The true perpetual motion machines

I have no idea. It merely seems convenient, and explains many things accurately enough to be taken as fact. It also corresponds with the other constants we see

Actually, I think his mother was a hamster. That smelt of Elderberries.

I agree.. but I have a question. If small enough, how could you measure a Planck unit of distance (assuming you could have a measuring device)?

 

Technically such a measuring device is impossible.

 

the same way we know the wavelenght of red, blue or any color.
we do not have micrometers that will measure it directly.
we use an indirect method

 

Well, what I mean is that if I were small enough and had a small enough ruler, would I be able to see this distance? How does it differ from zero units? Couldn't I see a distance smaller than a Planck unit?

 

Does this really happen? As in, the smallest unit of time being 10^-43 seconds?

 

Agreeing with JamesR is in the same league as being buried alive with a Gillian fire ants, but, he nailed it.

There are theories that the smallest unit may be smaller than the Planck unit, but the principle is the same: the alternate theories speculate that there is a smallest unit, and the next smallest unit is zero.

Whereas Newton's calculus allows the hypothesis of unlimited smallness, the quantum physics based ideas speak of a specific smallest actual unit, and the only smaller unit is zero.

 

Well that is how I was thinking of it, however I was trying to get the answer in a round-about way to hide my ignorance.

So basically, say the unit of distance is 1 for the Planck, then that means either I move 1 unit at a time or zero? I cannot move 1/2 a unit? That's pretty damn cool. Makes me re-think Zero's runner paradox

Absane:

You got it. According to quantum physics, there is some specific smallest distance possible. Half of it doesn't exist.

Consequently there is supposed to be a smallest time interval possible. Half of that time can't exist. Next smallest time interval is zero.

At one time, the smallest distance was the Planck distance and the smallest time interval was called the chronon.

 

As we like to oversample, for accuracy, is this possible? We always try to measure an object using a smaller wavelength than the object, so would it be possible to construct apparatus that operated in a smaller timeframe, than the event it was trying to observe?

 

A machine driven by gravity could give the illusion of perpetual motion.
