Physicists Claim They Can Send Particles Into the Past

Can you really send a particle into the past? New Scientist published an article about this last week, and though I’m quite fond of the concept of retrocausality, I’m afraid to say that reality is much less interesting than fiction. Let’s have a look.

Retracting scientific papers is about to get several disorders of magnitude more complicated. Some papers will simply unretract themselves.

Sabine, I’m just a teen lost in life exploring the wonders of the universe. I never would’ve thought myself to watch any videos about science but here I am now.

Your videos bring me so much comfort and I wait for you to make a post everyday just to hear about what else you have to say. Thank you.

The New Scientist article would have a more accurate title if it was "Scientists entangle the probe qubit with an ancilla qubit and then this happens!" 😀

It literally like rewinding a video? It's not going backward in time, it's instant replay...

Objection! I spilled _instant_ coffee onto a particle accelerator one time and it was ready to drink 5 minutes ago.

Gregory Benford wrote a novel, "Timescape" based upon the concept of into the past. It was used as a signal from the future to warn the past of an impending disaster.

I was going to send a particle back in time-- but things got really busy at work last week and I was too busy to see it come in.

One does not simply ask a question on Twitter and expect answers. Only expect mental break downs.

"Unless you're a philosopher, then it means everything and nothing at the same time."

As someone who studied philosophy in grad school, I can confirm this statement.

This statement is also why I work in a woodshop now.

Well done. Very clear explanation of the issue without getting bogged down in T-symmetry and Entropy. Good analogy using a familiar subject, texting.

"Tonight's burrito isn't tomorrow's existential crisis." Well, unless it was too spicy... 😁

Came for the "Too good to be true", stayed for the comments.

"They'd be trading Bitcoin" 😄 The whole article in a single statement!

Thank you for keeping this one sane. We don't want Heisenberg to be more UNCERTAIN than necessary. It is a matter of PRINCIPLE.

"and then you block everyone who disagrees with you and hide their comments"

I was taking a drink Sabine!! AH MY NOSE
lmaooo

Thanks so much for creating and sharing this informative video. Great job. Keep it up.

My co - worker asked me where the socket wrench was. I said in the past and pointed to the toolbox where i had put it yesterday.

I'm not even convinced time is anything more than a conscious recognition of change. There is just simply now.

I've had the time traveler license for some time now. The reason why I don't travel back in time to fix the past is, that it requires more energy than creating a better future. Energy which I don't have anyway.
