• Re: Astrobiology and Extremophiles in Rain Every 19 months we get a lineup with a very nearby Venus, and solar
  winds of typically 400+ km/sec are in fact capable of transferring
  microbes and spores from those upper clouds of Venus.

• Re: Mutual "length contraction" in Euclidean geometry In some frame of reference, you locate the 'events' at the endpoints of a
  rod (say) at the same time (i.e. with the same time coordinates), then take
  the spatial distance between them. That is the length of the rod. Were you
  unfamiliar with that concept?
  To determine the proper length, simply take the spatial distance between the

  stationary system, and the time now defined being appropriate to the
• Re: Universe to expand FOREVER! I tend to agree with the "no center theory" listed above.
  However,
  It's much easier to say that the universe will expand forever
  than admit that one will never be able to trace back every
  single conglomorating mass event that took place everywhere
  the universe for all time, and why shouldn't it?

  As I was leaning toward "identity line", I did a Google search for

  "1:1 line": 16,800,000 entries;
