Good job Francisco, You have to be careful with capital letters, 3rd person singular "S" in verbs, and contractions. Remember not to use contractions in formal writing

The Elegant Universe Einstein's - Relativity

What is gravity?
IT Is the force that attract two object one to the other

Who discovered it?

IT Was discovered __for__ BY Isaac Newton

==== How does the Einstein’s Relativity Theory relate with gravity? ====

I don't know, but for that I read now, think that the Einstein’s Relativity Theory examines the difference between acceleration and gravity.

==== Mention five words you might find in the video ====

1.- Gravity 2.- Universe 3.- Speed 4.- Relativity 5.- Theory

==== **During watching and after watching **  ==== ==== 1. Click on the following link to watch the video: ==== ==== [] ====

2. Which of the words in the question above did you find in the video? List them

Gravity, Universe, Speed, Theory and Relativity. All the words!

==== 3. What was the embarrassing secret Newton was holding about gravity? ====

He don't know how gravity really works

==== 4. The narrator presents some examples in the video. What happens in the first one? What happens to the sun and planets? Explain ====

He presents a cosmic catastrophe: The sun vaporizes and disappear, the planets immediately fly out of their orbits.

==== 5. What happens in the second one? W hat happens to the sun and planets? Explain ====

Like the first experiment, the sun disappears, but in this case, we are assuming 3 dimensions of space, and a single dimension of time. And this create a curving that make we feel as gravity. When the sun disappears, it will form that travels across the space, and until this wave reach the Earth we would not feel any change

==== 6. Why was Newton’s idea of gravity incorrect for Einstein? ====

For Newton, when the sun disappears we will feel the reaction immediately but Einstein found that the gravity can not travel faster than the light. __This light, take S 8min for the sun's rays travel to the e arth__ wordy

==== 7. What is the final definition of gravity given in the video? ====

It is warps and curves in the fabric of the space and time

==== 8. What’s the name Einstein gave to it? ====

He called that fact as General Relativity
==== <span style="color: #c78bf8; font-family: Tahoma,Geneva,sans-serif; font-size: 15px;">9. What’s the difference between Newton’s gravity and Einstein’s gravity? ====

The difference is that Newton thought the gravity action move S in a infinity speed, however Einstein says that it will travel as the same speed of the light.
