Of course, some people/corporations will make arguments relating internet to delivery services -- paying more for overnight shipping means you get the package/letter faster. Of course, this is a flawed argument for myriad reasons, not the least of which is that if someone mails me an overnight letter I don't then have to pay extra to receive it...

Good point. I think, though, that they approached it completely backwards: they have presented a method for determining the information-theory voxel size of the universe (or whatever you like to call it), NOT the energy density, as TFS claims. That is, I think they should have started with the correct answer (10^-27 g/cm^3) and derived the voxel size from there. Then we could debate on the physical meaning of this voxel, which is a legitimate thing to talk about.

No, I think this information theory "approach" uses 10km^3 voxels:

Specifying the location of the 10^25 stars in the visible universe to an accuracy of 10 cubic kilometers...gives an energy density of about 10^-30 g/cm^3. ...But if the location has to be specified to the Planck length, then the energy density is about 117 orders of magnitude larger.

So they roughly recover the quantum mechanical (apparently incorrect) result if they use Planck length^3 voxels.

Not that I read the article of course, but this seems an odd thing to do, as you should probably be confining them to hbar units of phase-space, not just confining them to voxels.

It boils down to solid angle per pixel -- sit close enough to a huge screen and you'll be able to tell the difference.

I could imagine absolutely humongous curved screens being really cool -- the periphery might not contain any information relevant to the plot of the movie, but it would make for a very immersive experience. I call it the 4pi steradian display...

Exactly how many nuclear disasters does it take before we figure out how to do what these other countries are already doing?

Nuclear energy is just about the safest form of energy: http://www.forbes.com/sites/ja...

Energy is really, really dangerous, end of story. Nuclear is somehow the "scariest," but not because it's statistically more dangerous.

Solar's production curve does not match the peak user curve of electrical power.

Although I think in some places (e.g., Los Angeles) it does match fairly well, as air conditioners use a lot of juice. But I completely agree: nuclear is a terrible form of energy...but it's better than most alternatives.

If this is timesharing, give me my share right now.
