I just read an article saying that time may be disappearing. This hypothesis is based on string theory, and according to a series of papers published by Jose Senovilla and Mike Mars, our Lorentzian brane signature (with 3 space and 1 time dimension) may be turning into a Euclidean one (with 4 space dimensions), which means that time is slowly disappearing.
Now, all this sounds bizzare to anyone with a rational brain, but say I were a scientist and I wanted to test this hypothesis i.e. time is slowly disappearing, which experiments should I carry out or what types of data can I collect to confirm it ? How can I definitively prove or disprove this hypothesis ?
And please, give me some serious answers. No "just look at your watch" or "just build a time machine" type comments. I'm really curious about this, and I admit that I can't even understand 1 % of the theory behind it, but I still want to know what we, as humans, can do to prove such a hypothesis.
One of Mars' papers says that light cones will stop existing if we only had 4 space dimensions. Would the narrowing of light cones prove that time is slowly disappearing ?
Looking forward to your answers. The more, the better.
