Yes. Less energy would be extracted from the system than otherwise.

Somewhat. Similarly all events would be connected, regardless of when or where they took place. However they cannot all be causally connected as per relativity.

I would say that it is something. Without it everything happens at once and in the same place.

No wonder it hurts when it hits you straight into the back of the eyeballs!

I like this idea IA. As long as the foam is fully saturated you are only dealing with the shock wave. And if it is not quite fully saturated much of that would be reduced without excessive pressure differential (other than the shock wave). A good time to fine tune this would be around breakfast time with a large family. It might break the yolks but not the shells.

Tension can point toward the centre but depends on the structure as well as the external forces.

If the strings all meet at 120 degrees the static tension would be all equal, though I suspect waves on two of them meeting at the apex simultaneously would not completly constructively interfere down the third string but also have two secondary waves rebounding back down the two original strings.

And of course the equation still holds, the coefficient may change, but usually not by much for the reasons you mention.

Or just look at them. If one of the blocks is a ball you have found the odd ball.

Should we just call an electron a wave also, and leave it at that? I know there is a difference, to a degree, but reduced far enough there is no particle aspect left (I think?), yet both have some particle like properties that emerge from the "wave".

I didn't even see it coming!

If you are in a space station being spun to make artificial gravity and run real fast you would decrease in "weight" going one way, in which case at some point you could jump just right and hover above "ground" unable to reach anything, or increase in weight if you ran in the opposite direction.

Can a second set of wheels be triggered to come into play on picking up the object that are geared to be in reverse? They can already be spinning in reverse but not touching the ground and the initial wheel set can continue spinning forward but be lifted off the ground.

I picture this as being borrowed from space itself which is a quagmire of energy fluctuation. Anyone see pitfalls in this idea?

Throw in any friction calculation and the resulting distance is shorter for the given time.

And on the seventh day you deserved a good rest!

Wouldn't they all be stretched the same amount but, due to the extra distance of anything more than X lightyears away (X being the time since creation), the light from those sources simply would not have arrived yet?

Isn't the alpha centauri, our nearest neighbour, a 2 or 3 star system. If we aren't part of that how could we be a binary with something else.?

Maybe Spaghetti Theory will take over String Theory (Macaroni metrics, Lasagna branes etc. etc.)

I'm pretty sure if you include the uncertainty of the demon himself he cannot get an edge over random statistical variances. (someone summed up the laws of thermodynamics as "You can't win, you can't break even, but you must play the game")

Other than the CP conservation violation Swanton mentioned. Forgot where I ready this but if you are off galavanting around the universe and meet your "twin", and he offers to shake your hand, if he offers the left hand don't shake it!

I think we conclude otherwise, but wonder how it came about. AFAIK "every particle has an anti-particle" refers to the type of particle not the quantities, although any new production of one must be balanced by the other. Isn't there also a small "flaw" in the conservation law that in theory biases matter over anti-matter?

IIRC it is based on the uncertainty principle. On the scale the demon needs to operate he can't have the information he requires.

At the size of the Demon it's not pressure, just momentary impacts. Also will not work according to Quantum physics. The thought experiment demonstrates the statistical nature of the second law.

Yes, and entropy increases but not by as much as if you had used a conventional electric heater at "100%" efficiency.
