Is there really such a thing as a force of gravity especially as it can’t be explained in quantum mechanics?

If a singularity is formed by a very dense mass and causes time and space to bend, then instead of trying to explain gravity perhaps what appears to be a gravitational force is in fact space bending causing a spiralling effect towards any mass? So is there really such a thing as a force of gravity especially as it can’t be explained in quantum mechanics?

  1. Yes, there is a force of gravity since we can measure it, and see many indirect consequences of gravity (bending of light, gravitational lenses, …). Physics is an experimental science, and we have to be able to test our laws by measurement!
    No, we don’t fully understand it at the smallest length scales (the Plack length), and at the highest strengths (near a black hole, especially if it rotates).
    This is a common occurence in physics, where we see slightly different physical laws at different scales. For example, we are happy to use Newtonian mechanics to describe our world, but if we look at atomic scales, we have to use quantum mechanics.

  2. Yes, there is a force of gravity or we’d be floating in mid air, even in space. I learnt about this in t3 in science at hs and there is a gravitational force. I didn’t really listen so much but I hope this helps. Although the reply above is more, sorry, much more better than this one, but I just like finding sites where I can put replies and answers to things on that I’m interested, or know about.
