Are there sub-atomic particles than can zoom backwards and forwards in time ?

Probably. That is to say if we can imagine it we could probably find it. Or make it so. We are a powerful creature mankind. The things we can do are amazing. So there is a probability to it as well as the ability to discovering it if it exists.

Elementary particles have been shown to travel through time.
I think the experiments to prove this were done in Harvard in the last 10 years.
The experiment is based on a individuals awareness of being observed and recording the activity of their central nervous system. If they are observed After (via video) the activity is recorded (and the results have not yet been observed), the results show their CNS behaving as if they were observed during the recording.

I know this answer is vague, but look into it. They’ve proven that information can travel backwards through time, related to the Zero-point feild.

Beneath Plank scale,,time space have a whole new meaning,,

if sub atomic particles presently ‘exist’ is dependent on if they ‘prefer’ to or not, they certainly do not have ‘existing in a linear timeframe’ as a property.

Now as responsible for causative failure one could guess that if enough of them teamed up together there might just be enough of them preferring not to exist in the same pattern to for example make a small item completely disappear, this could ‘throw an unspanner in the works’ to coin a phrase given that no one checks for ‘unspanners in the works’ this would be overlooked and could cause cataclysmic failure similar to that of our old pal Murphy.

Time travels in one direction and can’t be changed.
The future doesn’t exist yet but a subatomic particle going back ward in time would put the present in the future.
