What is gravity?
====--> The gravity can be considered to be a quality or property of the matter with which a reciprocal attraction takes place between the bodies. It is one of the most fundamental forces of the nature but also the weakest with regard to other. ====

How does the Einstein’s Relativity Theory relate with gravity?
====--> The theory of Einstein's Relativity holds that the time and the movement they are relative for the observer and they are related to the gravity, which modifies Newton´s Gravity theory. ====

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

====4. The narrator presents some examples in the video. What happens in the first one? What happens to the sun and planets? Explain ==== ====--> The first example that the narrator presents is of creating a cosmic catastrophe. For which, it is necessary to imagine that suddenly and without any warning, the Sun vaporizes and completely disappears. ==== ====--> Two things, an offer happens with the Sun and the planets for newton and the counterreciprocal for einstein. Newton was saying that the planets would fly immediately of his orbits and would float in the space. And besides the fact that due to the fact that the gravit force was acting to the instant, the planets would feel at once the effect of solar destruction. On the other hand, Einstein was saying that Newton was missed. Since it demonstrated that the gravity was travelling more rapid than the light with what the light was not travelling to the instant, therefore the planets could not demolish of his orbits before that the darkness was noticing. ====

5. What happens in the second one? What happens to the sun and planets? Explain
====--> The narrator presents the same example, only that now einstein introduces the hypothesis of which if the Sun eliminates then the gravitational disturbance it would form a wave that would travel about the space-time and a change would be obvious in the orbit when the wave reaches to the Earth. ====

6. Why was Newton’s idea of gravity incorrect for Einstein?
====--> For einstein newton's idea of the gravity was incorrect since newton does not bear in mind the rapidity in which the gravity travels. ====

7. What is the final definition of gravity given in the video?
====--> The last definition given in the video was created for einstein who thought about a fabric space-time about which they were united the time (in a dimension) and a space (in three dimensions). Then, across the relation of the universe with the geometry, he concluded that the objects move along surfaces in the above mentioned fabric, which later receives the gravit name. ====

<span style="color: #c78bf8; font-family: Tahoma,Geneva,sans-serif; font-size: 110%;">9. What’s the difference between Newton’s gravity and Einstein’s gravity?
--> The difference between both gravities is that that of Newton does not bear in mind that the speed of the light is more rapid than any other thing that travels in the Universe which if it is taken in account in the gravity of Einstein.
