Related: Black Hole Quiz: How Well Do You Know Nature's Weirdest Creations? So what is so special in it? Q: What is infinity? Black Holes are created as a result of the death of a large star. At a certain point, when a black hole becomes big enough, its interior forces can be low enough to avoid the matter to rip all apart. The debate went public in 1997, when Stephen Hawking and theoretical physicist Kip Thorne made a bet with John Preskill of Caltech that it would ultimately be shown that information was truly lost inside black holes. In videos circulating online, some people can be seen smoking and drinking beer, and a street cleaner carries on with sweeping litter. If the addition of antimatter makes the hole bigger, and thus stronger, then it doesent seem like anything other than Hawking Radiation COULD destroy it. What is the difference between batteries with the same voltage, but different shapes or sizes? And, as science writer Jennifer Ouelette So will we take this lying down? These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. Why is it that one random thing is unpredictable, but many random things together are predictable? Q: Is it possible to destroy a black hole? Q: Could a simple cup of coffee be heated by a hand held device designed to not only mix but heat the water through friction, and is that more efficient than heating on a stove and then mixing? No, the universe contains all solar systems, and galaxies. . For a black hole, any matter entering the event horizon is added to the mass. Over the past century, scientists have used Einstein . Its gravity would break. Number 1, its time to bring out the big guns. The big bang is a whole other thing. It will also consist of neutrons. Hawking went as far as saying black holes may not even exist. Will We Ever Create A Black Hole In The Laboratory? Scientists use satellites and telescopes in space to see the high-energy light. What happens at the edge? Then wouldnt they destroy each other (in the sense that they would destroy each others center, thus no longer having a mass to give them their unfathomable gravitational fields Without the matter that grants them their gravity, they would no longer exist would they? But doesnt something new need to be made up for the square root of i? Can space have a fractional dimension? Q: Whats that third hole in electrical outlets for?

Q: Is it possible to breach the center of a nebula? Theorists contented themselves with this view until 1975, when Stephen Hawking drew a revolutionary conclusion about black holes: Given enough time, a black hole will dematerialize,. By we I mean humans. Q: How far away is the edge of the universe? Q: Since the Earth is spinning and orbiting and whatnot, are we experiencing time wrong because of time dilation? According to National Aeronautics and Space Administration or NASA, a black hole is a place in space where gravity pulls so much that even light can not get out. Q: What is the best way to understand relativity theory? I think that Dejan is asking, if a matter blackhole (whos center, that gives it the tremendous gravity it has, is made of matter) collides with an anti-matter blackhole (whos center, that gives it the tremendous gravity it has, is made of antimatter). Q: What would happen if there was a giant straw connecting the Earths atmosphere right above the ground to space? Without fully understanding the complexities of the universe in all its wonders we will never be able to truly advance and ensure that humanity has the brightest future possible. Oh this is fun. Whats The Difference Between Asteroids, Comets, And Meteors? Since, in Euclidean space, straight lines that meet at infinity are parallel, all straight lines are in fact parallel (even though they dont seem to be), and we already live in a parallel universe. Or do we just have to close our eyes, avoid their gaze--and hope that they will they just fizzle out on their own. Wouldnt gravity be just a bi-product of what matter does to space? Q: Does quantum mechanics really say that theres some probability that objects will suddenly start moving or that things can suddenly shift to the other side of the universe? So, if by setting off a bomb you could change how rulers measure distance in a particular region of space, then you could affect a black hole. To protect the remaining postulate, they are willing to accept that something shocking might exist at the horizon: a firewall of broiling radiation that burns all that passes into a fiery crisp. Do primes follow a pattern? Magnetic and electric forces are definitely involved in the behavior of black holes! Q: Is there such a thing as half a derivative? Black holes are among the most destructive objects in the universe. However, you might wonder if, like other great galactic phenomena, they are only temporary. Hm. Q: According to relativity, two moving observers always see the other moving through time slower. The second is that someone falling into a black hole would experience nothing special at the event horizon. Whats the deal with this orders of operation business? Q: Is there some way to actually play quidditch? Q: How would the universe be different if = 3? Q: If youve got different amounts of debt in different accounts with different interest rates, how should you pay them down? Q: Why are the laws of quantum mechanics so strange? Power cannot be generated forever and since stars are required to generate their own source of energy then they can easily end up eating up all their energy in order to sustain themselves thus causing them to implode on themselves. A rocket moving away from Earth with constant speed of just 10 m/sec will eventually reach Moon orbit. On the downside, now you have a naked singularity, with all that that entails. When a black hole and a star are close together, high-energy light is made. This video was produced by TED-Ed, TEDs youth and education initiative. Q: Why does curved space-time cause gravity? Nominate yourself here . Q: Can you beat the uncertainty principle using entanglement, by measuring position on one particle and momentum on the other? The first two have since been completely confirmed, there is a lot of evidence for the existence of black holes (for example; Sagittarius A*, a tiny, invisible object with a mass in excess of four million Suns), and the last two are in the works.

(A brief introduction to infinite sets, infinite limits, and infinite numbers). And, according to Hawkings accounting, that radiation would be random, revealing nothing of the black holes contents. This, Many religious persons, including many scientists, hold that, Space is very, very cold. Stephen Hawking was like one of those unfortunate soldiers who wander in the jungle for years, not knowing that the hostilities have ended, wrote Susskind in The Black Hole War. But others found Hawkings explanation unsatisfying and, moreover, were irked at the public perception that one mans change of heart had truly settled a debate that was still actively raging in the physics community. Its possibly been converted into a regular flavour black hole. However, the stars that become Black Holes are far bigger. And can black holes with their immense destructive power themselves be destroyed? The black hole singularity would try to consume the white hole singularity and ultimately tie themselves into a knot of nonexistence. Without you this video would not be possible!

What if our Universe is simply a huge black hole? My bad: If atoms are mostly made up of empty space, why do things feel solid? Theoretically, you should reach a point where the inner and outer event horizons merge and then vanish. However, we can talk about black holes. How can you talk about chaos? Heck no! So, if by setting off a bomb you could change how rulers measure distance in a particular region of space, then you could affect a black hole. Send a ship with only droids to do the actual work. Artist's impression of a tidal disruption event which occurs when a star passes too close to a supermassive black hole. Where are they? Q: What is radioactivity and why is it sometimes dangerous? Q: Does an electric field have mass? Even though space can never truly demagnetize a magnet or weaken its powers the magnetic energy would have a LARGE area to exert itself eventually creating another black hole as it consumed and attracted other large pieces of energy.

March 4, 2014 by Fraser Cain How Do You Kill a Black Hole? What is its relevance? For example, if stuff falls into them, they get bigger. What about capacitors? In the unimaginably far future, cold stellar remnants known as black dwarfs will begin to explode in a spectacular series of supernovae, providing the final fireworks of all time. And does centrifugal force have an effect on gravity? Other uncategorized cookies are those that are being analyzed and have not been classified into a category as yet. I understand the part about how antimatter is mass, but I dont get how antimatter would just make a black hole bigger. The idea of a black hole - an object so massive that nothing could escape the grasp of its gravity - dates back to the 1700s. Q: Why doesnt life and evolution violate the second law of thermodynamics? Will it really be lost and gone forever? Q: How does instantaneous communication violate causality? It also means that information doesn't disappear. Black holes are one of the most fascinating yet mysterious objects in the universe.

Beyond the event horizon all directions point down (and thats messed up geometry). Q: What is the probability of an outcome after its already happened? It would get ripped apart before it could interact with matter (probably). Its a hole in space, a sink. What are we even looking at? Black holes are among the most destructive objects in the universe. Q: Hyperspace, warp drives, and faster than light travel: why not? Analytical cookies are used to understand how visitors interact with the website. Q: Why does Lorentz contraction only act in the direction of motion? Q: What are delayed choice experiments? Q: What would life be like in higher dimensions? How about a body that uses propulsion? Unlike a black hole, a white hole will allow light and matter to leave, but light and matter will not be able to enter. They are formed when a massive star dies and its gravitational pull becomes so strong that nothing, not even light, can escape it. Hawking calculated that the radiation would cause a black hole to lose energy, shrink and disappear, as described in his 1976 paper published in Physical Review D. Given his claims that the radiation emitted would be random and contain no information about what had fallen in, the black hole, upon its explosion, would erase loads of information. I believe that our universe is one of many all connected to each other by these black\white holes when the found evidence of a white hole in 2005 the reason it didnt appear to be caused by a supernova was because the supernova occurred in the opposing universe and made a black hole blowing time space and matter into our universe as white hole that is why they seemingly come out of nowhere. By some accounts, the universe may eventually consist entirely of black holes. Black holes- packets of space that contain a large amount of matter compacted into a small area- are one of the most amazing phenomena existent in our universe. Q: Why does curved space-time cause gravity? All energy has a maximum speed of the speed of light, and cannot travel any faster. Q: Why are orbits elliptical? Tell us what youre interested in and well send you talks tailored just for you. Time. Since light cannot escape, the event horizon is what makes a black hole black. Q: Is getting plasma really hot the only way to initiate fusion? Q: What makes natural logarithms natural? However, you may visit "Cookie Settings" to provide a controlled consent. What if I send a huge amount of electrons into black hole? Q: Why does kinetic energy increase as velocity squared? How Long Does It Take For A Star to Become A Black Hole? Go inside the information paradox with physicist Joe Polchinski, one of the authors of the paper that sparked the firewall controversy. if a black hole compresses all its matter to a single point does that mean a black hole could store an infinite mass? Perfectly microscopic, but definitely not infinitely tiny. I can assure you mine are still greater.. Q: Are beautiful, elegant or simple equations more likely to be true? In this study, singularity does not exist, and so it doesn't form an impenetrable barrier that ends up crushing whatever it encounters. This resistance to continued compression eventually forces the material to un-collapse (i.e., explode), making black holes only temporary objects. Performance cookies are used to understand and analyze the key performance indexes of the website which helps in delivering a better user experience for the visitors. So if you smash together a black hole and an anti-matter black hole (which is pretty much impossible since matter and anti-matter cant exist inside of a black hole) you would just get a black hole of twice the size. Join our Space Forums to keep talking space on the latest missions, night sky and more! Q: How do you prove that the spacetime interval is always the same? A team of physicists out of the University of California, Santa Barbara has shown that if information thrown into the black hole is conserved, one of two other unbreakable rules of physics must give out.
