A friend of mine regularly goes over theories with me about the existence of the universe, other dimensions,…. Most of them seem quite logical and possible to me, but he also said the following, which confused me: He said that the universe is a four-dimensional makes movement in hyperspace that we experience as time. This time is propelled by a certain energy. The speed of time is equal to the speed of light, so the maximum possible speed, and thus determines the energy of particles. That particular energy that drives time is therefore also equal to the total energy in our universe.
You would have two groups in the universe: – energy (matter and free energy such as light and gluons) – forces caused by “time”: the expansion of the universe (he assumes that the universe is a ‘dimensional hypersphere that inflated as it were) and gravity.
With the particles (energy) the law of conservation of energy is quite simple: energy is converted into another form of energy with no loss or gain. Energy can arise and disappear in interactions of energy and time. Yet energy arises from “time” which is constant. As a result, the speed of time and with it the energy of every particle in the universe decreases. But that “information” would travel at a finite speed (possibly the speed of light) causing it to first decrease around energy, causing a “dimple” in space-time that we experience as gravity.
I know this sounds pretty unlikely to be true and I wouldn’t believe it if I were reading this as an outsider, but please think about it. He is not a boy with too much imagination even though this may be wrong, he is really a genius (he taught me quantum mechanics when he was 12, which I didn’t understand at all at the time). If this is correct, I personally think that science should know this.

arne,
buy/read the book “The unraveling of the cosmos” by Brian Greene (Dutch translation).
It indeed states that there is an ‘exchange’ between energy (speed; acceleration) and time: at very high speeds (close to the speed of light) there is a very high ‘motion’ through space and a much slower ‘motion’ through time. . A stationary object, on the other hand, experiences everything as movement in time, and none through space. An experiment is described in which the elapsed time on an atomic clock that has flown at (relatively) high speed around the globe is compared with the elapsed time on an identical atomic clock that has remained on Earth. Although the difference in elapsed time is minimal at this (yet still slow speeds due to the speed of light) speed, there is a measurable difference !!
Exciting!
