ps3

ive been told that virtual particle's are allowed to travel faster than light due to uncertainity principle. here is a link where i got my info. http://math.ucr.edu/home/baez/physics/Quantum/virtual_particles.html

what does this all mean? i was told by a friend that causality is violated but since we can't see it happening it cannot affect us.is this true?

so it can last infinitly?

what is the longest time a virtual particle can last?

i have some link's where it's said they DO violate causality. http://math.ucr.edu/home/baez/physics/Quantum/virtual_particles.html http://www.ucolick.org/~mountain/AAA/030718.html

can virtual particle go faster than the speed of light?

so this mean's cause and effect is safe from being violated?

i read that virtual particle's CAN travel faster than light,because of the uncertainty principle?

so what is really going back in time? this is what confuses me with anti particle and particle time travel,back in time sort of thing.

why can they violate causality?

what do virtual particle's violate?

do they violate causality since they travel faster than light and violate conservation?

what confussed me is if there is any time travel going on in reality?

i remeber someone telling that a particle is an anti particle moving backwards in time and time travel to the past was all mixed in with feynman's diagram and t-symmetry.

so what is it that in reality goes back in time?

this is what really confuses me when im told anti matter is matter going back in time,then im told that they don't expierance retrocausality.what im asking is do anti particles or particles in reality travel back in time?

can i just say the interactions of all micro particles?

im sorry,what i wanted to actully ask is if they in reality "go back in time".

what is a simple difenition of quantum mechanics?

or go back in time?
