoid alcohol when getting a coronavirus vaccine? There could just be nothing, but instead there is something, and none of us truly know why. Anything of any kind, anywhere. In other words, little bubbles of space and time can form spontaneously. When the expansion finally slowed, the force field that had powered it was transformed into the matter and energy that fill the universe today. It uses sensible words and grammar and has the form of a question and so on. He thinks universes have always been springing into existence, and that this process will continue forever. 100% Upvoted. So how comes there’s something, not nothing? This follows from the discovery, in the early 20th century, that the universe is expanding. And, especially, why do we exist? Rather than remaining perfectly smooth and continuous, space and time destabilize, churning and frothing into a foam of space-time bubbles. The Big Bang theory is the prevailing theory about the “birth” of the universe. It had to happen, they say, because "nothing" is inherently unstable. Philosopher and author Jim Holt plays the role of the inquisitive detective who is on a mission to answer the ultimate question of existence. Alternatively, space-time could curve outward like a saddle. If someone believes in God, maybe they believe they will know why everything or anything existed when they die and join Him.
