  Friends, you are watching a legend of humankind. Just think, here is a man that at 90 years of age, while most of his peers are retired enjoying themselves, has traveled to Singapore to bless people with knowledge.

  Thank you, &nbsp; &nbsp; &nbsp;<br>World Scientific Publishing &nbsp;for sharing this video. Dyson is a brilliant theoretical physicist. It&apos;s somewhat sad to see him at ninety struggling with simple phrases. On the other hand, it&apos;s great to see him talking about a subject that people sixty years his junior would struggle with. All the knowledge is in Dyson&apos;s head, it&apos;s simply that as he has aged it has become harder to articulate his thoughts. He will be aware of this himself.<br>For those who follow Einstein, gravitation can be explained as space-time curvature due to matter. Matter tells space-time how to curve! If gravitons should be detected, surely this would not bode well for General Relativity. Such force carrying particles (if we equate them to photons in classical EM theory) would obviate the necessity for a curved space-time due to matter. I find it inconceivable that the presence alone of gravitons would so neatly &quot;fit the bill&quot; as Einstein&apos;s field equations do in describing curvature of space-time.<br>Thanks once again for affording me the pleasure of seeing and listening to this brilliant man.

  So, hypothetically you would need a Dyson sphere to detect even one Graviton...

  <a href="https://www.youtube.com/watch?v=l-FSFtoeagc&amp;t=862">14:22</a><br>Just to note that in the 2nd volume of Fuller’s ‘Synergetics’ (published 1982 MacMillan-Collier) there exists a passage where he describes the process how a ‘spent’ radiant particle ‘turns’ and becomes integral with that ‘unit’ which is gravity. (Not myself in a position to comment.)

  Gravity seems to remove less distance at the square of the distance from the gravitation.
