blackholes energy?

Question

What happens to all the energy that is absorbed within a blackhole?
If it is converted all to light, where is all that energy being transfered to. Shouldnt space be heated up or something

Answer 1

The gravity of a black hole is so strong that light cannot escape it.

The energy that is released black holes is mostly in the form of x-rays.

Answer 2

AND THE CORRECT ANSWER IS..........

Blackholes aren't as black as you were lead to believe. They have a temperature. It's very small and the larger the mass of the blackhole the smaller the temperature gets. (We're talking 10 ^-6 deg Kelvin above absolute zero).

Spontaneous particle creation in vaccuum described by the uncertainty principle (quantum effect) results in some particles falling into the BH while the equal and opposite particle escapes. Its these escaping particles that give rise to the gentle outflow of energy - its called Hawking radiation. Given enough time (10 ^88 years) a black hole will evaporate.

Now, if the black hole is rotating then there is another mechanism for energy loss and this is the creation of gravity waves - they're still trying to detect these. Essentially the BH is so humongous that it is able to drag space and time around it as it rotates (its called frame dragging, its a bit like stirring a cup of tea) and waves in space and time are produced that issue out away from the BH - this reduces the BH rotational energy over time.

One final point - for tiny tidgy little BH's (towards the end of the black holes life due to Hawking radiation evaporation), when the event horizon is down to the diameter of an atom, the Hawking radiation is so large that the temperature of the BH increases such that visible radiation is produced - so black holes can shine.

If we could create such an object it would be an incredible power source.

Answer 3

AND the acceptable answer IS.......... Blackholes are not to any extent further as black as you've been convey forth trust. they have a temperature. it really is thoroughly small and the more suitable helpful the mass of the blackhole the smaller the temperature receives. (we are speaking 10 ^-6 deg Kelvin above absolute 0). Spontaneous particle introduction in vaccuum defined by the uncertainty idea (quantum result) leads to some debris falling into the BH at the same time as the equivalent and opposite particle escapes. Its those escaping debris that grant upward push to the comfortable outflow of means - its said as Hawking radiation. Given sufficient time (10 ^88 years) a black hollow will evaporate. Now, if the black hollow is rotating then there is yet another mechanism for means loss and that is the introduction of gravity waves - they're although attempting to locate those. absolutely the BH is so humongous that it really is able to tug section and time round it because it rotates (its said as body dragging, its in effortless words like stirring a cup of tea) and waves in section and time are produced that project out a recommendations off from the BH - this reduces the BH rotational means by using the years. One very very last element - for tiny tidgy little BH's (in the route of the top of the black holes life through Hawking radiation evaporation), at the same time as the type horizon is all the way down to the diameter of an atom, the Hawking radiation is so tremendous that the temperature of the BH will advance such that considered radiation is produced - so black holes can shine. If shall we create such an merchandise it ought to nicely be an excellent means source. best needs LT

Answer 4

OK here we go....

Hawking is the Lucasian Professor of Mathematics at the University of Cambridge, and a Fellow of Gonville and Caius College, Cambridge. He is known for his contributions to the fields of cosmology and quantum gravity, especially in the context of black holes, and his popular works in which he discusses his own theories and cosmology in general. These include the runaway popular science bestseller A Brief History of Time, which stayed on the London Sunday Times bestseller list for a record-breaking 37 weeks.[1]

His two most important scientific contributions up until now have been providing, with Roger Penrose, theorems regarding singularities in the framework of general relativity, and the theoretical discovery that black holes emit radiation, which is today known as Hawking radiation (or sometimes as Bekenstein-Hawking radiation) [2].


From wikipedia, i suggest u get his book, im going to :D
im only 14, but...I GOT THE BEST ANSWER!!!!

Answer 5

I just studyed this tuesday in topics in physcial Science the answer is the mass that is absorbed by a black hole is converted in to energy. A black hole is a star that is I beleve 80+ times the mass of our sun that has gone supernova (exploded and died) but it is dark matter (no light) and has such a strong gravitional pull that nothing can excape it not even light. A black Hole has been found in the middle of our Glaxy and it is beleved that we are slowly being pulled towrd it. Don't wory it wouldn't happen for several thousand years

Answer 6

My limited understanding is that a blackhole is an extremely dense (beyond comprehension) object whose gravitational pull is so strong that even light within this field cannot escape. When matter is pulled into the blackhole, it combines with the extremely dense object within, adding to its mass. I do not know what happens once this reaches a critical mass, if any.

Answer 7

It's all theory. How can anyone know the answer. If black-holes do exist then it's probably the death and life cycle of each galaxy, just like all things in life....... every thing has a centre......... a beginning and an end. I would assume there is a black-hole at the centre of most galaxies.
The gravity is probably so immense that mankind would not be able to travel beyond our galaxy, especially if light waves can't escape it pull.

Answer 8

This is still a controversial subject in physics. The energy would be captured within the black hole, but might eventually be readmitted in the form of hawking radiation (that's the controversial part)

Incidentally general relativity states that, just like mass, if enough energy is concentrated in one place, it too can trigger an event horizon and generate its own black hole. Such a hole is known as a kugelblitz.

Answer 9

The black hole captures both energy and matter. It's being crushed, or better to say, packed into an infinitesimally small poin in space with an infintite density. I can prove that easily.

If Density equals mass divided by volume, then we substitute the black hole's supposed measurements:

D= (infinite mass) divided by (0 volume)
so....
D must equal infinity or undefined because we have infinity over 0. The undefined part gives me an uneasy feeling though...

Answer 10

A black hole to my understanding, is extreme gravity, where even light can`t escape.
