I wonder how to apply the uncertinty principle to the big bang?

I found a few mechanical relativistic simulators: http://www.adamauton.com/warp/links.html My be I/we could change one of them ...? but in what way?

Could it be that there is no simulator that could simulate Relativistic phenomena?

I am looking for a simulation tool that could simulate this type of phenomena Just for grasping the principle a little better Could you recommend one? Thank you. David.

OK, Purcell shows my mistakes one by one without shame :-) 1) There is no UP force caused by the moving charge of the train. The magnetic field lines are up , the current flow is in the same plan as the force perpendicular to the UP pointing magnetic filed lines. 2) A wire is...

My problem is with visualizing this phenomenon. If we will think of a moving train that carries electrically charged material - we get moving charge. From the mathematic I can see the cross product being transverse to the moving direction. But I can not think of any "reason" (if a "reason"...

I know that electric and magnetic fields are the same phenomena just from a different perspective. I also know that this is related to the relativistic speed of the electrons flowing in the wires. I am unable to grasp the picture - how does it happen? Do you have an explanation? Thank...
