Hi there.(adsbygoogle = window.adsbygoogle || []).push({});

This is my first posting to this forum, and in fact to any forum in many years, so please excuse me if I have not followed the rules correctly or chosen the correct forum.

I have been watching a lot of Neil DeGrasse Tyson-related videos and it has lead me to a line of thinking that I am wondering about. Perhaps someone here would be kind enough to help me.

So, if gravity is just the curvature of space-time, then is it possible that it is not a "real" fundamental thing? If it is just curvature, then why do we need to unify gravity with the other forces at a quantum level? Would it not make more sense to try and find a quantum description of space-time distortions (liek curvature due to mass) or a quantum description of space-time itself?

I mean, could the effects of gravity, just be a property of matter itself, rather than an external force that acts on matter? How do we know gravity is a fundamental force that need unifying? It is, after all, quite different from the other forces that have already been unified.

My assumption is that since physicists do not seem to be pursuing this line of thinking (that I know of), that I am missing some key concept(s) that invalidates my line of thinking. But, I wonder if someone here might help me to understand what I am missing. Or, if this is a possibility, then what is the current state of this line of thinking and who is working on it?

I will close by saying that my background is computer science, so I have some physics and calculus, but I have forgotten most of it. So, a layman's level explanation would be much appreciated.

Thanks very much.

Krys
