The first direct observation of gravitational waves was announced by the Laser Interferometer Gravitational Wave Observatory (LIGO), which is a great advance in science. Previously, gravitational waves were only inferred indirectly, through their effect on the timing of pulsars in the binary star system and the waveforms consistent with Einstein’s predictions of general relativity. But American theoretical physicist Dr. James Gates says there is another theory about German genuis that could soon be proved correct.
Speaking in Neil deGrasse Tyson’s StarTalk podcast, he said: “In 1905, Einstein wrote four articles, and one out of them showed that energy must be quantified.
“We know that Einstein didn̵7;t like quantum theory, but he was actually one of the founders of this paper on the photoelectric effect.
“Now that we’ve seen gravitational waves, we want to see the quantization of the energy carried by those waves.
“When we do that, we’ll have gravitons in our universe.
“You want to be able to see the quantization of the energy that gravity waves hold to tell you that the graviton – at that point it is no longer science fiction – is part of science.”
In theoretical physics, the graviton is the hypothetical quantum of gravity, an elementary particle that mediates gravity.
Dr. Tyson broke it down into a simpler explanation.
He added: “A photon is a particle of light, but you could also say light is a wave, so that’s a suitable analogy.
“We measured gravitational waves, now we want to measure its particles.”

But Dr. White said the graviton discovery could disrupt that.
He continued: “Discovering a gravity will require a real rethinking of what gravity is.
“Some of us were there, I don’t think geometrical gravity, it’s sensory theory.”
To confirm, Dr. Tyson asked: “What you are saying is that Einstein’s theory happens to be a convenience in certain situations giving you the correct answer?
“Are you fine with that, but isn’t it the whole story?”
Dr. White confirms the claim to be correct, explaining that more work needs to be done to better understand what gravity is.
