Time crystals: They require energy added back into them?

I was initially under the impression that time crystals are in lowest energy state and neither gain or lose energy. But other sources suggested they might require a bump in energy after a while to keep going?

What are "time crystals" ?
It takes energy to get a crystal oscillating.
Depending on how they are mounted, crystals can oscillate with a very high efficiency.
That oscillation can be maintained with very little added energy.

Time crystals. Not that I know the answer to the question, but I do know how to google

The wikipedia page linked by Filip says, in the introductory paragraph, that time crystals have been realized in periodically driven systems. I don't know where OP gets "bump in energy," but if it takes periodic driving to create a time crystal, then energy is at least being used to maintain the driving system.

The OP has a history of poorly sourced/referenced posts. In this case,

Are of course impossible to follow up on.

The OP in this case is so badly presented that I can't tell if he's really talking about "time crystals" or "crystals in an oscillator used to measure time."

The question cannot be important. Since that posting, the OP has not logged back in.

It seems the answer is both yes and no, and no and yes, depending on the application of, and the meaning of time crystal.

Looks like he fooled us again.

He/she earned an “Ignore” from me.

Yes, this is the time crystal I am referring to. And the only reference I can offer to needing to add energy to the system is from a YouTube video which I'm told isn't a good source, so I didn't include it.

So you knew that your source was unreliable, tried to hide it and post anyway?

Why don't you find a reliable source? Then we can discuss it intelligently.

In other words, you don't have a valid reference as a basis for discussion. Thread closed.
