Universe Has 100x More Entropy Than We Thought

Posted by kdawson on from the clean-up-your-room-that'll-help dept.

eldavojohn writes "Previous estimates are now thought to skimp on the entropy of the observable universe. The researchers contend that super-massive black holes are the largest contributor of entropy. Since they contribute two orders of magnitude more than previously thought, the total of all the observable universe is correspondingly higher. The paper highlights (in gruesome detail) new issues that arise with these new calculations — like estimating us a little bit closer to heat death (moving entropy totals from 10^102 to 10^104 out of a maximum of 10^122)."

    I propose a Fourth Law of Thermodynamics: There's more entropy than you think there is.

      Fourth Law of Thermdynamics: There's always more entropy then you think there is, even when you take into account the Fourth Law of Thermodynamics.

      I still wouldn't worry about the heat death of the universe, though, unlike those in the aforementioned link.

      You forgot to recursively account for the fourth law, you fool! The death of the universe will now be exponentially sooner every moment that passes!

    No, it merely reaches a state of equilibrium, so it never fires.

    I have also heard that "glaciers melting in the dead of night" contribute to entropy quite a bit.

    >>>What, if anything, does that mean for the past and future of the universe?

    There was a Doctor Who TNG episode about this. The universe at the point of heat death was a sad and depressing place to be... very very dark To paraphrase Marvin the Depressed Robot - Might as well slit my wrist now, since it will all end in tears anyhow.
