As Kurt Godel among others have said, time does not have only one dimension and one flow.

Einstein postulated that time was more like a river, ebbing and flowing depending on the effects of gravity and space-time. Even one second on Earth was not the same length of time everywhere in the universe.

He also mentioned that ‘now is an illusion’.


Newton and Einstein did agree that time moves forward.

Everything in the universe wants to move from low to high entropy, or from uniformity to disorder, moving to the almost random arrangement of galaxies in the present day. This is known as the “arrow of time.”


An incredible progress has been made in our understanding of time over the past century. From ancient time-telling sundials to modern atomic clocks, we can even track the passing of a second more closely than ever before.

The most accurate clock in the universe would probably be a rotating star like a pulsar, but on Earth atomic clocks provide the most accurate track of time.

Until we are out there and traveling the universe, we understand nothing of the outland unobserved. The nearest we come to understanding it is the Alice-in-Wonderland micro-verse we play around in. That particular map in small is closer to the territory at large than any other. 'Relativity' is myopic physics, which is why it is labeled "relativity".

Trouble is, you can’t anywhere except now.
Time is as perceived by an observer. What is now then for an observation?

When probability was introduced to the core picture of reality, no longer the universe was no longer deterministic.

When you are not looking, the wave function works according to the Shrodinger equation. But when you make a measurement, Probability(x)=I amplitude(x) I^2 (I-wave function).

The observation is in the superposition of the quantum particle state (human species also consist of quantum particles.

There are three essential components of the observed ‘now’ state.

Superposition: quantum objects can be in two different states at the same time. It was never actually observed (except double slit experiment).


Entanglement: after particles interact they become a single wave function. When we measure the state of one entangled electron, we know the state of the second one at the same time.

Measurement: postulate was added as a second set of rules to connect the math of quantum mechanics to what we actually observe. Single fraction of reality.

Lariliss, have you read "Endless Universe - beyond the big bang" by Steinhardt and Turok? If so, what do you think of it? I am just starting to read it.

Unfortunately or fortunately, I haven't. No personal opinion, but a potential to have a good time with a good book.
