# How long can a black hole last?

## How long can a black hole last?

If black holes evaporate under Hawking radiation, a solar mass black hole will evaporate over 1064 years which is vastly longer than the age of the universe. A supermassive black hole with a mass of 1011 (100 billion) M ☉ will evaporate in around 2×10100 years.

What is the meaning of quantum in chemistry?

In chemistry and physics, quantum refers to a single packet of matter or energy. In practical use, it refers to the minimum amount of energy required for a change or the minimum value of any physical property in an interaction. Quantum is the singular form of the word. Quanta is the plural form of the term.

### What is quantum mechanics in simple terms?

Quantum mechanics explains how the universe works at a scale smaller than atoms. It is also called quantum physics or quantum theory. Mechanics is the part of physics that explains how things move and quantum is the Latin word for ‘how much’. Quantum mechanics describes how the particles that make up atoms work.

What’s the opposite of a black hole?

White holes

## Can we see black hole from Earth?

You can ‘see’ the closest known black hole to Earth with the naked eye. There is a black hole in our backyard. Astronomers have found the closest black hole yet at just 1000 light years from Earth, close enough to see the stars that orbit it without a telescope.

What is quantum chemistry used for?

Quantum chemistry strives to accurately predict chemical and physical properties of molecules and materials, which is useful to many fields of science and engineering. Predicting chemical properties using a first principles approach at the atomic scale is a theoretical and computational challenge.

### What exactly is quantum?

In physics, a quantum (plural quanta) is the minimum amount of any physical entity (physical property) involved in an interaction. Quantization of energy and its influence on how energy and matter interact (quantum electrodynamics) is part of the fundamental framework for understanding and describing nature.

Can someone go back in time?

The Short Answer: Although humans can’t hop into a time machine and go back in time, we do know that clocks on airplanes and satellites travel at a different speed than those on Earth. We all travel in time!
