Going back in time… With no change…

We cannot reverse the arrow of time any more than we can erase all our wrinkles or restore a shattered teacup to its original form.

Or can we?

An international team of scientists led by the U.S. Department of Energy’s (DOE) Argonne National Laboratory managed to return a computer briefly to the past.

To achieve the time reversal, the research team developed an algorithm for IBM’s public quantum computer that simulates the scattering of a particle. In classical physics, this might appear as a billiard ball struck by a cue, traveling in a line. But in the quantum world, one scattered particle takes on a fractured quality, spreading in multiple directions. To reverse its quantum evolution is like reversing the rings created when a stone is thrown into a pond.

In nature, restoring this particle back to its original state – in essence, putting the broken teacup back together – is impossible, since you would need a ​”supersystem” to manipulate the particle’s quantum waves at every point. The time required for this supersystem to properly manipulate the quantum waves would extend longer than that of the universe itself.

The team managed to overcome this complexity, at least in principle. Their algorithm simulated an electron scattering by a two-level quantum system,​ “impersonated” by a quantum computer qubit and its related evolution in time. The electron goes from a localized, or​ “seen,” state, to a scattered one. Then the algorithm throws the process in reverse, and the particle returns to its initial state – in other words, it moves back in time, if only by a tiny fraction of a second. (1)

Going back in time.

By returning to the original state.

Because time is defined by change.

But what does this mean?

This doesn’t mean they go back in time.

But that time wasn’t there in the first place…

The 2nd law of thermodynamics.

The arrow of time.

The fate of the universe.

Everything will be back to their original state at the end.

And the end will be the new beginning.

Going back in time.

Where time is nothing but a fleeting feeling.

Open your eyes.

Can you dream of how you started dreaming?

When? Where? (Why?)

In a UCI study, participants sat with their heads inside a high-resolution fMRI scanner while watching a TV show and then viewing still frames from the episode, one at a time.

The researchers found that when subjects had more precise answers to questions about what time certain events occurred, they activated a brain network involving the lateral entorhinal cortex and the perirhinal cortex. The team had previously shown that these regions, which surround the hippocampus, are associated with memories of objects or items but not their spatial location.

“Space and time have always been intricately linked, and the common wisdom in our field was that the mechanisms involved in one probably supported the other as well,” added Maria Montchal, a graduate student in Yassa’s lab who led the research. “But our results suggest otherwise.” (1)

Trying to remember then when.

Without caring about the where.

But nothing of these matters.

Because no matter how precisely we recall where or when something happened in the vast dark forest of existence, we will still not be able to answer a much more fundamental question: How did we get in that forest in the first place?

In a cosmos with time, there is no forest.

Nothing but a constantly changing set of beings.

Changing to show that there is nothing to change.

What a weird cosmos…

In a world of change, time has meaning.

But in a world of change nothing is real.

Feel the breeze…

Without any trees to linger in the air…

Time cannot flow.

And without a breeze blowing between the trees…

There are no trees.

Feel the breeze…

Don’t try to explain.

Just…

Feel the breeze…

Time. Universe. Timeless…

According to a new interpretation of general relativity, the Big Bang wasn’t the start of ‘everything’. Based on a new model, some scientists showed that as we rewind time back to the beginning the universe does not diminish into a singularity, but at something the team call a Janus Point, named after the Roman god with two faces. The relative positions and scales of the stuff that makes up the Universe effectively flatten into a two-dimensional pancake as we rewind time. Passing through the Janus Point, that pancake turns 3D again, only back-to-front. (1)

A timeless world. Breeding time into the void of space.

An eternal universe. Breeding timelessness into the cosmos.

At the end, what matters is not time’s existence or inexistence which matters.

You are not a timeless being, neither are you bound to the seconds passing.

Even the negation of something implies its existence.

Care not about anything outside you.

And you will discover that there is nothing there.

Except the things you bring with you.

You can never walk into the same river.

And yet, you can talk about that river.

At the end, what matter is not the river at all.

But the vast forest around it…

Telling time…

In music, sports and other activities, we calculate movement in two different parts of the brain: One type of anticipatory timing relies on memories from past experiences. The other on rhythm. Both are critical to our ability to navigate and enjoy the world, and scientists have found they are handled in two different parts of the brain. (1)

But there is nothing in the past.

Everything is now.

Here, living with you.

Destroyed the very moment you stop thinking about them.

But there is no rhythm.

Everything is in and out of sync.

Within the soil, with the worms eating the earth.

Up in the stars, within the galaxies and through the cosmos.

The cosmos is dancing.

Only if you listen to the music.

You can see the past and the rhythm if you believe in time.

But you will never see time if you see the past and feel the rhythm.

For it is then that you will realize that there is nothing which passes by, only things which are. A dancer does not expect the end of the music. He just moves in thin air with the expectation of eternity in his every step. A dreamer does not feel that those beautiful moments have passed. He just cries smiles with the firm belief of eternity in his every tear.

Look outside the window.

There is rain pouring down.

Why do you smile then?
