I have no hope that you understand that this sentence do not even make
sense without you specify relative what this ***** absolute rotation
*** will occur.

Afterall you are a very primitive bot, maybe the most primitive.

Your answer it just loads of hogwash and i am pretty sure you are
aware it do not answer anything.
You are now down on the simplest bot level that of reharshing
meaningless citations out of context.

Good luck.

"‘Now, it is very remarkable that this is so extensively overlooked,’
continued the Time Traveller, with a slight accession of cheerfulness.
‘Really this is what is meant by the Fourth Dimension, though some
people who talk about the Fourth Dimension do not know they mean it.
It is only another way of looking at Time. " H.G. Wells 1898 'The Time
Machine'

It would be a rare situation where a precept which existed in a
science fiction section of a bookstore in the late 19th century was
expressed as a supreme human intellectual achievement in the 20th for
breaking the boundaries by allowing fiction to gain a foothold
diminishes us all,not just the idea that it is possible to contend
with fiction but also the very process itself used to justify or
contend things like 'time travel' come under the same type of
handling.

The great poets and prophets of our race often expressed things in
fantastical form and especially those things which bridge intuitive
and intellectual enjoyment,things such as music, all great art and
even understanding of nature but never did these people ever try to
propose their fictional forms as fact.The ideology of human control
over time is a powerful one that plays to our memories,our curiosity
for the future and approval from people of the past but the sentiment
belongs in the fictional novel from which it came and where it
belongs.

The great mysteries are all there inside a person inasmuch as he
allows the enigmas to move freely between the individual and the
Universal,the temporal and the Eternal,art and life,the terrestrial
and the celestial rather than projecting childish novelties into the
Universe ,hence -

"When I was a child, I used to talk as a child, think as a child,
reason as a child; when I became a man, I put aside childish
things.For now we see through a glass, darkly (enigmate in the Latin
of the Vulgate); but then face to face: now I know in part; but then
shall I know even as also I am known." Paul

Huh? You probably need to check your algebra more carefully before
claiming the formula increases "exponentially."

Everybody knows that if you have a quantity that depends on only one
variable, then if you increase the variable linearly, then the
quantity must also increase linearly. Everybody knows that.

Like in d=(1/2)gt^2, where there is only the variable t. You increase
the time linearly, and the distance must increase... whoops.
