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' !!
