1. What is gravity?
It is the force that attracts bodies in proportion to their mass.

Isaac Newton
==== 3. How does the Einstein’s Relativ ity Theory relate with gravity? ==== The Relativity Theory say that the space-time couldnt be plane in the presence of matter and that the curvature of  space-time would be perceived as a gravitational field.

==== 4. Mentio n five words you might find in the video ====

// ***During watching and after watching** //
1. Which of the words in the question above did you find in the video? List them

5. Why was Newton’s idea of gravity incorrect for Einstein?
Because Newton believes that gravity was a force that works at any distance, this mean that when the sun actually disappears it would directly affect us, however Einstein didn´t believe on that and he knew that the light doesn´t travel  instantaneously and that it takes it some minutes to travel so if nothing could travel so fast how the planets could move  out of its orbits before the darkness reach our eyes.

Einstein called this General Relativity.

<span style="color: #808080; font-family: Tahoma,Geneva,sans-serif; font-size: 15px; line-height: 22px;">That Einstein took into account the speed of light and the four dimensional space-time that makes him understood that <span style="color: #808080; font-family: Tahoma,Geneva,sans-serif; font-size: 15px; line-height: 22px;"> gravity was about warps and curve that travels at the speed of light, while Newton believe that gravity was an <span style="color: #808080; font-family: Tahoma,Geneva,sans-serif; font-size: 15px; line-height: 22px;"> instantaneously force.
