    Can loop quantum gravity see before the Bang?

    Marcus, I appologize for the misspelling of Victor Taveras's name. I thought I had just stumbled across something new and revolutionary, but it had been posted at a while back. This was not mentioned in the book I just read. Do you know any more recent books I can read? Thank you.

    Big Bang Question

    I have heard initial conditions before the big bang described as a singularity, but never a Black hole. I wonder, If there was nothing else in the universe before then, how could we call it a hole? It is interesting to note that the quantum jitters we see at the subatomic level are reflected...

    Can loop quantum gravity see before the Bang?

    The May 20 issue of the journal Physical Review Letters will reveal the results of a National Science Foundation study by Penn State Eberly College of Science grad student, Victo Raveras and Madhavan Varadarajan, a professor at the Raman Research Institute in India that challenge the idea that...

    A laser time machine

    Hello MaxPlank, I have not read the book Time Traveler, but I was fascinated by Dr. Mallett when when I heard him speaking on a local radio station here in Connecticut. It was the first time I had ever considered the possibility that either rotating matter or energy could be used to stretch or...

    Expanding universe

    1). The only type of time dilation that I am aware of is due to relativistic effects, such as the the slightly slower frequency of clocks at rest in a gravitational field when compared to clocks in free fall, or the slightly slower frequency of clocks, when travelling at great speed relative to...

    Speed of gravity

    In his book The Fabric of the Cosmos, Brian Greene writes, "Einstein was able to work this out, " and he found that the speed at which gravity can transmit it's influence is exactly the speed of light. "...the warps and ripples-gravity, that is-do not travel from place to place instantaneously...

    Brane Movement Causing Gravity

    Accelerated Brane I don't think a brane which has constant velocity could be stretched by an inertial mass for very long. The mass landing upon it would eventually attain the same velocity as the brane and, I must assume a stretched brane would eventually return to it's un-stretched original...
