Scientists just spotted 2 black holes flirting and dancing like awkward middle schoolers 

  • Astronomers have detected a pair of supermassive black holes 750 million light-years away from Earth in a separate giant galaxy.
  • Courtesy of the National Science Foundation’s Very Long Baseline Array’s (VLBA) radio vision data on the orbital motion of the black holes has been captured.
  • Together, the two black holes have a combined mass that is 15 billion times the mass of the Sun, which is 1.989 x 10^30 kilograms or 330,000 times the mass of Earth.
  • But most galaxies have supermassive black holes that are millions or billions times larger than the Sun at their core.
  • What makes these two black holes unique is their distance from one another: They’re relatively close to each other with only 24 light-years of distance between them. Read more (6/28/17)

Black holes do not “suck,” they pull via gravity, like the earth and the sun. They aren’t vacuum cleaners and “sucking” is the wrong word to use. They pull things in. 

also, if the sun were to suddenly collapse into a black hole, nothing would change since the sun’s mass would equal the black hole’s mass. the earth and all the other planets would continue to orbit, except they’d be orbiting a sun-mass black hole instead. 

Thank you for your time.

Scientists say there could be tens of millions of black holes in our own galaxy

  • There may be as many as 100 million black holes in the Milky Way alone.
  • That’s according to a new paper published in Monthly Notices of the Royal Astronomical Society.
  • The paper was inspired by the findings from a pair of devices known as the Laser Interferometer Gravitational-Wave Observatory.
  • In less than two years, LIGO has eavesdropped three times on the chirp that signals two gigantic black holes merging.
  • In each case, the black holes involved boasted about 30 suns’ worth of mass. Read more (8/9/17)

What we don’t know about black holes:

Of all the places in the entire universe, there is probably nowhere more mysterious than the inner workings of a black hole. This is because the two most accurate theories humans have ever created disagree about what happens in the center of one.

When a large star runs out of fuel, it no longer has the energy to resist its own gravity and starts pulling in on itself. If nothing stops the collapse before a certain point, the gravity will become so strong that not even light can escape. At this point, the star becomes a black hole; a massive celestial body that has the ability to tear apart stars.

For the most part, we have a good idea for what happens in the space around a black hole. Einstein’s theory of General Relativity tells us that black holes, as well as other massive objects, bend the fabric of space and time, leading to strange events such as time dilation. But the main point of controversy isn’t what happens around a black hole, but what happens in the very middle; the singularity.

General Relativity states that if a piece of matter falls into a black hole, it gets crushed into a single point in the center. Here, any information about what fell in is completely obliterated. However, quantum mechanics tells a different story. It is a well known rule in quantum physics that quantum information can’t be destroyed, and there must be some ambiguity to a particle’s position. Clearly, something is off here.

There are a lot of different theories that attempt to solve this riddle, often involving extra dimensions or new particles beyond the Standard Model, but none of them seem to be currently testable. But it’s possible that someday, someone will give us a new, testable theory, and it will give us insight into the inner working of black holes, and maybe even the first few moments of the Big Bang.

Black holes are a passage to another universe, says Stephen Hawking
Humans could escape from black holes, rather than getting stuck in them, according to a new theory proposed by Stephen Hawking.

Unfortunate space travellers won’t be able to return to their own universe, according to Hawking. But they will be able to escape somewhere else, he has proposed at a conference in Stockholm.

Black holes in fact aren’t as “black” as people thought and could be a way of getting through to an alternative universe.

“The existence of alternative histories with black holes suggests this might be possible,” Hawking said, according to a report from Stockholm University. “The hole would need to be large and if it was rotating it might have a passage to another universe. But you couldn’t come back to our universe. So although I’m keen on space flight, I’m not going to try that.

Hawking’s proposal is an attempt to answer a problem that has tormented physicists about what happens to things when they go beyond the event horizon, where even light can’t get back. The information about the object has to be preserved, scientists believe, even if the thing itself is swallowed up — and that paradox has puzzled scientists for decades.

Now Hawking has proposed that the information is stored on the boundary, at the event horizon. That means that it never makes its way into the black hole, and so never needs to make its way out again either.

That would also mean that humans might not disappear if they fall into one. They’d either stay as a “hologram” on the edge, or fall out somewhere else.

“If you feel you are in a black hole, don’t give up,” he told the audience at the end of his speech. “There’s a way out.”


Finally! Hawking finally said it! YES!

unstablestar  asked:

Can black holes die? if not, then is it possible for black holes to continue merging and expanding until all matter in the universe is pulled into one big massive black hole? if black holes can die then what happens with the matter that has been pulled in by the gravitational force? would a white hole then be produced after the black hole dies?

Black holes can, in fact, die! The way they die, however, is theoretical and not proven, but it’s possible and it’s called Hawking radiation. To summarize // oversimplify (because it’s really complicated), according to quantum physics we know that particle-antiparticle pairs pop in and out of existence all the time, and usually annihilate each other almost immediately. They are able to come into existence by “borrowing” energy from the universe, and when they annihilate they “return” that energy back.

Now, what if a particle-antiparticle pair comes into being right at the edge of a black hole’s event horizon, and one particle falls in and the other escapes? Well, now you’ve just “created” one particle that’s entered the universe, and one particle that’s entered the black hole (and can’t escape). Since these two particles can’t annihilate, they can’t “return” their borrowed energy to the universe. However, you can’t just spontaneously create energy; it has to come from somewhere. That somewhere is, you guessed it, the black hole. So, the amount of energy in the black hole decreases by the amount of energy required to create the particle-antiparticle pair. Since mass and energy are equivalent (e=mc2), the mass of the black hole decreases ever so slightly - the mass of an electron, positron, or other subatomic particle. 

This process takes billions of years, and it will be another several billion years before we’re able to see black holes finish evaporating. This process is expected to be faster the smaller the black hole is - once a black hole is small enough, this process happens faster and faster, until the black hole gives off lots and lots of radiation and “explodes” (think: gamma rays, really bright, as bright or brighter than a supernova), and no longer exists. While this isn’t proven and is entirely theoretical, it’s pretty cool that black holes, the killers of the universe from which nothing should be able to escape, are slowly losing mass over billions and trillions of years, one subatomic mass at a time.

There is sound in space, thanks to gravitational waves

“These waves are maddeningly weak, and their effects on the objects in spacetime are stupendously tiny. But if you know how to listen for them — just as the components of a radio know how to listen for those long-frequency light waves — you can detect these signals and hear them just as you’d hear any other sound. With an amplitude and a frequency, they’re no different from any other wave.”

You’ve likely heard that there’s no sound in space; that sound needs a medium to travel through, and in the vacuum of space, there is none. That’s true… up to a point. If you were only a few light years away from a star, stellar remnant, black hole, or even a supernova, you’d have no way to hear, feel, or otherwise directly measure the pressure waves from those objects. But they emit another kind of wave that can be interpreted as sounds, if you listen correctly: gravitational waves. These waves are so powerful, that in the very first event we ever detected, the black hole-black hole merger we saw outshone, in terms of energy, all of the stars in the observable Universe combined. There really is sound in space, as long as you know how to listen for it properly.

Come learn about it, and catch a live event, live-blogged by me, this evening!

harrlson-wells  asked:

Follow up question, are black holes funnel shapes? And if so why?

I’m guessing you’re referring to images like this, which show black holes to appear funnel shaped

To summarize, objects warp space and time. To make it easier to imagine, representations are taken down to two dimensions, so you can see how an object warps space and time. The more massive the object, the more it warps time. Black holes theoretically warp space and time infinitely at the singularity (where any amount of matter can be compacted, in some cases millions of suns). 

The black hole appears funnel-shaped because the curvature of space increases as you approach the black hole, and then becomes infinitely curved and infinitely steep when you reach the singularity. It’s misleading, but it does help visualize how they warp space. Black holes in reality are spherical, as they warp space in all directions (that’s why these images take it down a dimension to make visualization infinitely easier). 

I hope I did a good job with this - it can be pretty hard to wrap your head around it, let me know if you have any other questions.
