How the 6D folding is done for time travel ?

Some keywords to start from: Time potential, Time dilation and Time travel. No need to read them now.

Lets start from an experiment.

We need two instruments which can measure time elapse in nano-seconds; Atomic clocks. This experiment has been done several times. My favorite is Gravitational time dilation. We need a tallest building as well.

To dos:

• Synch those clocks.
• Keep one of them on ground floor and another on top floor.
• Let them be there for some x time.
• Get them together after x time.
• Take readings.

Clocks were tested properly before such time critical experiments. It has been observed that the elapsed time on both clocks were different.

The difference in time ?? what does it mean?
It means that while experiment, the clock A was at different time potential and B was at different time potential w.r.t. to each other.

Time potential: It has been observed that at different distances from a massive object having great gravitational field can change the rate of flow of time. Well its no where written or proved as this name.

It means they both traveled forward in time differently. See we travel forward in time @ 1sec/sec. The references are immaterial unless a travel is done or two different time potentials are being taken in account as reference comparison. If two ppl are at different distances from the center of a massive ( object having greate gravitational field ) planet like earth, both ppl will observe 1sec/sec time flow only w.r.t themselves only. But
Well if someone does time travel in lab condition. How its known? If one is not from other's time. The time difference could be of a nano second to an infinity. Use clocks !
