RE: The Theory of Everything: Introduction to String Theory (FOR BEGINNERS!) - Part 2/2

Thank you @agcrypt for your query. I agree with your comment to some extent; but you must realise that it is not just the spinning that causes a centripetal force (the force acting towards the centre = gravity), but mass also plays a huge part. For a light object to have the same gravity as a much heavier object, it must be spinning much quicker. The Earth is huge and extremely heavy. Hopefully this helps you out in some way or another!

Yeah, I get what you are saying. This is the stuff we've been spoon fed our entire lives. Since gravity is only a theory and there is zero proof that it actually exists, I just think that it should be re-examined.
