## What is gravity Einstein vs Newton?

Albert Einstein called gravity a distortion in the shape of space-time.

…

Newton’s theory says this can occur because of gravity, a force attracting those objects to one another or to a single, third object.

Einstein also says this occurs due to gravity — but in his theory, gravity is not a force..

## Is gravity a real force?

In general relativity, gravity is a fictitious force. In classical mechanics, fictitious forces are not considered “real” forces. … The issue of gravity being a force or not has nothing to do with general relativity. If you believe that inertial forces are forces, then gravity is a force.

## What is E mc2 called?

E = mc2. An equation derived by the twentieth-century physicist Albert Einstein, in which E represents units of energy, m represents units of mass, and c2 is the speed of light squared, or multiplied by itself. (See relativity.)

## What is Theory of Relativity in simple words?

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.

## Can we create gravity?

Artificial gravity can be created using a centripetal force. … Thus, the “gravity” force felt by an object the centrifugal force perceived in the rotating frame of reference as pointing “downwards” towards the hull.

## What is E mc2 mean?

E = mc2. It’s the world’s most famous equation, but what does it really mean? “Energy equals mass times the speed of light squared.” On the most basic level, the equation says that energy and mass (matter) are interchangeable; they are different forms of the same thing.

## How fast is gravity?

The best results, at the present time, tell us that the speed of gravity is between 2.993 × 10^8 and 3.003 × 10^8 meters per second, which is an amazing confirmation of General Relativity and a terrible difficulty for alternative theories of gravity that don’t reduce to General Relativity!

## Can you remove gravity?

Gravity is the idea that “what goes up must come down”. There is no way to “remove” gravity – though we can briefly simulate that on earth by use of a reduced gravity aircraft. The total vacuum of space, is the absence of air pressure. … You can also make water boil, staying at room temperature, by reducing the pressure!

## What did Einstein mean by time is relative?

The world’s most accurate clock has neatly shown how right Albert Einstein was 100 years ago, when he proposed that time is a relative concept and the higher you live above sea level the faster you should age. Einstein’s theory of relativity states that time and space are not as constant as everyday life would suggest.

## Who invented gravity?

Sir Isaac NewtonSir Isaac Newton was an English mathematician and mathematician and physicist who lived from 1642-1727. The legend is that Newton discovered Gravity when he saw a falling apple while thinking about the forces of nature.

## What is the theory of gravity?

A theory of gravitation is a description of the long range forces that electrically neutral bodies exert on one another because of their matter content. … Best known of these is Albert Einstein’s general theory of relativity, which reduces to Newton’s theory in a certain limit.

## What is the IQ of Isaac Newton?

190Isaac Newton is estimated to have an IQ Level of 190. However, when you look at the huge advances he made in both Physics and mathematics, and the typically high IQ of modern theoretical physicists and mathematicians, we can assume that his IQ is quite high.

## What is more powerful than gravity?

Magnetism, the weak nuclear force and the strong nuclear force are all stronger than gravity. Interestingly, the weaker the force, the larger the distance it is effective across.

## Why is there no artificial gravity?

If it falls down, the same as normal matter, then it has positive gravitational mass, and we can’t use it to build a gravitational conductor. But if it falls up in a gravitational field, that changes everything. With a single experimental result, artificial gravity would suddenly become a physical possibility.
