Natural Science 301 Guidelines

This is an open forum area for all members for discussions on all issues of science and origins. This area will and does get volatile at times, but we ask that it be kept to a dull roar, and moderators will intervene to keep the peace if necessary. This means obvious trolling and flaming that becomes a problem will be dealt with, and you might find yourself in the doghouse.

As usual, Tweb rules apply. If you haven't read them now would be a good time.

    The article doesn't tell directly of time diverting.


    ‘In physics time-reversal symmetry is a mathematical operation of replacing the expression for time with its negative in formulas or equations so that they describe an event in which time runs backward or all the motions are reversed.’ - quote.


    In GR there is no absolute time, time dimension etc. There is spacetime.Time is something that is ‘perceived’ by particles.

    Time is only needed to describe that nothing happens anywhere at the same moment.

    Mathematical models give us singularities, for example, we cannot confirm it by any observation.

    Big bang, speed of light, spacetime singularity are concepts that are accepted, because the universe model description needs start points and limits.

    We are able to observe black holes, but the majority of theories and phenomena are not confirmed due to the extremes of such observations.

    Actually after doing more thinking Gravity doesn't always reverse if time is reversed. It gets seriously whacked. In the example above it seems to reverse right? But now imagine here on earth, you are sitting in your chair taking a nap. An hour later time reverses. But you don't suddenly get pushed out of your seat and fly off the face of the earth. Gravity is still holding you to your chair.

    But now imagine some rocks laying at the bottom of a cliff. Rewind time. They will continue to lie there at the bottom of the cliff for say 1 year, but then they will suddenly fly up into the air and attach themselves to the cliff! Gravity both works and reverses itself for no reason. Cause and effect becomes effect then cause. Reversing time messes everything up.

    You should read "Counter-Clock World" by Philip K. Dick.

    I do not believe that is what the article indicated. In fact, I believe it indicated Natural Laws remain the same..

    If one inverts time direction, the fundamental laws of physics still hold. That also holds for typical superconductors: if the arrow of time is reversed, a typical superconductor would still be the same superconducting state.

    "However, in the case of a four-fermion condensate that we report, the time reversal puts it in a different state," he says.

    "It will probably take many years of research to fully understand this state," he says.

    So what?!?!?! Your point?
