Why can’t we create our own gravity, like lab created gravity. Isn’t gravity just a big object pushing down on some sort of “plane” ?
In: Physics
Gravity comes from huge mass, which the earth has. It “pulls” things to it. Your body also has mass but it’s much less than the earth so the earth wins and pulls you down to it. That’s why we weigh much less on the moon, the moon has much less mass than the earth, so it doesn’t affect our own body’s mass and pull it towards the moon as much.
It’s much more complex than that (Google curved space for a fun night!) but to your question, in order to do that we would have to generate a ton of mass first.
Where are you thinking we would want to create gravity?
Edit: after reading your question again, “lab created” gravity, I assume you mean create it here on earth. As you may guess now, in order to do that you’d have to generate more mass, or atleast enough to compete with the earth’s already super strong mass to have any meaningful effect.
You can do it in other ways, like static electricity (rubbing a balloon on your head makes your hair stand up towards the balloon), magnetism/electromagnetism (thinking of that scene in Lost where they stop pushing the button), inertia(like on the Gravitron ride at the fair).. There’s lots of different kinds of forces besides gravity that can “invisibly” affect other objects.
