Quantaping!...............

so no heat...

Time Travel?

If Lucy Preston is going, sign me up.

I’ll trade you my Dilithium Crystal for your Time Crystal.

Unless these ‘time crystals’ power the laser that holds them in state, this apparatus consumes energy just like any other natural process.

Thermodynamics:

0. There is a game (consequence of zeroth law of thermodynamics)
1. You can't win. (consequence of first law of thermodynamics)
2. You can't break even. (consequence of second law of thermodynamics)
3. You can't even get out of the game. (consequence of third law of thermodynamics)

“The consequence is amazing: You evade the second law of thermodynamics,” said Roderich Moessner, director of the Max Planck Institute for the Physics of Complex Systems in Dresden, Germany, and a co-author on the Google paper.

Huh. The guy found a loophole.

In Quantum Physics those ‘rules’ don’t apply.................

so no heat...

Not this time...

Time crystals will soon become politicians. It’s their nature — forever flip-flopping.

[Yardstick]

I don’t think the advantage is that using them doesn’t require energy but that they don’t generate heat when they change states. So any heating can be “externalized” to the part of the system that’s powering the crystals but the crystals themselves won’t produce heat. That’s my stab at it, anyway.

The eternal cyborgs at the end of time rejoice that they will be able to see the heat death of the universe....

I’d like to hear a physicist’s explanation of how the crystal states can be “observed” with no energetic interaction. If the crystal is not emitting energy, and we aren’t bouncing some wavelength off the crystal (which would affect it), how do we measure the state of the crystal?

Heisenberg tells us observation is interaction.

[M Kehoe]

Well, what are they going to use it for?

Transporters?

5.56mm

Schrodinger isn’t sure....................

So...The cat dies, comes back to life, dies, comes back to life , etc, but never scratches the side of the box or collapses to the bottom?

One point twenty-one gigawatts?!? Thanks Red Badger.
