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.

There are normaly three dimensions which are up-down, left-right, forward-back, and space-time making four.
Two dimensional time wants to add another dimensional plane into the mix.
In my opinion physicist are always trying to add dimensions that they can never prove exist to make the math work.
Your question is vague so sorry if I’m not giving the answer you’re looking for. Posting the article may help.
The current mainstream model of the universe describes it as having one time dimension and three spatial dimensions. However you can come up with models that have any number of dimensions, for instance F Theory describes it as 12D universe with two time dimensions (with kind of an asterisk but that’s beyond the point). These are very mathematical theories and one consequence of whatever set of equations they’re using is that you have to change the amount of dimensions they’re operating on to have them continue to describe how things move in the real world.
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.
