Human-made micro black holes However, in some scenarios involving extra dimensions of space, the Planck mass can be as low as the TeV range. It was argued in 2001 that, in these circumstances, black hole production could be an important and observable effect at the LHC or future higher-energy colliders.
Q. What does a white hole look like?
To a spaceship crew watching from afar, a white hole looks exactly like a black hole. It has mass. Physicists describe a white hole as a black hole’s “time reversal,” a video of a black hole played backwards, much as a bouncing ball is the time reversal of a falling ball.

Q. What is a white hole in the universe?
A white hole is a bizarre cosmic object which is intensely bright, and from which matter gushes rather than disappears. In other words, it’s the exact opposite of a black hole. But unlike black holes, there’s no consensus about whether white holes exist, or how they’d be formed.
Q. Has the God particle been found?
In 2012, scientists confirmed the detection of the long-sought Higgs boson, also known by its nickname the “God particle,” at the Large Hadron Collider (LHC), the most powerful particle accelerator on the planet. This particle helps give mass to all elementary particles that have mass, such as electrons and protons.
Q. What can create a black hole?
Stellar black holes are made when the center of a very big star falls in upon itself, or collapses. When this happens, it causes a supernova. A supernova is an exploding star that blasts part of the star into space. Scientists think supermassive black holes were made at the same time as the galaxy they are in.
Q. What type of black hole is the most common?
The most common type of medium-sized black holes is called “stellar.” The mass of a stellar black hole can be up to 20 times greater than the mass of the sun and can fit inside a ball with a diameter of about 10 miles. Dozens of stellar mass black holes may exist within the Milky Way galaxy.
Q. What if the sun was a black hole?
Our Sun is too small a star to end its life as a black hole. But what would happen if the Sun were suddenly replaced with a black hole of the same mass? Contrary to popular belief, the Solar System would not be sucked in: a solar-mass black hole would exert no more gravitational pull than our Sun.
Q. What can escape a black hole?
According to Einstein’s general theory of relativity, the gravity of a black hole is so intense that nothing can escape it.
Q. Do black holes ever end?
A supermassive black hole with a mass of 1011 (100 billion) M ☉ will evaporate in around 2×10100 years. Some monster black holes in the universe are predicted to continue to grow up to perhaps 1014 M ☉ during the collapse of superclusters of galaxies. Even these would evaporate over a timescale of up to 10106 years.
