Fermi realized that any civilization with a modest amount of rocket technology and an immodest amount of imperial incentive could rapidly colonize the entire Galaxy.

Yeah, whatever. No sane person with even a rudimentary knowledge of physics, much less an expert, could possibly believe something this preposterous.

Actually, contrary to those who think that the speed of light cannot be breached, it can be and has (quite recently in separate lab tests). Fermi's paradox is therefore alive and well.

a rudimentary knowledge of physics

The galaxy is about 100,000 light years across. The speed of light doesn't need to be exceeded to allow for a civilization to spread out and occupy the entire galaxy in 10 million years from GO! Or even 1 million years. Getting to the next galaxy [Andromeda] is a different story.

There are also some interesting theories about gravity being the wave/particle duality and that the speed of gravity is many times that of the speed of light.

Not in any way that's relevant to travelling from point A to point B. No violation of Einstein's relativity has ever been observed. Popular articles about light pulses travelling faster than c stem from a confusion about the difference between group velocity and phase velocity.

"Fermi's paradox is therefore alive and well."

Not really. Such a conclusion requires scores, if not hundreds, of assumptions.

I'd be pretty embarrassed if my international reputation were based on such a sloppy, off-handed comment.
