I'm a post-doctoral researcher with a wide range of interests. My career is in complex systems science (or maybe cybernetics) and the origins of life, but I also have research interests in

  • the foundations of statistical mechanics and its relationship to information theory
  • Earth systems science
  • non-equilibrium thermodynamics in general

I'm also generally interested in the foundations of quantum mechanics and in black holes, though I wouldn't say I'm an expert on those things.

It's probably worth noting that despite the fact that my research is in physics-related areas, all my degrees are in other subjects. If I occasionally seem to start talking in an alien language, this is probably why.

comment A Cosmological horizon at the Hubble radius?
I'm not sure but I think a relevant observation is that in order to keep $D$ fixed, the clock at the other end would have to accelerate in order to overcome the expansion of space. I suspect that the time dilation you calculate is actually associated with this hypothetical acceleration. An object at the Hubble distance would have to maintain an infinite acceleration to remain at a constant distance from us, and would therefore experience infinite time dilation.

This is the physics and astronomy stack exchange. The history of astronomy is part of the subject of astronomy. Voting to leave open. Please do the same.

comment Is it necessary to consume energy to perform computation?
@Trimok it's simpler than that. You add $Q=k_BT\ln 2$ joules of heat, so the environment's entropy changes by $Q/T=k_B\ln 2 = 1\,\text{bit}$. The environment is typically assumed to be a heat bath, so we don't worry about its free energy, just its entropy. The total entropy change is $-1\,\text{bit}+1\,\text{bit} = 0$, satisfying the second law.
