Time flows in One Direction

[Jason]

Physicists confirm that time moves forward even in the quantum world

For the first time, an experiment has confirmed that the laws of thermodynamics hold true even at the quantum level – which means that even in the quantum world, you can’t unspill that glass of milk.

The reason time runs the way it does in our everyday lives is because of the second law of thermodynamics, which states that over time all systems become more disordered, or increase in entropy. And that process is irreversible, which is why time only moves forward. But theoretical physicists had predicted that on the quantum level, the process might go both ways.

That’s because when you start dealing with really, really small particles, the laws of physics – such as the Schrödinger equation – are 'time-symmetric' or reversible. "In theory, forward and backward microscopic processes are indistinguishable," writes Lisa Zyga for Phys.org.

Now physicists led by the Federal University of ABC in Brazil have performed an experiment that confirms that those theories don’t match up with the reality, with thermodynamic processes remaining irreversible even in quantum systems. But they still don’t understand why that’s the case.

Sorry Dr. Who.

Time flow like tears, the policeman said.

My fanciful theory is that at the quantum level, space is like dominoes standing on end. It's pre-loaded, so that when one domino falls over, it tips the next one. That's why the speed of light is an absolute figure.
Have you ever noticed how those dominoes always fall at the same speed?

But once a domino has been tipped, it can't be stood up again. It can't be reversed. An increase in entropy is like an increase in tipped dominoes. Eventually, they will all be lying flat, and nothing can happen.

The basic premise is flawed. We can only experience time in one direction.
Ergo any experiments we do will come to the conclusion that time flow in one direction. Selection bias.

Rubbish. Time can go backwards and I can prove it.

Edit: Sorry, I meant prove it.

I would like to see One Direction flow in lava.

I always refer to them as 'Wand Erection'.

Yep, it flows downhill. Like shit.

You're joking right?

[Hermit]

Selection bias everywhere. We can only experience daylight between sunrise and sunset. Ergo any experiments we do will come to the conclusion that the sun causes daylight.

See how this works?

I always refer to them as 'Wand Erection'.

As a fan of homophones, I usually refer to them as "Wan Direction".

Either way, a waste of carbon.

Duration is the only important quantity in real world physics. All else is metaphysics...
