3 Myths in Physics

The three myth of physics that constantly trigger me...

1. Stephen Hawking had once proposed chronology protection conjecture. This great physicist, having made use of Einstein's General Relativity to made postulates for Black Hole Theory, once said: If time travel is possible, where are the travelers from the future? 

So, it is known that Hawking challenged the physics community to somehow prove it both mathematically and experimentally (in an indirect approach) that laws of physics prevent time travel. But the hypothesized wormhole did not prevent time travel by mathematical calculation. 

Chronology Protection Conjecture, history must be protected!!!

2. The detection of gravitational waves. There had been thousands and thousands of experiments that directly and indirectly proved Einstein's General relativity (also known as Einstein theory of gravitation). Yet, in this theory, it predicts the existence of gravitational waves. To date, scientists had calculated the frequency of gravitational wave and it yielded 10^ -30!!! This is way too small too be detected by the built model of gravitational wave detector.

Two physicists, Russell Hulse and Joe Taylor, in 1993, had once successfully detect this extremely small frequency of wave, which gave confidence to physicists to use formula and theory of general relativity without doubt. The problem is, it is only detected ONCE (and they were offered Nobel Prize in Physics)!!! There is still no machines that can fully eliminate ground noise and other disturbance. So, the physics community are still challenged till today to build a gravitational wave detector that functions all the time.

Gravitational Waves is disturbance in spacetime, and a mean of how gravitational force is transmitted.

3. Quantum gravity. This is highly related to Einstein's childhood dream, that is to simplify the beauty of all laws of nature given by God into a single equation, perhaps not even an inch long. But, Einstein had this Theory of Everything listed as his unfinished work that had taken out his last two or three decades, he died with those papers placed messily on his table in 1955. The attempt to unify quantum mechanics and general relativity (theory of gravitational) had always resulted in failure, though tried by geniuses physicists. The significance is, if this is done, then Einstein's dream of creating Theory of Everything (TOE) that unifies all four types of major forces in universe will be finished.

It is now proposed that five versions string theory (or more) are the leading candidates of TOE. Yet, in all its splendor and beauty, it can only describes up to Tenth dimensions (the mathematics broke down at eleventh dimension). Hence, it is profoundly convincing that our world need another genius, on equal footing or surpass the supremacy of intelligence of Mr. Albert Einstein.

String theory proposes that there are more than three dimensions of space, where other dimensions are internal dimensions.
