ET doesn't need to travel to the stars, ET just needs to send one Von
Neumann probe to one star, and then almost instantly from a cosmic
perspective (less than 50 million years, perhaps much less) the entire
Galaxy would be unrecognizable. And it's not as if this would take some
huge commitment on the part of ET's civilization, in fact even a individual
could easily do it. If Von Neumann probes are possible at all, and I can't
think why they wouldn't be, then they're going to be dirt cheap, you buying
a bag of peanuts would be a greater drag on your financial resources.

I am having difficulty grasping the argument that the reason we can't see
any changes that ET made to the universe with even our biggest telescopes
is because ET can make changes a million times faster than we can.
