What happens if a gamma-ray hits a black hole?
Gamma radiation is still in the light spectrum, and thus its speed is in fact not bigger than the speed of light. so as the other answer already said, the black hole would simply absorb the radiation and nothing would happen.
Do gamma-ray bursts come from black holes?
Gamma-ray bursts are the strongest and brightest explosions in the universe, thought to be generated during the formation of black holes. Though they last mere seconds, gamma-ray bursts produce as much energy as the sun will emit during its entire 10-billion-year existence.
How close would a gamma-ray burst have to be?
roughly 6 billion light years
The spectrum of the object revealed a redshift of z = 0.835, placing the burst at a distance of roughly 6 billion light years from Earth. This was the first accurate determination of the distance to a GRB, and together with the discovery of the host galaxy of 970228 proved that GRBs occur in extremely distant galaxies.
Can Earth survive a gamma-ray burst?
A nearby gamma-ray burst, beamed directly at Earth, is pretty unlikely. However, if one did occur, the amount of damage would depend on how close the burst is. With the gamma-rays beamed directly at Earth, the radiation would destroy a significant portion of our atmosphere, specifically the ozone layer.
How often do GRBs happen?
Observations of deep space suggest that gamma ray-bursts are rare. They are thought to happen at the most every 10,000 years per galaxy, and at the least every million years per galaxy.
Could a gamma-ray burst hit Earth?
Could a gamma ray burst hit Earth?
Can a gamma ray escape from a black hole?
According to general relativity, space is warped, or curved, by matter. Although visible light cannot escape from a black hole, high-energy radiation, like gamma rays, can escape. Thousands of black holes have now been identified in our Galaxy.
What causes gamma ray burster?
Long gamma-ray bursts are associated with the deaths of massive stars, while short gamma-ray bursts are most likely caused by the mergers of neutron stars. For the most part, long gamma-ray bursts happen in galaxies very different from the Milky Way — dwarf galaxies low in any element heavier than hydrogen and helium.
What are facts about gamma rays?
Gamma rays are produced from the excited nucleus of a radioactive element. An excited radioactive element decays to form its daughter element by a process called isometric transition. Gamma rays are emitted during an isometric transition from higher energy nuclear state to lower energy state.
How does black hole admit gamma rays?
The scientists say the rotation of the black hole induces an charge separated magnetosphere that creates parallel electrical charges around the poles. These then accelerate particles to very close to the speed of light, causing gamma radiation to be thrown out into space from inside the event horizon.
