Comment on we are but a gravy train in outer space

Wisdom is still not putting it in a fruit salad.
Gravity isn’t a force. Its effects can be mapped to an equivalent pseudo force and used as such. Outside of general relativity, or Quantum mechanics discussions, gravity is a force.

But is it fundamental though?

We don’t know. Right now, relativity and QM fundamentally disagree on what gravity is. Both are also hugely accurate in their predictions. QM treats it as a force comparable to EM or the strong force. GR says it’s space itself moving. The force we experience is just a reaction to us trying to stay still, as space moves through us.
Beyond that, defining anything as fundamental is a challenge. How are you using fundamental?
