Time, an illusion?

Question

Many physics are of the opinion that the linear perception of time we have is an illusion. Does this mean the future and the past is here and now?

Does this mean the future is deterministic? Only we cannot see it?

Answer 1

Well, time has no shape. It doesnt exist at all. Its just an imagination that we use to help us through our daily life. One could say, "well we have clocks and clocks measure time"
Clocks in fact do not measure time, we define time by what clocks measure.
The physical world goes on with or without the idea of time. It doesnt exist, but it sure does make our lives easier.
Time is not a NATURAL feature of the universe but simply a concept invented by our species to separate events into past, present and future. There is no Cosmic Master Clock that keeps track of absolute, universal time. There is no physical "past" trailing along behind the "present," nor any physical "future" waiting up ahead for us to get there.

Answer 2

Parse your question for meaning. The past is not here now because "here" refers to location in space (not time) and now, by definition, means the present only. As a certain conservative commentator once said, "Word mean things". Take it to heart.

As for the future being deterministic, no that is not the current view of modern physics. Quantum mechanics is a probabilistic theory, meaning only the odds of some future event is determined now. Furthermore, this is an intrinsic feature of the theory, versus a limitation on what happens to be known at the time (like, how many fingers am I holding up?).

Answer 3

There are lots of different trains of thought on the matter.

In one way, since you will only experience one future, and only one instant of time at a time (so to speak), the future is entirely determined, you just can't say what it will be like, no matter how well you know the present.

Others say that the future is undetermined and is a whole set of possibilities, and becomes determined as decisions are made, and random events happen.

Many physical processes can be described equally well without reference to time, using it merely as a handy parameter. Much of physics doesn't treat a time variable any differently from a spatial variable - we just only seem to be able to move in one direction along that variable.

Answer 4

Yes! Thanks for asking.

The easiest way to interpret this is to see yourself outside of the entire universe and time. Try to see the entire existence of the universe over time as a magnetic tape of which the read/write head is your consciousness and determines your place in time.

The fact that the tape exists means that the past and the future (ahead of the head) are there.

If you would be able to place the read/write head to another spot of the tape you would have time traveled.

The read/write head is reading the contents of the tape and adjusting it to its will (that is YOU) having changed the contents for the other read/write heads that are present after you.

Imagine billions of read/write heads working on this tape all slightly dislocated from each other.

Do you now realize how powerful you are? You are changing the future for others behind you.

Answer 5

The way most people perceive time, it is an illusion, we invented clocks to measure time but they do not do this. Time is nothing more than an interval between events and events occure because of motion, no motion, no time.

Answer 6

time is a constant
it is a perpetual force in nature
and only split into manageable units such as hours minuets etc
