Thought for the Day


Scientists behind the Planck Mission believe the universe to be 13.82 billion years old. But given space was more dense during the early baryonic matter phase (roughly 47,000 years after Big Bang) and time slows down in high gravity, is that 13.82 billion years at our gravitational density, or 13.82 billion years of cosmic time? There would be a difference due to time dilation within high gravity - a measured second back then would be longer if observed from a present day gravitational perspective (not that it could).


Note that the above image is pre-Planck.

Just something to ponder while you're cutting the grass today.

  2. not so much a commplaint...but I noticed that the scaling of time was described at equal increments. Problem with that is, at the opening stage of the big "bang" is also supposed to be the beginning of time, but, at such high velocities (mind you, this is the same explosion that we are nestled in right now) the first space would be a micro inch, and grow from there.... ... .. .
    It is usually glossed over under shady speculative theoretical claptrap but hey. I failed Algebra in junior high...so, they may be right.
    But the time divisions should be marked to actual scale unless that's totally out of the question.
