### 70 Years of Pursuing Quantum Gravity: A Look at the Progress and Pioneers

- Quantum gravity is a field of theoretical physics that has not yielded any tangible results in 70 years
- Quantum gravity replaced unified field theory, which was a pursuit of Einstein’s
- Edward Whitton proposed string theory in 1984 as an anomaly cancellation, and he is largely revered by the physics community
- Between 1953 and 1973 real physics progress was made
- Quantum gravity does not appear to have yielded any physical results in 70 years despite the best minds attempting it, and the resources dedicated to it
- Michio Kaku, Sean Carroll, Herman Bondi, Brian Greene and others are involved with string theory.

### Exploring the Unanswered Questions of Einsteins Theory of Space-Time

- Einstein’s theories are accepted as an effective model that fundamentally describes how space-time works
- However, mathematicians and physicists have yet to account for singularities within this model
- These singularities indicate that there is a mistake in their equations, causing a division by zero error
- New theories such as non-commutative geometry try to avoid the fact that the equations may not be accurate
- This is similar to avoiding doing homework for 50 years, expecting someone else to take over and make it right.
