Sentences with phrase «as a black hole spins»

One of the weirdest implications of Einstein's general relativity theory is that as a black hole spins, it pulls space - time along.

Not exact matches

The Advanced Laser Interferometer Gravitational - Wave Observatory's detection of spacetime ripples from two merging black holes on December 26, 2015, indicated that one black hole was spinning like a tilted top as it orbited with its companion (SN: 7/9/16, p. 8).

The accuracy of this assertion might become clearer in a few years, as various groups are running computer simulations to calculate the self - force of particles orbiting spinning black holes, says Barausse.

Likewise, if black holes act like information mirrors, as Hayden and Preskill suggested, a particle falling into a black hole would be followed by an antiparticle coming out — a partner with the opposite electric charge — which would carry the information contained in the spin of the original particle.

Until then, scientists regarded black holes as simple objects — quite literally holes in space, completely described by just three variables: their mass, spin and charge.

But that scenario should lead to black holes that spin in the same plane as their orbit.

Like bald pates, black holes of similar masses and spins then have no details — no «hair» — to distinguish them, as American theorist John Archibald Wheeler quipped.

But here is the real brainteaser: If the particle enters in the same direction as the black hole's spin, it joins an «outgoing beam» that has negative energy and moves backward in time.

In their latest finds, physicists with the Laser Interferometer Gravitational - Wave Observatory spotted the merger of black holes spinning in different orientations, as shown in this artist's conception.

«If the black holes were not spinning in the same direction as the orbit, that would probably be a pretty good indicator of the dynamical formation channel,» Rodriguez says.

If the black holes started out as paired stars, then they should spin in the same direction as their orbital axis.

The early 1970s were the «heroic age» of relativity research — theorists had proved that if Einstein was right, black holes weren't infinitely diverse but standardised objects, characterised just as surely as any elementary particle by mass and spin.

The concept is a variant of the Penrose process, first identified in 1969 by British astrophysicist Sir Roger Penrose as a mechanism for extracting energy from a spinning black hole.

Even if the star was rotating very slowly before it collapsed into a black hole, the collapsing material that ultimately forms the nascent hole must spin ever faster for the same reason whirling figure skaters accelerate as they pull in their arms.

Each time a merger occurred, material from the new galaxy got incorporated into the accretion disk around the black hole, spinning in the same direction as the black hole and eventually contributing to its growth.

As well as producing Oscar - nominated visual effects for the movie, Thorne and the effects team also unearthed some unexpected physics, such as that an observer close to a rapidly spinning black hole would see more than a dozen images of individual stars just outside one edge of the black hole's «shadow.&raquAs well as producing Oscar - nominated visual effects for the movie, Thorne and the effects team also unearthed some unexpected physics, such as that an observer close to a rapidly spinning black hole would see more than a dozen images of individual stars just outside one edge of the black hole's «shadow.&raquas producing Oscar - nominated visual effects for the movie, Thorne and the effects team also unearthed some unexpected physics, such as that an observer close to a rapidly spinning black hole would see more than a dozen images of individual stars just outside one edge of the black hole's «shadow.&raquas that an observer close to a rapidly spinning black hole would see more than a dozen images of individual stars just outside one edge of the black hole's «shadow.»

There maybe millions of such black holes floating around our own galaxy, eachfive or 10 times as massive as our sun and roughly 50 miles around, each spinning more or less furiously — once a millisecond or so would bepossible.

After all, it would require Alice to almost instantly measure the spin of a black hole as massive as the sun to within a single atom's spin.

It comes from the spinning space - time around the black hole and in fact it is not very well known, but that energy is there for the taking — up to 29 percent of the so - called rest mass energy of a spinning black hole is extractable — an d original conjecture, which is not, as I say [said], yet established fact, but certainly taken much more seriously than it was at that time — 10 or 15 percent of the rest mass energy of the black hole, about half of the spin energy, is in practice according to our conjecture, is in fact, the power source for these relativistically moving jets.

And if a black hole rotates, as would be the case for a hole that forms from the collapse of a spinning star, it drags spacetime along with it, a phenomenon known as frame dragging.

This rapidly spinning inner ring is clumpy and has streamers of matter jutting out of it toward the black hole, as if it is being devoured strand by strand.

«As matter falls into a black hole, it starts to spin and the rapid rotation pushes some fraction of the matter out,» Kaaret says.

Now, technically the earlier event, GW150914, also observed a Kerr black hole, as the final black hole after coalescence had spin (by conservation of angular momentum, since it was created from a pair of mutually - orbiting black holes).

This hybrid blazar idea implies that the luminosity of BL Lacs should decrease as their core black holes continue to lose energy and spin.

As matter is pulled toward a rotating black hole, it reaches an area where all must spin in roughly the same direction.

As pairs of black holes spiral together, heading towards a collision, they also spin on their own axes - like a pair of figure skaters spinning individually while also circling around each other.

It's tough to describe black - hole spin rates because they don't really translate into familiar terms, such as miles per hour.

«In our analysis, we can not measure the spins of the individual black holes very well, but we can tell if the black holes are generally spinning in the same direction as the orbital motion,» says astrophysicist Laura Cadonati, LIGO Scientific Collaboration deputy spokesperson from Georgia Tech.

Our results indicate that the event was probably caused by a rapidly spinning supermassive black hole as it destroyed a low - mass star,» Leloudas said in the statement Monday.

Also, additional wobbles in the signal are predicted as two spin - aligned black holes get close and begin to merge.
