We are also featuring Einstein on our blog and have posted intruging photos of his life and death. Take a look. http://www.americanbiotechnologist.com/blog/einstein-photos/ Great article.

If so, the so-called "red shift" could be explained as the Doppler effect of slower light rather than expanding galaxies.

What drives the expansion of space/time? Could it be the very wierdness of quantum mechanics in a vacuum? As I understand it, particles continuously "pop" into existence and then disappear. What if when they appear, they actually create the tiny space they occupy, pushing space/time apart to make room. When they then disappear, they leave that empty space behind, adding to existing space/time. Are there enough of these "poppers" to account for observed expansion? Could this be tested somehow? How much would such particles weigh? Could an aggregate weight estimate begin to explain "dark matter?" Dark energy? Unfortunately I am not educated enough in the field to pursue this further, or enough to know if this even makes sense. I await responses from better educated folks to either tell me I'm all wet or on to something. Just a thought here. What drives the expansion of space/time?

If they have proved that gravity is affecting everything at the rate it should based on mass and that distance has no effect on gravity, its a very serious problem for the multiverse theory i guess. Unless our universe is the first. i not sure i understand what they have achieved.

That is because expansion of the Universe cannot happen w/o an energy source to drive it continuously, and that is because expansion requires constant creation of new volume of space-time and unit volume of space-time must have a constant unit amount of zero-point energy. So w/o a continuous energy source the expansion cannot really continue. I think even if the gravity was really weaker at large distances it still would not be enough to get rid of Dark Energy.
