Question: How come their is no gravity in space

Silvia Pardo answered on 16 Nov 2016:

There are two different things here: one is gravity in deep space and the other is gravity while in orbit.
– Deep space is easy: there is no gravity because there aren’t any big objects around that can cause the gravity force. It’s like magnets: one magnet alone won’t do any thing, but when you put it near a piece of metal or another magnet it will cause a magnetic force that will attract one object to the other.
– Gravity while in orbit is also easy but takes a bit of thinking. Astronauts living inside the International Space Station (which is orbiting around the Earth) appear to be floating around, weightless. But gravity is still there, pulling them down to Earth! What’s really happening is that both the astronaut and the space station are both moving at exactly the same rate, so astronauts appear to float from the point of view of the space station. The same thing happens in the drop rides they have on some theme parks, when you ride on one you feel like you float away from your seat but in reality the seat and you are just falling at the same speed.

Phew, that was long, but it’s such an interesting question! Feel free to poke me if something doesn’t make sense 🙂
