Onifire, both are attributes of energy, so yes, they are something that can be said to exist, they are part of the behaviour of energy.
I suppose it ultimately comes to this fundamental question,:- If you travel along with a quantum of energy, where is time?
The answer is that it is not there.
It is not there because time is not an attribute of energy and because time is not an attribute of energy, it can have no physical properties to manipulate.
This means that time cannot truly effect energy and energy cannot truly effect time.
When I see the word "energy", the definition I'm used to is "the ability to do work".
What definition of "energy" are you using?
Spacetime" is the measurement in relativity, the measurements are relative to the state of the observer making the measurement.
But!
This does not objectify space or time and turn either into an object.
They are useful ideas of measurement, but remain only ideas.
That time can be
dilated shows that it is more than just an idea, that it is, in fact, a "thing".
If we fail in distinguishing between 'idea' and 'thing' we can never develop a true insight into the cosmos,we relate to ideas all the time, but treat them as things, but this does not make them objects of reality.
Last time I checked, the people who realize that time is a thing are the ones who are developing a true insight into the cosmos.
Regarding time as an idea has gotten us what?
Science fails to recognize the single most potent element of human existence.
Letting the reigns go to the unfolding is faith, faith, faith, faith.
Science has failed our world.
Science has failed our Mother Earth.
