We've heard of some crazy dieting fads, but leaving the planet may take the cake. We don't suggest you do that, but we do suggest you answer t...
Don't let this question about gravitational forces get you down! Yeah, yeah...that was an easy joke. You get what you pay for.
THE EARTH'S MASS IS ABOUT TO DOUBLE. Sorry for the extreme tone; we just want to make sure you understand the...gravity of the situation.

to who These air right And here the potential answers

our spacious unaffected help Well one thing we know for
- 00:28
sure the earth has gravity Trust us We've tried to
- 00:31
just jump into space before and when we didn't get
- 00:34
very far That's because the earth has a lot of
- 00:36
mass which creates a lot of gravity and it's not
- 00:39
just the earth Anything that has mass also creates a
- 00:43
gravitational field So we know for sure that option a
- 00:50
is one of the correct answers Because earth has gravity
- 00:54
anything that approaches our planet will feel the pull of
- 00:57
gravity comments asteroids alien warship coming to enslave humanity well
- 01:02
none of them can escape gravity's like the overlord That
- 01:05
also means that we can eliminate option c there's no
- 01:08
way that's correct an option D no way Gravity wouldn't
- 01:11
repel the spaceship so that's wrong as well Now the
- 01:15
spaceship also has masked And remember when we said anything
- 01:18
that has mass also creates a gravitational field right So
- 01:22
if the spaceship has mass it has a gravitational field
- 01:25
that holes on the earth even if it's just a
- 01:29
tiny pole like an ant trying to move bowling ball
- 01:33
The spaceship is in fact exerting of force So our
- 01:37
second correct answer is option b Gravity is a two

up And also remember building a spaceship is the easy 00:01:47.794 --> [endTime] part Buying rocket fuel pontes a lot harder
