Sentences with phrase «energy out of a black hole»

And the reason you can get energy out of a black hole, that swallower of all things, is that the energy you detect never really got into the black hole to begin with — it's associated with the space - time whirlpool created outside the event horizon by the black hole's rotation.

The new mechanism for getting energy out of a black hole is not actually new.

Let's say some future civilization wanted to get energy out of a black hole.

Not exact matches

For comparison, the collision detected in September created a black hole with the equivalent of 62 solar masses, blasting out 50 times more energy than all the stars in the universe combined.

Sorry charlie, we already know that laws of nature are thrown out in cosmic explosions, black holes and can theorize that just because we now have the law of the conservation of energy doesn't mean that it applied 14 billion years ago.

Taken with the orbiting Chandra Observatory, it shows the hottest, most violent objects in the galaxy: black holes gobbling down matter, gas heated to millions of degrees by dense, whirling neutron stars, and the high - energy radiation from stars that have exploded, sending out vast amounts of material that slam into surrounding gas, creating shock waves that heat the gas tremendously, generating X-rays.

The Nottingham experiment was based on the theory that an area immediately outside the event horizon of a rotating black hole — a black hole's gravitational point of no return — will be dragged round by the rotation and any wave that enters this region, but does not stray past the event horizon, should be deflected and come out with more energy than it carried on the way in — an effect known as superradiance.

«It's very tricky telling what's the feature and what's the continuum,» says Julian Krolik of Johns Hopkins University, one of the theorists now trying to figure out how magnetic fields could convert a black hole's spin energy into light.

The information would basically remain encoded in an infinite number of low - energy photons racing to get out of the black hole, but stuck at its event horizon by the black hole's intense gravity, according to a study in Physical Review Letters.

How much material do high - energy objects, like exploding stars or ravenous black holes, toss out of their galaxy's gravitational grip?

The stellar nursery surrounds a supermassive black hole that pours out enormous amounts of energy.

a) A tangled ball of cosmic string b) A being that appears to be made out of pure energy, captain c) A bubble of space that inflated out of sync with the rest of the universe d) A giant black hole whose gravity red - shifts light from that direction

This condition maintains that any real observer can only measure positive rather than negative energy, ruling out the types of theoretical time machines that involve travelling through black holes held open by exotic material with negative energy.

The most powerful jets, called quasars, arise when black holes weighing as much as billions of suns fling infalling matter and energy back out into the galaxy, heating up loads of dust and gas and creating blinding beams of energy.

«It «svery tricky telling what's the feature and what's the continuum,» saysJulian Krolik of Johns Hopkins University, one of the theorists nowtrying to figure out how magnetic fields could convert a black hole «sspin energy into light.

The star's gas has been falling into the black hole, causing enormous amounts of energy to be released in the form of high - energy particles shooting out like a jet.

The process could be driving vast amounts of gas and dust toward the coalescing black hole, in turn causing intense energy to billow out from the object, says Neil Gehrels, a physicist at NASA's Goddard Space Flight Center in Greenbelt, Maryland, and a member of the research team.

In rare cases, black hole births are even more spectacular, with the star firing out powerful jets of high - energy radiation as it dies — a phenomenon known as a gamma - ray burst.

Discovering that it was possible to take energy quickly out of a black hole would be problematic for our understanding of how matter behaves around the event horizon.

This black hole blasts out prodigious amounts of energy as it feeds on the material in its accretion disk.

However, their black holes are quiet — they're not putting out the large amounts of energy we see in this one.

Astronomers have found a relatively tiny galaxy whose black - hole - powered central engine is pouring out energy at a rate equal to that of much larger galaxies, and they're wondering how it manages to do so.

The first black holes in the universe had dramatic effects on their surroundings despite the fact that they were small and grew very slowly, according to recent supercomputer simulations carried out by astrophysicists Marcelo Alvarez and Tom Abel of the Kavli Institute for Particle Astrophysics and Cosmology, jointly located at the Department of Energy's SLAC National Accelerator Laboratory and Stanford University, and John Wise, formerly of KIPAC and now of NASA Goddard Space Flight Center.

To date, NASA's Chandra mission has managed to pinpoint many of the individual black holes contributing to the X-ray background, but the ones that let out high - energy X-rays — those with the highest - pitched «voices» — have remained elusive.

New data from NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, has, for the first time, begun to pinpoint large numbers of the black holes sending out the high - energy X-rays.

Indian scientists made direct contributions — ranging from designing algorithms used to analyse signals registered by detectors to ascertain those from a gravitational wave to working out parameters like estimating energy and power radiated during merger, orbital eccentricity and estimating the mass and spin of the final black hole and so on.

Fuqua has a lot of fun playing with the clichés / tropes of westerns and succeeds in producing a fun movie that is most notable for having a uniquely integrated Seven — and least notable for having a villain who is an unmodulated black hole of evil that sucks the energy out of almost every scene he's in.
