Motion-energy, Motion-time, Time-energy, Space-time-energy?

Question

Is energy necessary for motion? Can there be time when there is total absence of motion (absence of motion ---> absence of sequentiality)? Is energy necessary for time if it is necessary for motion and motion is necessary for time? Can there be energy or time without space? In the end, is space the prerequisite of creation? Thanks!

Answer 1

Motion is relative: whether something's moving or not depends on your point of view. One could say that the Earth is not moving except for rotation, or that the Earth is moving but the Sun isn't, or even that the Moon is what isn't moving. However, motion does require the presence of matter, and matter is a form of energy, so without energy, there can be no motion, though it's not for the obvious reason.

As for whether time is possible without motion, this one's harder. If there is any matter in the universe, you can always assume some of it's moving, which would give you time, but if there isn't any matter, the universe is empty. I say there's still time: the fact that there's no matter in the universe doesn't keep a person from finding out what the universe will be like or was like. So if motion isn't necessary for time, energy probably isn't necessary for time either.

But for your second-to-last question: that'd depend on just what you mean. If there is a universe, but it has no space in it--its size is zero--then time does still exist, as you can probably tell what the universe was like and what it will be like given how it is. If, however, there is no universe at all, there can be no time, as there isn't even a "state of the universe right now", much less a "state of the universe yesterday" or "state of the universe in a few years".

So, is space the prerequisite of creation? Not if you can create more space! :-)

Answer 2

Linear, constant speed motion does not consume energy.
Except if there is friction.
Motion is a relative term. It depends on the system of coordinates it is referred to.
Also time is relative and depends on the reference coordinates.
If you travel on a train, for you the whistle has always the same pitch. If you are standing in a station the pitch of the whistle changes when the train approaches and when it leaves. Likewise your time will be different from the time experienced by who is standing at the station. Faster when you approach, slower when you go away. Of course time variations would be noticeable only at speeds close to the speed of light.
Time, space and motion are inter-related. But they are not absolute. They are meaningless unless referred to more than one object. To measure space, time and motion at least two objects are needed.
I am unable to answer whether and how space and creation are related, but I would say that the creation comes first or they are simultaneous..

Answer 3

In the end space-time is the prerequisite for creation.

Answer 4

They're all interconnected...but energy is more dependent on space and time than the other way around.

Answer 5

there grow to be no time in the previous the universe. So mass is critical for time. at the same time as there is mass, there is power. AND we require an area to placed this mass in, so area too. action is oftentimes basically to guard power, or angular momentum, yet yeah it is critical too.
