What is time?

Do we even know? After looking around on google i don't see many answers that give a clear definition of what time is. Is time our 3 dimensional universe's movement through another dimension? I also cant get a good clear definition of "what is spacetime" everything just says it's a combination of space and time. well I fucking get that, but what does that even mean?

You're trying to get an intuitive and scientifically accurate answer at the same time. This doesn't exist, if it was intuitive it wouldn't have taken so long to work out.
Time is a property of the universe. Time is relative and depends on your energy. Time increases large scale entropy, and conservation of entry is an aspect of time. Time is not a dimension and it is tired to space, you can't separate them.

I'm sorry, cutting edge physics concepts like the nature of time are only really useful through equations. Our monkey brains were not built to understand the fabric of the universe intuitively.

No it doesn't. Quantum decoherence increases entropy. Time is only relevant because wave functions evolve in time.

Real things don't have good definitions. The definition helps you use the word: it's not a substitute for experience.

There are some who disagree and define time as a continuum of incidents from past to present to future. Not linking the source, it's easily found. What is that if not time?

Time is an emergent property of 3D space travelling with a constant velocity (what we call speed of light) in a higher dimension. The "friction" against this higher-dimensional "medium" is slowing matter down and is responsible for the emergence of mass.

Massless particles do not experience time because they don't interact with anything. By moving in the opposite direction of the movement of space within higher-dimensional "medium", from the perspective of the latter they are essentially standing still. As soon as they collide or interact with something, they are "nudged" slightly against the "medium" which makes them no longer travel at the speed of light (and no longer be massless) for a limited duration.

You can't appear to go faster than the speed of light within our 3D space because if you could, you would GAIN mass as a result of relative motion against the "medium" (now in the opposite direction), and you need to LOSE mass to appear faster. This impossibility of "faster than the speed of light" is equivalent to the impossibility of "stiller than absolute stillness". In fact, depending on frame of reference, these two statements describe exactly the same thing.

However, "moving faster" than the speed of light IS possible in higher-dimensional medium. As stated previously, by going faster than the speed of light you GAIN mass because you start moving relative to the "medium", but in the opposite direction, which is exactly what antimatter is doing.
Matter-antimatter annihilation is simply their speeds cancelling out and becoming equal to speed of light – zero.
Why is there more matter than antimatter? Because our 3D space travels uniformly with a constant velocity as a single unified object – everything around us moves in the same direction through the "medium", so we perceive it as matter. Outside of our moving "bubble", however, nothing stops arbitrarily large quantities of "antimatter" from existing.

From my dogshit understanding time is a matter of observation in consensus reality, and it's a matter of motion in physics. If you have to ask if that implies a physical time dimension, that's a matter of observation.
You can't have time without space, because a relative system with a single scalar would be immutable without space so there's no need for time; and likewise you can't have space without time because that can be just as easily represented by a single immutable scalar, insomuch no system exists without having both or neither because in any other circumstance you would just have a more complex identity of a possible simpler one - unnecessary.
'Spacetime' in terms of physics, which I also don't understand, might be analogous in some ways to the EM field or at least I'd imagine it would be. Since one justifies the other, an effect on gravity will have an effect on time, and vice versa.

It is the dimension that frames sequential movement of objects and energy in 3d space.

Absolutely wrong. Time is the temporal dimension.
