According to Einstein, is gravity a force?
Does gravity always behave like a force?
Is gravity really a force?
If so, why isn't there any "antigravity" in the Universe?
According to Einstein's' theory, gravity is not a force.
Every form of energy/mass is a source of gravitational field which appears as
the curvature of space-time. Particles move in straight lines in these curved
space-times. These straight lines of curved space-time need not be straight in
flat space we're used to and think in. For example, Earth's orbit around sun is a 'straight line' !!
