Oh, honey. Clean your screen, it's gotten all reflective again.

Yes, and it's primarily gathered around Mondays.

I read the article, i think I understand what they did (sort of)... But can someone eli5 what they did but especially what the hypothesis is that happens to explain negative time

Yeah yeah. I understand too but like someone should explain it to everyone else so they understand..

This comment is hilarious

Photon comes out before it goes in.

I don't really understand it either, but keep in mind this is happening at nearly lightspeed, so it's not like the detector is lighting up right before they press the button to emit the photon.

Which makes me wonder, what happens if you combine this with "slow light" effects?

"You destroyed the fabric of spacetime"

so there is anti-space, or negative space.

But only after a decision was made by a person to create the photon? Because otherwise that would be pretty spooky.

So this doesn't sound like we would be able to send people through. But information could potentially be sent back in time.

And that is a huge can of worms. We'd potentially get an actual answer on how time paradoxes get resolved.

Load up the machine with the latest lottery numbers, send the info as far back as the machine can do, and see what happens.

I'm guessing the current amount of negative timeisn't enough. But I'm sure with enough experiments & understanding it could be pushed out a bit. Worst case it'd have to be an automated process with a computer doing the gambling.

We need to create the Robux cube ASAP

Wtf are you on about. Read the article.

I did read the article. It says the photon comes out before it goes in, and photons can and are often used to transmit information.

So extend the principle further and you have time traveling transmissions to your past self.

You clearly did not read the article because that's not what is said.

Chill a bit Neil deGrasse Tyson.

Yeah, it's only once the photons in front of it could already have gotten there, so it's like photons from the tail end of the pulse are catching up to the front as it emerges, even though they haven't even entered the cloud yet.

What one finds is that the photon actually arrives far earlier than that. In fact, it arrives so early it appears to have spent a negative amount of time inside the cloud – to exit, on average, before it enters.

Yeah that's pretty weird but nobody could ever notice unless they knew what to look for. Now, if you had light beams coming out of there like 3 seconds before pressing the buttons, that would be scary weird.

I know - I experience it when I wake at 3AM and can’t get back to sleep.
