Most telescope mirrors are coated with aluminum. Space is not empty.A point in outer space is filled with gas, dust, a wind of charged particles from the stars, light from stars, cosmic rays, radiation left over from the Big Bang, gravity, electric and . When the migration is complete, you will access your Teams at stackoverflowteams.com, and they will no longer appear in the left sidebar on stackoverflow.com. A space that has zero particles, no particle at every place where a particle could be. How to dare to whistle or to hum in public? Since the big bang is an observational event horizon, we cannot talk about any events earlier, so one assumes that all the energy and matter has always been contained in your universe. What does 'levee' mean in the Three Musketeers? No, it isn't. It can only be redistributed throughout space and transformed into different states. People rose and slept with the light, relied on wood and dung burning for heat, and water power to generate basic mills. The densely compressed particle of pure energy that expanded into the universe, had no space to expand into. Keep in mind that mass is a positive form of energy, while interacting energy (like gravity) is a negative form of energy. There used to be a certain volume between the two surfaces when the matter was on the surface of area $5m^2.$. Ask a physicist about a vacuum, the very definition of nothingness for most of us, and they will tell you it is pulsing with activity. Something can be created from nothing But such a perfect vacuum may not exist. How will AIs that generate videos from text transform media online? In life, the human body comprises matter and energy. Is `0.0.0.0/1` a valid IP address? Under what conditions would a society be able to remain undetected in our current world? The best answers are voted up and rise to the top, Not the answer you're looking for? Why the difference between double and electric bass fingering? Does the dynamical Casimir effect generation of real photons create energy from nothing? Is it real? Energy is the ability to bring about change or to do work. Positive masses attract each other, but with a negative mass, gravity could suddenly become a repulsive force. Since the big bang is an observational event horizon, we cannot talk about any events earlier, so one assumes that all the energy and matter has always been contained in your universe. The Sun is the ultimate source of energy for most of life on Earth. Why did dinosaurs go extinct but not mammals? It can only be converted from one form or the other". Want to improve this question? Explanation: The total amount of energy within a system cannot change. Energy is never created or destroyed, it is always made available in one form converted from another, that you can then convert into another. This idea leads to some outlandish predictions. If so, what does it indicate? No machine can create energy out of nothing, as this would violate the law of mass-energy conservation, which is fundamental and universal. Connect and share knowledge within a single location that is structured and easy to search. No , time is not an Energy. Where does energy go when it is lost? We can turn light into subatomic particles, but even the best scientists can't create something out of nothing. First Law of Thermodynamics: Energy can be changed from one form to another, but it cannot be created or destroyed. So yes, the infalling matter has more energy now, but there is also more space. The conservation of energy is an absolute law, and yet it seems to fly in the face of things we observe every day. The only way to apparently create energy is in a nuclear reaction, when a tiny amount of mass is converted to energy. The law of conservation of energy states that energy can neither be created nor destroyed. How can I make combination weapons widespread in my world. This means that a system always has the same amount of energy, unless it's added from the outside. It's a subtle question. What does the drill site tell scientists? What keeps mass from turning into energy? Can energy be created from nothing? Is it possible to stretch your triceps without stopping or riding hands-free? Generally it requires energy. Is energy conserved when things fall into a black hole? When the migration is complete, you will access your Teams at stackoverflowteams.com, and they will no longer appear in the left sidebar on stackoverflow.com.

How can I make combination weapons widespread in my world? Since the big bang is an observational event horizon, we cannot talk about any events earlier, so one assumes that all the energy and matter has always been contained in your universe. The law of conservation of energy, also known as the first law of thermodynamics, states that the energy of a closed system must remain constantit can neither increase nor decrease without interference from outside. Thermodynamics is the study of energy. Energy came from nothing as many scientists know. Calculate difference between dates in hours with closest conditioned rows per group in R. Is `0.0.0.0/1` a valid IP address? Bezier circle curve can't be manipulated? IT DEPENDS what you mean by nothing. Constant fluctuations in energy can spontaneously create mass not just out of thin air, but out of absolutely nothing at all.. Is empty space really empty? When the universe began the vacuum of space did not exist. Energy is conserved except in General Relativity, and even then energy density obeys a differential conservation law so really it is more about the relationship between energy and energy density and that relationship determined by geometry. [6] Something can be created from nothing But such a perfect vacuum may not exist. Stack Exchange network consists of 182 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. So now, we cannot create energy. Physicists think the Big Bang did. Physicists call this the 'vacuum state,' and thanks to quantum mechanics, it has some weird properties. The energy in the atoms came from the nuclear reactions in the heart of the Sun. Is it bad to finish your talk early at conferences? The rest we call antimatter, except for some that are their own antiparticles where we don't bother to call them either. D. The total amount of energy in a system changes continuously. The short answer is no. The idea of inflation could also explain why there is so much matter in the universe.The answer is that, in quantum theory, particles can be created out of energy in the form of particle/antiparticle pairs. IT DEPENDS what you mean by nothing. Can work be created or destroyed? If yes, what sort of matter is produced? Since the big bang is an observational event horizon, we cannot talk about any events earlier, so one assumes that all the energy and matter has always been contained in your universe. All I'm saying is that maybe the anti-matter caused some kind of energy transfer that is completely new to us. Nothing is to be regarded as $0$ energy, $0$ mass, $0$ charge, and so on. Can you create mass from nothing? I understand your reasoning but say there was really nothing before the big bang, then something must have come from that. How can a retail investor check whether a cryptocurrency exchange is safe to use? So now, we cannot create energy. Specifically, imagine a shell of surface area $5m^2$ with some matter on it that then compresses to a smaller more compact shell of surface area of $4m^2$ with the same matter on it. In 1948, the physicist Hendrik Casimir proposed that if you place two parallel metal plates close to each other in a vacuum, there will be more quantum electromagnetic fluctuations either side of the plates than between them. Start a research project with a student in my class. So now, we cannot create energy. The town of Oymyakon in Siberia is the coldest permanently, A marsquake is a quake which, much like an earthquake, Pale Blue Dot is a photograph of planet Earth taken, The data collected by the drill telling it how to operate, It looks like a modest orange star. Matter has energy, so you must either create energy or take energy from something else. Share: 0 comments. The short answer is no. Originally Answered: Is time a form of energy? What does the law of conservation of energy state? Its a weakling force but it has been detected. How are antimatter and antiparticle related to the issue? In quantum mechanics, nothingness is not really nothing. The conservation of energy in all processes in our universe is rooted mathematically in the fact that the laws of nature do not change with time. [closed]. "Energy can neither be created nor destroyed. So particle-antiparticle pairs can be created from "nothing", that is from no particles to two particles, but energy must be provided, so these particles can be viewed as having been created from the energy. In order to contemplate the universe creating itself from nothing, you must first accept the proposition that something can be created from nothing.That is tenable only in the quantum realm, so applying it to the universe presumes a quantum scale for the universe. So, to answer your question, energy cannot be "created" from nothing ! Electrically charged matter can be produced in equal numbers of particle and antiparticle. Energy didn't come "from nothing . By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. Can you create energy from nothing Why or why not? Why don't chess engines take into account the time left by each player? Even if the matter is somewhat more complicated than previously thought, energy cannot be obtained from nothing, even though it can become negative. We now have a machine powerful enough to tear it apart and see, Something is tearing everything apart even faster than we thought and not even atoms will survive, never mind our picture of how the universe evolved, it is possible to use the effect to release latent energy, by using rapidly changing electrical currents to simulate the effect of minuscule mirrors whooshing together at a quarter of the speed of , Roger Penrose: "Consciousness must be beyond computable physics", Feeding cows hemp makes them high and their milk could be unsafe, Secretive US space plane X-37B lands after record 908 days in orbit, Drought, not lithium mining, is drying out Chile's largest salt flat, We now know why some poos float and others sink, Crucial Congo rainforest faces growing threats from logging and mining, Pre-eclampsia may raise a fetus's risk of heart disease in later life, Leprosy bacteria may hold the key to helping the liver regenerate.

Browse other questions tagged, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site, Learn more about Stack Overflow the company. Energy didn't come "from nothing". So the short answer is that the energy we encounter and use everyday has always been with us since the beginning of the universe and always will be with us. Quantum theory, however, allows negative energy. Energy is the ability to bring about change or to do work. This means that a system always has the same amount of energy, unless it's added from the outside. What can we make barrels from if not wood or metal? One of the presumptions of The Grand Design is that the universe creates itself.. The first source of energy was the sun, as it provided heat and light during the day. According to the law of conservation of energy, energy can neither be created nor destroyed; rather, it transforms from one form to another. The new particles would require some energy and that has to be created or come from something. And more recently, physicists like Chris Wilson, now at the University of Waterloo in Canada, have tried to prove another eccentric prediction: that it is possible to use the effect to release latent energy. Name Email Can matter be created in a pure vacuum (with no energy)? My PhD fellowship for spring semester has already been paid to me. The short answer is no. Stack Overflow for Teams is moving to its own domain! But that just raises the question of where the energy came from. So now, we cannot create energy. Can energy be created from nothing? Are we mostly nothing? The energy from one particle can be given to another (possibly new) particle that interacts with it, via the interaction. Want to improve this question? https://xphysics.wordpress.com/2011/02/11/spontaneous-creation-of-matter-and-antimatter/. Can something be created from nothing? There is a hypothetical effect called the Unruh effect where a particle detector in a vacuum can detect particles if it is accelerating. If I drop out mid-semester, what is the likelihood that I'll have to pay it back? Energy didn't come "from nothing". Matter and antimatter are made equally, for every particle made, the antiparticle of that particle is also made. And then latter when the same matter is on the surface of surface area of $4m^2$ the curvature between the two surfaces is different and now has more volume between the surfaces. 4 Lawrence C. When I was young I had a set of gears and axles to play with (an Erector Set). Time, space, and matter were all created simultaneously. Can energy be lost? So in 2011 Wilson and his colleagues tested the dynamical Casimir effect, as its known, by using rapidly changing electrical currents to simulate the effect of minuscule mirrors whooshing together at a quarter of the speed of . It can only be transformed from one form to another. I do find it interesting. No. Why would an Airbnb host ask me to cancel my request to book their Airbnb, instead of declining that request themselves? Is it possible all matter in the universe emerges from nothing? The short answer is no. The zero-energy universe hypothesis states that the amount of energy in the universe minus the amount of gravity is exactly zero. The energy had to be in other particles so those particles will have to give up their energy. If the energy is created then you need to create space and that requires some matter if you want to connect that space to our space. The whole universe can be created from nothing. What started the nuclear reactions? Connect and share knowledge within a single location that is structured and easy to search. [These all questions popped up in my mind when I was reading Dan Brown's Angels and Demons]. the nothingness stores the energy and then it condensed due to space-time until the big bang happened because of it becoming too big and imploding. @KyleKanos Boon that's easy enough to see, now that you tell me, ordinary matter = boon, dark matter= Bane = poison, kind of makes cosmological sense, sort of, thanks, Can matter be formed from nothing? Add details and clarify the problem by editing this post. Antimatter isn't different than matter, we just call the particles we see every day matter and also the ones most similarly related (either similar by color charge for quarks, or similar by electric charge for charged leptons or by how they interact with charged leptons if uncharged leptons). Is the portrayal of people of color in Enola Holmes movies historically accurate? The law of mass-energy conservation states that mass-energy can never be created or destroyed. What can we make barrels from if not wood or metal? "According to quantum physics, it is possible to borrow energy from a vacuum at a certain location, like money from a bank," says Daniel Grumiller. Can we prosecute a person who confesses but there is no hard evidence? Physics Stack Exchange is a question and answer site for active researchers, academics and students of physics. . Energy in one form can only be transformed into another form. How did knights who required glasses to see survive on the battlefield? Another example I didn't mention before is hypothetical, which is Hawking radiation. The vacuum state is a state of lowest energy. The short answer is no. The law of mass-energy conservation states that mass-energy can never be created or destroyed. *Cancel anytime within 14 days of payment to receive a refund on unserved issues. What was the first source of energy? In the late 1960s, physicist Andrei Sakharov identified three conditions necessary for baryogenesis, or the creation of more baryons (protons and neutrons) than anti-baryons. Boon or bane. Google Maps Now Lets You Explore Mars And The Moon, Around 66 million years ago, at the end of the Cretaceous. Stack Overflow for Teams is moving to its own domain! Thomas Young (1773 1829) first introduced the word energy to the field of physics in 1800, but the word did not gain popularity. Thomas Young later established the wave nature of light through interference experiments. The phenomenon became known as the Casimir effect. Firstly, how do we know whether there is energy? If a big gear engages and drives a smaller gear, then the smaller gear turns faster. Is it possible all matter in the universe emerges from nothing? Mars also has an. rev2022.11.15.43034.
