So what does this all mean? Is a time machine just around the corner?
Sadly, no. Our experiment is fully explained by standard physics.
But it does show that negative dwell time is not an artefact. However paradoxical it may seem, it has a directly measurable effect on the atomic cloud that the photon traverses. And it reminds us that there are still lands to discover on the odyssey that is quantum research.
I was awaiting on an explanation... now I'm just left wondering.
That is how %100 of physics articles with cool names feel like, you usually end up with something like "we measured a slightly different voltage which in this context is a signal for the existence of parallel universes"
Negative time as experienced by most people at the DMV.

So ... a proton exits this 'atomic cloud' before it enters?
Are we potentially getting close to detecting if a tackyon exists?
Seems pretty standard model still, more interesting behavior hiding in the indeterminance principle. Still, negative time hints at negative energy which could certainly change the game.
negative time hints at negative energy
Energy = mass, and negative mass would have some really bonkers paradoxical behavior...
Including the aforementioned time travel via stabilization of wormholes ala Morris–Thorne...
Some ad?
It's a gif from the movie Tenet, which is about negative time.
No, it's a video of the moment the two scientist measured negative time....
It's from the Movie TENET
I think it's the movie Tenet
Oh no, it’s the plot from Outer Wilds! Don’t go breaking spacetime.
Well, part of the plot anyways. Im pretty sure we save spacetime from the big cold dark in the end. Or something.
Measured it with what?
Here is the paper from 1993 when this was originally tested.

Haven't many people experienced that? It's called scrolling on social media, right?
I think that's time dilation, when your 10 minutes on the phone was actually an hour.
