u cant travel in time for sure. because what is time? time doesnt have a speed, nothing

even if u go 100x the light speed, u will never go "faster" than the time. it may take a 100000th of a second, there will still time that will have passed

wich means u cant travel faster than time to go in future

now, how could u get back in time? its alrdy gone. things happenned. its impossible to get back. i really dont think time can be modeled in any ways because time isnt something. time is just time lol
