Quantum Gravity How quantum mechanics ruins Einstein’s general relativity

Einstein Field equations explained intuitively and visually: Isaac Newton changed our paradigm by connecting earthly gravity, with the movement of heavenly bodies. He formulated an equation that is still used today – the law of universal gravitation. But it had problems – action at a distance and the the rate of precession of Mercury

250 years later, Einstein, with the General theory of relativity, solved the riddle of Mercury’s precession, and showed that gravity was due to a bending of space-time itself. Today, we find holes in Einstein’s theory, such as its inability to explain the singularity inside black holes, and the big bang.

Newton’s and Einstein’s equation are similar . They both have Newton’s gravitational constant. In Newton’s equation, a force is on the left side, created by mass on the right side. In Einstein’s equation, the analog of force, the curvature of space-time is on the left side. And mass-energy-momentum tensor is on the right side.
