Subject: Do positron trails show up in cloud chamber photos?

Do physicists have photos or sensor data showing the spiral motion of 
positrons when a electron-positron pair are created? It seems that if 
positrons are electrons going backwards in time then if the recording 
equipment is moving from the present into the future it should not be 
able to record the trail of a positron that moves from the present 
into the past. Either in the photo of a pair production or in the 
photo of a pair annihilation, the positron trial should be missing. If 
it shows up in both then is it possible that time is not a 4th 
dimension but shares the same 3 dimensions as space? Is it possible 
that particles spinning and orbiting in 3D space are also moving in 3D 
time. Is it possible that it is just our mind that creates the concept 
of past and future when in fact motion in any direction in 3D space 
causes motion in any direction in 3D time with both time and space 
sharing the same 3 dimension? I know this means maybe minkowski didn't 
get it just right. If "s" is the direction light travels in space 
starting at coordinates 0,0,0 then:
s^2 = x^2 + y^2 + z^2
c = s*t
t = s/c
t^2 = (x^2 + y^2 + z^2)/c^2
t^2 = x^2/c^2 + y^2/c^2 + z^2/c^2
t^2 = (t of x)^2 + (t of y)^2 + (t of z)^2
