I have a limited knowledge of particle physics, yet, I understand that theoretically the range of a graviton is infinite, and the mass of the singularity of a black hole is infinite. I also understand that (theoretically) the effect of gravity is created by the exchange of gravitons and the chance of exchange is greater at smaller distances and greater mass (this is what creates the effect of gravity, am i right?)

So my question is, what stops the singularity of a black hole that is said to have infinite mass, exchanging an equal amount of gravitons with all matter in the universe, thus all matter experiences the same pull as that which is entering the event horizon? Is there a fundamental idea with gravitons, or gauge bosons in general that I am missing, or is my idea on such particle physics completely wrong? Thanks.

Physics tells us that the relative speed of two objects cannot exceed the speed of light, but I just read that the universe is estimated to be 93 billion light years in size. If the universe is 13.7 billion years old, how can the universe have expanded to that size without exceeding the speed of light?

How can humans possibly put a man on the moon in 1969, when technology is STILL so unreliable that we have coputer glitches that screw up simple election votes? (And consider how far we`ve come in 38 years)
Man still hasn`t figured out the simplest of computer glitches, how can they have put together a system to put humans on the moon way back in '69?

Observers, believers and skeptics alike, have been commenting since 2005-6 that reports of UFO sightings and Alien Abductions are down. Indeed, the same old cases many of which occured in the 50's, 60's and 70's get rehashed over and over again. Is the phenomonen changing? Are the Aliens done with their experiments? Is this the quiet before the storm? Was it really just a government conspiracy involving human experimentation and stealth technology? Is the phenomenon even real? What are the causes for the decline in reports?
