Black Holes

Scientists proposed new idea. They think that primordial gas in the very early universe directly collapsed into small black holes. And these black holes can grow into a supermassive black hole in only millions of years. Black holes on steroids ... how sweet

Unexpected 'storm' in the 'Teacup'

150211101927-large.jpg


A supermassive black hole is explosively heating and blasting around the gas [accelerated to speeds up to ~1000 km/s] in the Teacup galaxy [located ~ 1.1 billion ly from us] and, as a result, is transforming it from an actively star-forming galaxy into one devoid of gas that can no longer form stars. Observations showed that the galaxy has "bubbles" extending from 30000 to 40000 ly on each side of its core, along with smaller jet-like structures ~2000 ly in size.


Black hole growth may precede the growth of bulges in some galaxies

Hen 2-10 is a dwarf starburst galaxy ~ 30 million ly from us. A black hole at its center has a mass about one million times that of the Sun. Since Hen 2-10 does not contain a significant bulge of stars in its center, these results show that supermassive black hole growth may precede the growth of bulges in galaxies.

I think now is an opportune time to point out not only how far away this is, but how long ago this happened.

Time? Lightyears. As in this happened 30 million years ago and we're just hearing about it now. Want to know what happened on Earth 30 million years ago? The landmass of India ran in to Asia. Earliest sightings of Sperm Whales were found about here. A giant snake later named Yurlunggur lived, believed to be the genetic tie between snakes and lizards. Yep. That's what Earth was up to and we know everything after that up to the present. What's happened to this black hole since 30 million years ago though? No idea.

Distance? Well, if you were able to wrap a huge telescope once around the Earth to look at the back of your head (pretend for a second that this would work), it would take light approximately 129 milliseconds to bounce off the back of your head, go through the telescope, and be picked up by your eyes. A little over 1/10th of a second to go all the way around Earth. Give it a full second and it'll wrap around Earth a little more than 7 times. Something that goes that fast took 30 million years to get here.

..and all that is over 30 times closer to us than the supermassive black hole that was mentioned first.

^ That's true. And the funny thing is .. in astronomy 30 million [light] years is "not that much". Young Universe needed ~ 550 million years to form first stars.
 
Beautiful avatar.

Massive black hole indeed

Maybe one day it will be possible to visit the Black Holes :-)

While we are talking about black holes, I saw a discussion about 'holographic universe' which basically suggests that all matter surrounding the black hole (essentially the whole galaxy around the central black whole) is encoded as an information on the event horizon of a black hole - or the state of the matter is linked to changes in the black hole horizon almost as the matter is a holographic projection of the black hole.
It does sound silly, but it is fun* to watch:

* very broad definition of fun

tucking that one away for later :toast:. ta.
 
Apparently there are black holes discovered recently which existence and growth rate can't be explained with currently accepted scientific model.
So far 40 quasars were discovered that have super massive black hole in their center, with 39 of them black holes are around 1 billion times mass of the sun (center of our galaxy is only 4 to 5 million times mass of the sun) ... and one quasar among them has a black hole with mass 12 billion times the mass of the sun.
They originated when universe was young (only 900 million years old).

Black holes cause BLASTS in the cores of galaxies: Supermassive objects lead to thousands of stars forming every year.


giphy.gif



Many galaxies blast outward from their centers huge, wide-angled flows of material — pushing to their outer edges enough dust and gas each year to otherwise have formed more than a thousand stars the size of our sun. Astronomers have sought the driving force behind these massive molecular outflows, and now a team led by University of Maryland scientists has found an answer.

a short interesting read

If you want to create a black hole. Then if under 10 trillion Tonnes of mass needs to be squeezed into a 25 mm by 25 mm by 25 mm ball. Also if it's 25 meters ball then u need much more starting mass.
I believe that our sun will be 25 cm ball if it goes to that

It's said that the space time layers are connected like webs, 1 and 2 and -1 and -2 in space time layers usually are black and white holes. Black holes can only suck in negative particles and matter can be made out of both positive and negative particles. So often there's a ring around black holes made out of positive particles.

stable time layers that I know of is 7 8 17 18 32 48 82 87 88 97 98 there's probably millions even between these As something can be stable in the decimals. The tip of the key might not be stable but the rest might

White holes are supposed to suck only positive particles and not negative. Some scientist joked that the white version could be out of morphed suns as they might be stuck instead of dragged in. just because the layer is much more stable time wise. Less glitches.

Generally when energy go to super proposions it starts to glitch and leak energy since it's not perfect and physics starts to be altered. The way with fusion reactors is that they gain more energy than put into it. Due to energy leaks from something close time wise that is glitching allready

My favorite topic is energy in quantum physics.

This is my opinion based of knowledge accumulated over my lifespan

Entangled by gravity and destined to merge the candidate black hole duo (called PG 1302-102) in a distant galaxy (located 3.5 billion light-years away) appears to be locked in an intricate dance. The black holes are the tightest orbiting pair detected so far, with a separation not much bigger than the diameter of our solar system. They are expected to collide and merge in less than a million years, triggering a titanic blast with the power of 100 million supernovae.

The smaller of the two black holes gives off more light. While the black holes themselves don't emit light, they accumulate and heat up surrounding gas, which then radiates light. The reason the smaller black hole gives off more light is that it is orbiting farther from the center of mass and closer to the surrounding gas disk, allowing it to gather up most of the gas as it orbits. The result is that the more massive central black hole is starved of gas and doesn't glow as brightly.

The brighter black hole is traveling at nearly 7% the speed of light. (though it takes the black hole 5 years to orbit its companion). At speeds as high as this, which are known as relativistic, the light becomes boosted and brighter.
 
What gives them the impression two black holes colliding causes an explosion? You'd think it would be no different than two stars colliding.
 
That would assume a direct collision; they're in each other's gravity well, spinning around each other. I picture it more like two marbles slowly approaching each other until they uneventfully make contact and become indistinguishable--effectively one mass. If it were head-on collision, it would be very energetic but two massive objects locked in the gravity each other can't have a head-on collision unless it is with a third body moving at high velocity.

FYI, the same thing is predicted to happen with the Milky Way and Amdromedia in 4 billion years (Sol will be dying by then). It is a "relatively common" event, yet, the skies aren't full with blindingly bright explosions; hence, why I'm a skeptic. Here's an interesting PDF about it and their respective galactic cores (again, generally uneventful):
http://acme.highpoint.edu/~afuller/PHY-1050/resources/GreatMilkyWayAndromedaCollision.pdf
Large galaxies also contain supermassive black holes in their centers. During a merger, the two black holes sink to the center of the newly formed elliptical, creating a tight binary that loses orbital energy as the pair gravitationally flings passing stars into higher orbits. When the black holes come within a light-year of each other they are destined to merge through the emission of gravitational waves (August issue, page 16). Gas dumped onto the new monster black hole can form an accretion disk that shines as an incredibly luminous quasar or a more modest active nucleus (July issue, page 40). All of these amazing phenomena will occur when the Milky Way and Andromeda merge, and the Sun will have to ride it out.

No "blast."


Also:

"Is?" It happened 3.5 billion years ago. Yeah, I'm nitpicking but seriously, that puts things into context. We're seeing an event that occurred as Sol was forming. It is ancient.

If a binary black hole forms with initial separation that is not too large then they would inspiral due to the emission of gravitational radiation and eventually merge emitting a fantastically large amount of radiation.

For instance, the radiation emitted during the final second before the two black holes merge could be 5% of the total mass of the system. This makes black hole binaries emit in gravitational waves more energy than a star of comparable mass emits in optical radiation throughout its billions of years of life-time.

The merger will result in a highly deformed single black hole which rids itself of its deformity by emitting gravitational radiation that is characteristic of the mass and spin of the final black hole. This is called the quasi-normal mode or the ring down signal.
