Doesn't it make *you* a little suspicious? After all,
the hunt for the graviton has been a major goal of
theoretical physics for a long time now, and there's
nothing on the immediate horizon to give much hope
that it will soon be discovered.

To expound further - Some good reading

I draw your attention to para. 2 that starts

"Gravitons are postulated because of the great success of the quantum
field theory...."

Painius admits he cannot answer a single question to NB:

"Yes, you're right of course, NB. And they get very useless very quickly.
I shall do my best to ignore them, as you wish."
