==== **Before watching ** ==== ====What is gravity? ====

Who discovered it?
====Gravity was discovered first by Sir Isaac Newton. ==== ==== How does the Einstein’s Relativity Theory relate with gravity? ====

====I really don't know because I don't understand his Relativity Theory well. ==== ====Mention five words you might find in the video ====

====Gravity, force, attraction, size, orbit ====

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

====<span style="color: #000000; font-family: arial,helvetica,sans-serif; font-size: 1.066em; font-weight: normal; line-height: 19px; margin-bottom: 0px; margin-left: 0px; margin-right: 0px; margin-top: 0px; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 5px;">Newton didn't actually know how does Gravity work. ====

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

In the first example, the sun explotes and instantaneously the planets get out of orbit.
====<span style="color: #000000; font-family: arial,helvetica,sans-serif; font-size: 15px; font-weight: normal; margin-bottom: 0px; margin-left: 0px; margin-right: 0px; margin-top: 0px; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 5px;"><span style="color: #c78bf8; font-family: Tahoma,Geneva,sans-serif; font-size: 15px; line-height: 22px;">5. What happens in the second one? What happens to the sun and planets? Explain ====

In the second one, the sun explotes and in 8 minutes (time that light needs to arrive pur planet) the force or wave makes the Earth get out of orbit.
==== <span style="color: #c78bf8; font-family: Tahoma,Geneva,sans-serif; font-size: 15px; line-height: 22px;">6. Why was Newton’s idea of gravity incorrect for Einstein? ====

Because he thought the Force of Gravity was instantanious, meaning that it is faster than speed of light.
==== <span style="color: #c78bf8; font-family: Tahoma,Geneva,sans-serif; font-size: 15px; line-height: 22px;">7. What is the final definition of gravity given in the video? ====

It has something to do with time and space, and how they make warps and curves in it.
==== <span style="color: #c78bf8; font-family: Tahoma,Geneva,sans-serif; font-size: 15px; line-height: 22px;">8. What’s the name Einstein gave to it? ====

====<span style="font-size: 1.066em; font-weight: normal; margin-bottom: 0px; margin-left: 0px; margin-right: 0px; margin-top: 0px; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 5px;">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? ====

====<span style="font-weight: normal; margin-bottom: 0px; margin-left: 0px; margin-right: 0px; margin-top: 0px; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 5px;">That in Einstein's, the force of gravity has to do with time and space. ====
