Just read a headline saying scientists have created two dimensional time, what is this? What practical applications will it have?
The article was locked behind a paywall. I’m not sure if this sub allows links otherwise I’d link it.

In order to make it to an event in our universe, you need four numbers: three to define where our event is taking place in space and one to say when it’s occurring in time.
So we might say:
>The party is at the corner of 1st street and A avenue, on the 3rd floor [a location in space with three coordinates] at 2 PM on Thursday [a location in time]
Two-dimensional time would require two independent coordinates to uniquely define a point in time, so our event would have to be like:
>the event will occur at the intersection of 2 PM on Thursday in time 1 and 5 PM on Friday in time 2.
This would lead to a radically different universe and is as difficult to visualize as 4d space is, but we can describe it mathematically.

Do you have the article? 2d time isn’t how our universe works, so they haven’t actually created this and this sounds like a sensationalized headline.
