I don't. I am equating one bit with a volume of space about the size of a proton. The actual number of baryons in the universe is smaller, about 10^80. If you squashed the universe flat, it would form a sheet about one proton thick. But I am also pointing out a coincidence (or not) of physics. But you will note that the volume of the universe is proportional to T^3, not T^2, so if the relation is not a coincidence, then either the properties of the proton or one of the other physical constants would not be constant. And BTW I agree that we cannot prove or disprove that the universe is a simulation. -- Matt Mahoney, [EMAIL PROTECTED] ----- This list is sponsored by AGIRI: http://www.agiri.org/email To unsubscribe or change your options, please go to: http://v2.listbox.com/member/?list_id=11983
