Is the universe a perpetual motion machine?

I don’t think so because there is a loss of energy due to entropy. I’m not a physicist, and I very much could be wrong about this.

The question then becomes the universe’s motion relative to what? One might stipulate that the universe “moves” through time. The concept beautifully explains gravity as a matter of geometry rather than force.

@stanleybmanly The multi-verse.

Good one! And a convenient way out.

No. Ultimately entropy will cool it to almost absolute zero as it expands to infinity and the fuel is used up.

Perpetual motion machines aren’t possible as some energy is always lost to the environment. The universe as a whole cannot lose energy in this way as there is nowhere for it to go. In that sense the universe is a perpetual motion machine.

At the moment the Universe is expanding at an accelerating rate. Scientists don’t know if this expansion will continue or if the Universe will reverse direction and crunch together. Link

According to Berman,LanzaRobert in the book:

The Grand Biocentric Design

where this question was addressed.

He stated the the Universe IS expanding according to what we as humans think it as.

He goes on to state that our minds created everything, hence the Universe as well.

The more discoveries and theories are thought of the more it expands.

He was more explicit in the explanation but the above was just my summation of his

statement of what i got out of it.

@LostInParadise If there is an eventual contraction, does that mean mass/energy must be conserved and the aggregate entropy will be recaptured somehow?

I don’t know. Contemplating the Universe seems to give two possibilities, neither of which is easy to conceive.

The first is that the Universe had a beginning. But how could that be? There must at least have been scientific laws before the Universe came into being. If the Universe had a beginning, will it have an end? But then what?

The second possibility is that the Universe did not have a beginning, that time in the past extends infinitely far. It is intriguing to imagine, but difficult for me to get my head around. If the Universe continuously expands and contracts and if there are only a finite, though extraordinarily large number of possible Universes, does that mean that mean that everything that happens has happened infinitely many times before?

@LostInParadise

Yes.

I read somewhere in my world of books that all has already happened.(Book of Enoch).

Predestination is a possibility to consider as in :

The Books Of Enoch by Joseph B. Lumpkin
( however I only purchased this one as it summarizes the next two books as well.

Now considering obtaining the other two , since this book has a Hebrew slant.

The Three books listed are:( in case others on this site wish to know more)

The First Book of Enoch ( The Ethiopic Book of Enoch)
The Second Book of Enoch ( The Slavic Secrets of Enoch)
The Third Book of Enoch ( The Hebrew Book of Enoch)
