# What are the theories of Albert Einstein?

## What are the theories of Albert Einstein?

Einstein is also known for his theory of general relativity (an explanation of gravity), and the photoelectric effect (which explains the behavior of electrons under certain circumstances); his work on the latter earned him a Nobel Prize in Physics in 1921.

### What exactly is the theory of relativity?

What is general relativity? Essentially, it’s a theory of gravity. The basic idea is that instead of being an invisible force that attracts objects to one another, gravity is a curving or warping of space. The more massive an object, the more it warps the space around it.

What was Einstein’s theory of life?

So on a piece of hotel stationery, Einstein wrote in German his theory of happiness: “A calm and modest life brings more happiness than the pursuit of success combined with constant restlessness.”

What is Einstein gravitational theory?

Einstein did. He theorized that a mass can prod space plenty. It can warp it, bend it, push it, or pull it. Gravity was just a natural outcome of a mass’s existence in space (Einstein had, with his 1905 Special Theory of Relativity, added time as a fourth dimension to space, calling the result space-time.

## What are the two theories of relativity?

The theory of relativity usually encompasses two interrelated theories by Albert Einstein: special relativity and general relativity, proposed and published in 1905 and 1915, respectively. Special relativity applies to all physical phenomena in the absence of gravity.

### What are the 8 ways you can see Einstein’s theory of relativity in real life?

8 ways you can see Einstein’s theory of relativity in real life

• Profound implications. (Image credit: Keystone/Hulton Archive/Getty)
• Electromagnets.
• Global Positioning System.
• Gold’s yellow color.
• Gold doesn’t corrode easily.
• Mercury is a liquid.
• Light.

How is e mc2 used in everyday life?

When you drive your car, E = mc2 is at work. As the engine burns gasoline to produce energy in the form of motion, it does so by converting some of the gasoline’s mass into energy, in accord with Einstein’s formula. When you use your MP3 player, E = mc2 is at work.

What did Albert Einstein think of parallel universes?

Einstein didn’t think about parallel universes at all. The idea of parallel universes is and was being investigated by scientists using Einstein’s theory of relativity, not by Einstein himself.

## Are there any problems with the parallel universe theory?

Not everyone agrees with the parallel universe theory, however. A 2015 article on Medium by astrophysicist Ethan Siegal agreed that space-time could go on forever in theory, but said that there are some limitations with that idea. The key problem is the universe is just under 14 billion years old.

### Why did Brian Greene study parallel universes?

Greene explains that when he began studying string theory and parallel universes, it wasn’t because he could one day measure energy at CERN or develop new mathematical equations. He simply liked the idea, he says, of studying something on such a large scale.

How are the Parallel Universes separated from US?

In some, the parallel universes are separated from us by enormous stretches of space or time; in others, they’re hovering millimeters away; in others still, the very notion of their location proves parochial, devoid of meaning. A similar range of possibility is manifest in the laws governing the parallel universes.
