We already know that particles spring into existence at the quantum level, so we might expect the universe to contain a few odds and ends. Science with Sam explains. Yet the conjecture can be experimentally refuted. At this point, making a universe looks almost easy. If all of nature, space, and time have a cause, that cause cannot be natural, spacial, or temporal, for the same reason that a man cannot be his own father. which could at least is an intellectual quest of one the most intriguing philosophical questions, "Why Does the World Exist". 0 comments. However, in recent years a few physicists and cosmologists have started to tackle it. Why is there something rather than nothing? Quantum mechanics tells us that "nothing" is inherently unstable, so the initial leap from nothing to something may have been inevitable. At first all the matter and energy in the universe was crammed together in one unimaginably small dot, and this exploded. View image of (Credit: NASA, ESA, M.

Loll (ASU)). Without God creating, nothing would exist. Actually, it’s worse than that: the standard model positively insists we don’t exist. Bizarrely, it may not have had to get any. The ancient Greek philosopher Aristotle argued that everything must have a cause, culminating in an ultimate uncaused cause. For instance, this approach was used by Stephen Hawking at the University of Cambridge to describe black holes. Actually, it is possible for the bubble to survive. So to find out if the universe is flat, we need to measure the angles of a really big triangle. People have wrestled with the mystery of why the universe exists for thousands of years. That's because only a flat universe is likely to have come from nothing. You can take the number 1 (“All That Is,” so to speak) and divided it down into infinitesimally smaller parts. It uses sensible words and grammar and has the form of a question and so on. The basic reason that “anything” exists is that shortly after the initial diffusion of the “Big Bang”, the Higgs field allowed the newly-formed subatomic particles to have mass. So it's not just particles and antiparticles that can snap in and out of nothingness: bubbles of space-time can do the same. hide. Inside the fight to save the Great Barrier Reef from climate change, Meteorites may have brought water to Earth in the recent past, Videos of over 200 science talks plus weekly crosswords available exclusively to subscribers, Exclusive access to subscriber-only events. Why Does the World Exist? Existing subscribers, please log in with your email address to link your account access. There is the complexity of evolution and all kinds of things to talk about in this macro world if we wanted but it doesn’t explain anything why this macro world came to exist. When the expansion finally slowed, the force field that had powered it was transformed into the matter and energy that fill the universe today. Posted on November 18, 2015 by algekalipso . Consider the universe—by which I mean everything that has existed, does exist, and will exist. So how comes there’s something, not nothing? Their admittedly controversial answer is that the entire universe, from the fireball of … Surely, even if a bubble formed, it would be doomed to disappear again in the blink of an eye? 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.". Log in or sign up to leave a comment Log In Sign Up. 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. If the universe had been curved, the two sums would not cancel out. Here’s my view. You might remember from maths class that the three angles of a triangle add up to exactly 180 degrees. There could just be nothing, but instead there is something, and none of us truly know why. Everything that exists. the respond is not any. THERE is plenty to recommend the standard model, our best description of particles and their interactions. First we have to take a look at the realm of quantum mechanics. In other words: Why does the universe exist (and why are we in it)? Thus, the fact that anything should exist at all demands an explanation. So there could be a mind-boggling smorgasbord of universes. Intuitively, there shouldn’t be anything to explain. In quantum physics, if something is not forbidden, it necessarily happens. This is the branch of physics that deals with very small things: atoms and even tinier particles. What I Learned From … Growing up in northern California, I spent a lot of … In an incredibly brief moment, it went from being smaller than the nucleus of an atom to the size of a grain of sand. 100% Upvoted. “It is a somewhat embarrassing fact that it fails to explain our existence,” says Werner Rodejohann at the Max Planck Institute for Nuclear Physics in Germany. One thing they have found is that, when quantum theory is applied to space at the smallest possible scale, space itself becomes unstable. If one space-time bubble popped into existence and inflated to form our universe, what kept other bubbles from doing the same? These two famously don’t get along, annihilating one another in a flash of light whenever they come within touching distance. This balances the energy needed to create the matter in the first place. Since the existence of anything requires a cause, this is the proper way to ask the question: Why does anything exist? Some physicists think they can explain why the universe first formed. That's where inflation comes in. Nothing doesn’t result in something. in certainty, scientists have faith dark count number makes up a lot extra of the universe than seen count number does, which in part explains why gravity exists in places the place there ought to be none. Philosopher and writer Jim Holt follows this question toward three … It's a bit like an old-fashioned measuring scale. But for that we need another trick: cosmic inflation. In that case, there should be …. Those patches were measured in 2003, and that gave astronomers a selection of triangles. Gravity might be ten times stronger or a thousand times weaker, or not exist at all. Nothing and something are opposing ends of the same coin toss. This idea may sound bizarre, or just another fanciful creation story. Answer: When someone asks why is there Something rather than Nothing, they are asking for the cause of Existence in the widest possible sense—for the cause of everything. One possibility is that the antimatter is just hiding: some of it, somehow, escaped the death match, taking refuge in little safe spots that eventually became distant regions as the cosmos cooled and expanded. If the universe had not expanded so rapidly, we would expect the radiation to be patchier than it is. Why does anything exist? The question "Why is there anything at all? (2) Why is the Universe as it is? Climate change: 2020 was the joint hottest year on record, Covid-19 news: Major incident declared in London as virus cases surge, CRISPR doubles lifespan of mice with rapid ageing disease progeria, Corals bleached from heat become less resilient to ocean acidification, Black holes leak energy when they eat plasma near the event horizon, UK may allow gene editing of crops and livestock following Brexit, Plants that suck metals from the soil can be farmed to make our tech, The scientific guide to a better Christmas dinner, How do mRNA coronavirus vaccines work? That information, they say, should give us a clue about how and why the cosmos exists. Some dismiss these questions, thinking them idle. But it has the odd awkward lapse. It could be as flat as a table top. The old metaphysical question – why anything exists at all – has perplexed and intrigued humankind for ages. Einstein's theory of general relativity tells us that the space-time we live in could take three different forms. Linde says eternal inflation is not just the ultimate free lunch: it is the only one at which all possible dishes are available. What's more, if it's possible for these bubbles to form, you can guarantee that they will. When a new universe stops inflating, says Linde, it is still surrounded by space that is continuing to inflate. Just like to know for balance of reality. Then the resulting tiny bubble of space-time could have burgeoned into a massive, busy universe, thanks to inflation. One of the most remarkable things is that the scale of the universe compared to our size is equal to the scale of the universe of us to the micro world. There is a way to tell. They should have snuffed each other out in a hot orgy of mutual destruction during the first second of the universe’s existence, leaving a cosmos filled with nothing but light. The Big Bang theory is the prevailing theory about the “birth” of the universe. Philosopher and author Jim Holt plays the role of the inquisitive detective who is on a mission to answer the ultimate question of existence. Sign up to read our regular email newsletters. These so-called virtual particles don't last long enough to be observed directly, but we know they exist by their effects. 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!! His argument summarizes and ends up concluding that God is the reason. 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 … In brief, I propose that a thing exists if it is a grouping . There could be a mind-boggling smorgasbord of universes. It is an immensely successful theory, and it underpins most modern electronic gadgets. As weird as it seems, inflation fits the facts rather well. In other words, little bubbles of space and time can form spontaneously. Some even think they make no sense. Physicists have calculated that in a flat universe the energy of matter is exactly balanced by the energy of the gravity the mass creates. 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. share. But the physicists argue that it follows naturally from science's two most powerful and successful theories: quantum mechanics and general relativity. Rather than remaining perfectly smooth and continuous, space and time destabilize, churning and frothing into a foam of space-time bubbles. So once inflation starts it should make an endless cascade of universes, which Linde calls eternal inflation. "If space and time are quantized, they can fluctuate," says Lawrence Krauss at Arizona State University in Tempe. Most physicists now think that the universe began with the Big Bang.
