New Theory of Gravity Decouples Space & Time

eldavojohn writes "Petr Horava, a physicist at the University of California in Berkeley, has a new theory about gravity and spacetime. At high energies, it actually snips any ties between space and time, yet at low energies devolves to equivalence with the theory of General Relativity, which binds them together. The theory is gaining popularity with physicists because it fits some observations better than Einstein's or Newton's solutions. It better predicts the movement of the planets (in an idealized case) and has a potential to create the illusion of dark matter. Another physicist calculated that under Horava Gravity, our universe would experience not a Big Bang but a Big Bounce — and the new theory reproduces the ripples from such an event in a way that matches measurements of the cosmic microwave background."

    Communicating faster than the speed of light? Isn't that straight out of Science Fiction? The Ansible in Ender's Game/Speaker for the Dead/Xenocide fame... Sweeeet... can't wait to meet a bugger.

    Thank You!

    i was actually thinking of saying something similar but chose not to, so as to avoid another debate about God. it always baffles me how stiff-necked the scientific community can be at times. the only times when things progress is when they can get over themselves and say, "hey maybe theres something we dont know here"

    Saying there are lots of varieties is a dodge NOT a defense. If you want to give specific religious belief systems I will take my time to kill them one at a time. Just because adherents don't all make the SAME mistakes doesn't mean they aren't making them.

    Anywho, God-of-the-gaps is possibly worse than fundies... Rather than having a rather silly axiom that you chose. You end up with shit tons of rationalization. At least fundies are compatible with science or rather the scientific method of discovery (for things outside the purvue of the bible).

    Gaps people have to rationalize millions of divides between essentially two disparate belief systems that constantly contradict one another. It isn't good at all, it comes from cowardice, or some other crappy emotion.

    At least I can respect fundies for throwing down with a side, it takes balls to say in public that you believe half the crazy shit in the bible.

    All faith is blind.

    Your girlfriend ditched you, huh?

    Faith is trusting people. Or not.

    People communicate - that is one of the three ways we know things (the other two are reason and our direct experience).

    We know lots of things by communication ... because we trust the people who communicated it. How many people take the time to verify for themselves everything they read in science books? I have never been to Moscow, but I know it exists - and I have never seen a proof from pure reason that a Moscow must exist, so that rules out both experience and reason. I know Moscow exists by communication from people who have been there - and I trust them.

    The human race is built on shared experience - which means trust.
