The real reason why we have gravity is not only because of space
curvature, but also because of time dilation, the two basic tenets of
Relativity. Space curvature is easy to visualize, but not so much time
dilation. Here they visualize time dilation like fluid flow. You might
be surprised that most of the gravity we feel on Earth is from time
dilation, because we're not in orbit around the Earth.
