# Yes, There Is Gravity in Space

28

This week, I settled down to observe the primary episode of The 100. If you have not seen the present, I will simply level out that it takes place within the close to future (although it ran, on the CW, within the close to previous). For causes that I will not get into, there’s a spacecraft with a bunch of youngsters that’s touring from an area station right down to the floor of the Earth. Through the reentry course of, one child desires to indicate that he’s the grasp of house journey and that he is superior. So what does he do? He will get out of his seat and floats round as an indication of his mastery of weightlessness. One other teenager factors out that he is being fairly dumb—and that he will get harm very quickly.

OK, that’s sufficient of the outline of the scene in order that we will discuss physics. The purpose is that there’s one dude “floating” round within the spacecraft throughout reentry.

Earlier than I over-analyze this brief scene, let me add a caveat about my philosophy on science and tales. I’ve talked about this earlier than, so I will simply give a abstract: The primary job for a author of a present is to inform a narrative. If the author distorts science with a purpose to make the plot transfer alongside—so be it. Nevertheless, if the science might be right with out destroying the plot, then clearly I would choose it.

On to the over-analysis!

### What Causes Gravity?

Clearly this scene has to do with gravity, so we should always discuss gravity—proper? In brief, gravity is a elementary interplay between objects with mass. Sure, any two objects which have mass can have a gravitational drive pulling them collectively. The magnitude of this gravitational drive will depend on the space between the objects. The additional aside the objects get, the weaker the gravitational drive. The magnitude of this drive additionally will depend on the plenty of the 2 objects. Higher mass means a higher drive. As an equation, this could be written as:
