Is time an actual thing?

Time is a prime conflict between relativity and quantum mechanics, measured and malleable in relativity while assumed as background (and not an observable) in quantum mechanics. To many physicists, while we experience time as psychologically real, time is not fundamentally real.

What do people mean when they say time doesnt exist?

When physicists say that time doesn’t exist they mean one of two things: 1) The passage of time is an illusion, or 2) Time isn’t fundamental. We can only form memory about things from a time where entropy was smaller, so we can’t remember the future.

Does time really exist?

Indeed time does not exist , but that is because time is how we perceive entropy. Everything is only “now”, the “future” can never exist until it happens unless the universe is deterministic, in which case the future is fixed and always exists and the present is merely an illusion, such would be the case if we are a holographic projection on an event horizon, for example.

Why is time not real?

That assumes time is not real. Some people believe that it is not real because we “invented” time with clocks and sundials, because we wanted to keep track of the day-night cycle on Earth. They think there really is no thing called “time” and things just “happen”.

Can time exist without space?

Time cannot exist without space and the existence of time does require energy. I have a theory in which space, time and energy – all three simultaneously pop out from what I call the unmanifest. This is a level of existence which is one step deeper and beyond the zero point energy level with a non zero mass gap.
