## What did Albert Einstein discover about Earth?

In 1907, two years after the publication of his theory of special relativity, Albert Einstein came to a key realization: special relativity could not be applied to gravity or to an object undergoing acceleration. Imagine someone inside a closed room sitting on Earth. That person can feel Earth’s gravitational field.

### How did Einstein figure out spacetime?

Instead of a pull, Einstein saw gravity as the result of curved space. He said that all objects in the universe sit in a smooth, four-dimensional fabric called space-time. Massive objects such as the sun warp the space-time around them, and so Earth’s orbit is simply the result of our planet following this curvature.

**Why do things fall according to Einstein?**

Einstein’s understanding of gravity, as outlined in his general theory of relativity, predicts that all objects fall at the same rate, regardless of their mass or composition. To date, Einstein’s equations have passed all tests, from careful laboratory studies to observations of planets in our solar system.

**Why did Einstein move the earth around the sun?**

The Earth moves around the Sun, due to the Sun’s gravity. According to Newton’s theory, the Earth should know immediately that the Sun had disappeared. But Einstein said that couldn’t be right. Because, according to him, nothing can travel faster than the speed of light — not even the effects of gravity.

## What were Einstein’s last words?

Albert Einstein’s last words will never be known. He spoke them in German, but the attending nurse didn’t speak German and so couldn’t recall what was said. He died in his sleep at a hospital in Princeton, New Jersey on April 18, 1955, leaving the Generalized Theory of Gravitation unsolved.

### What did Einstein say about anti gravity?

Newton’s math did a good job at predicting how everything from projectiles to planets moved — but it kept gravity separate from acceleration. Einstein argued that gravity isn’t a force at all. He described it as a curvature of time and space caused by mass and energy.

**What holds the earth and the rest of the universe together?**

Inertia is the force that holds the universe together. Without it, matter would lack the electric forces necessary to form its current arrangement. Inertia is counteracted by the heat and kinetic energy produced by moving particles.

**Why do objects fall on earth?**

Why do things fall down when you throw them or drop them? The answer is gravity: an invisible force that pulls objects toward each other. Earth’s gravity is what keeps you on the ground and what makes things fall. Objects with more mass have more gravity.

## What is space according to Einstein?

Essentially, Einstein thought space and time were intertwined in an infinite “fabric,” like an outstretched blanket. A massive object such as the Sun bends the spacetime blanket with its gravity, such that light no longer travels in a straight line as it passes by the Sun.

### Why is Albert Einstein so famous?

Albert Einstein is one of the most famous scientists in history. His greatest achievement is the general theory of relativity, which describes how the force of gravity works. It is the theory which explains why apples fall from trees, why we are all stuck to the Earth, why the Moon orbits the Earth, and the Earth orbits the Sun.

**How did Einstein contribute to the development of quantum mechanics?**

Einstein is known for developing the theory of relativity, but he also made important contributions to the development of the theory of quantum mechanics. Relativity and quantum mechanics are together the two pillars of modern physics.

**What is Einstein’s theory of space and time?**

Essentially, Einstein thought space and time were intertwined in an infinite “fabric,” like an outstretched blanket. A massive object such as the Sun bends the spacetime blanket with its gravity, such that light no longer travels in a straight line as it passes by the Sun.

## How old was Albert Einstein when he discovered geometry?

The 12-year-old Einstein taught himself algebra and Euclidean geometry over a single summer. Einstein also independently discovered his own original proof of the Pythagorean theorem at age 12.
