TIMETRAVEL
Timetravel is possible with a pair of PHT's.
You must choose the right foto fotonic conversion factor.
Then you must choose the time you want to go to and the place in that time you want to go to.
The place can be chosen by filling out the X-, Y- and Z- coordinates.
For the right time will be chosen by the T-coordinates (time).
Put the pair of PHT's on your head and wait until the flash of light appears.
