Can Black Holes Evaporate?
Only Micro Black Holes May Be Able to evaporate but this is not proven.
How do micro black holes evaporate?
It's because: they emit such small amounts of thermal radiation. The radiation is energy, and energy is a form of mass.
Who proposed that black holes can evaporate?
Stephen Hawking was the first scientist to suggest that the black holes evaporate. His theory of Black Holes emitting radiation, also termed as Hawking Radiation.Hawking radiation is black body radiation that is predicted to be emitted by black holes, due to quantum effects near the event horizon. It is named after the physicist Stephen Hawking, who provided a theoretical argument for its existence in 1974, and sometimes also after the physicist Jacob Bekenstein who predicted that black holes should have a finite, non-zero temperature and entropy. Hawking's work followed his visit to Moscow in 1973 where Soviet scientists Yakov Zeldovich and Alexei Starobinsky showed him that according to the quantum mechanical uncertainty principle,rotating black holes should create and emit particles. Hawking radiation reduces the mass and the energy of the black hole and is therefore also known as black hole evaporation. Because of this, black holes that lose more mass than they gain through other means are expected to shrink and ultimately vanish. Micro black holes (MBHs) are predicted to be larger net emitters of radiation than larger black holes and should shrink and dissipate faster.In Hawking Radiation, Virtual particle pairs are constantly being created near the horizon of the black hole, as they are everywhere. Normally, they are created as a particle-antiparticle pair and they quickly annihilate each other. But near the horizon of a black hole, it's possible for one to fall in before the annihilation can happen, in which case the other one escapes as Hawking radiation.
How many different types of black holes are there?
There are four types of black holes. In size and physical construct.Size:Supermassive: These have a mass of between 105 -> 109 million Suns yet have a diameter of 0.001 -> 10 AU (an AU is approximately 150 million kilometers). It is believed that most, if not all galaxies have a supermassive black hole in their centre.Intermediate mass black hole. These have a mass of around 103 million Suns yet have a diameter of 103 kilometers (About the radius of Earth)Stellar-mass. These have a mass of about 10 million Suns but are only around 30 kilometers in diameter.Micro black hole. These have the mass of a million Moons but are tiny, up to 0.1 mm in diameter.Physical construct:Black holes with no electrical charge, and without rotationBlack holes with no electrical charge, and with rotationBlack holes with an electrical charge, and without rotationBlack holes with an electrical charge, and with rotation.See related links for more information
What makes up black holes?
Black Holes are often made during the end of a star,often during a supernova.When they 'die' the star collapses into a single point which is so dense that even light cant escape.Black holes are made up two parts, the singularity and the event horizon. The singularity is the black part, the vacuum. The event horizon is the sphere that covers the singularity, then it acts as a boundary for the black hole.
Can Black Holes Evaporate?

Will LHC kill us all?
No. The micro black holes that it plans on creating will evaporate almost immediately.
Is the lhc going to make a black hole?
One of the LHC's objectives is to create micro black holes. These holes are so small however, they evaporate into radiation almost immediately.
How do micro black holes evaporate?
It's because: they emit such small amounts of thermal radiation. The radiation is energy, and energy is a form of mass.
Where are the micro black holes located?
It isn't known whether micro black holes - usually called primordial black holes - exist at all. If they do exist, they can be at any random location of space.
Are there different types of black holes?
there are four types of black holes. 1. super massive 2. Intermediate mass 3. Stellar mass 4. Micro
What is Stephen Hawking's theory of black holes?
This is far to extensive a subject to be covered here and quite beyond the ability of most people to understand and explain. However Professor Hawking has theorised that even black hole can 'evaporate' by means of Hawking radiation. This will however take a great deal of time. The bigger the hole the longer it will take.
What is a tiny black hole called?
Black holes are generally categorized into three buckets - the largest being called supermassive, the 'medium' being associated with stellar evolution and called 'stellar mass' black holes, and the smallest or tiny ones called "microscopic" black holes.

What has the same mass as a black hole?
A lot of things, actually. The term 'black hole' is applied to an object whose gravitation pull is sufficiently great to prevent light from escaping. Because the magnitude of the gravitational force that one body exerts upon another is, partly, a function of the distance separating the two bodies, black holes can exist at a variety of sizes. There is, for example, a class of black holes known as 'Micro black holes.' These are objects with a radius smaller than 0.1mm (or 100 micrometers, hence the name), with a mass up to that of the Moon. Another class of black holes, called 'Stellar black holes', can have a mass up to that of the Sun, and a radius of up to 30km.
Is there a black hole on the Earth?
It's highly unlikely, as we would have detected it. Micro black holes are physically possible but their existence hasn't been confirmed. One could safely say, that there is no black hole on the Earth and the nearest black hole is a safe, 1,600 light years from us.
