A Perpetual Motion Machine?

This, "a break in the symmetry of time" , explains a lot about some of the episodes I had in my mis-spent youth, last week.

It's way over my head, too.

He has no idea what he is talking about. Here's what time is like:

Time, explained by an expert.

That's more like it.

Well I guess atoms are perpetual motion machines....and we do know how to get a surprising amount of energy from them....The problem has always been scaling up eh?

Everything is in motion anyway. So "perpetual motion" already exists everywhere. A "perpetual motion machine" though, implies something that could supply energy for ever, and that is regarded as impossible simply because extracting energy must deplete the source of the energy. It's not just physics, it's common sense.

Just because something (or even seemingly everything) is in motion, doesn't confirm 'perpetual motion'.

Perpetuity isn't something you can wait out.

I will suggest that in order for motion to have an effect or otherwise be of consequence or noticeable, either:

generating the change or signal will cost energy, thereby eventually slowing the object

or

the motion will be realized by a variation in the expected action in a process that adds energy to the system....in which case it doesn't qualify as perpetual motion, since energy was added.

.

If you think the universe is below a certain mass ratio, and that things will forever expand, there may come a time where everything is distant that information from various parts never reach other parts....at which point, what meaning would motion have without a reference?

.

If on the other hand you believe the universe is above a certain mass ratio, and we are due for a big crunch....If we are all reduced to a singularity, since singularity implies a single point without length or depth or height, doesn't that preclude any further motion?

That's like saying harnessed gravity, magnetism or the sun itself is perpetual, it isn't they are all just potential energy sources that are not ever lasting.

I would bet that sooner or later, the Uncertainty Principle will result in disruption of this process.
