What's behind time travel?

As I walked in this wasteland, I noticed a village of some chaotic tribes, we entered the tribes city, I said to myself "Might as well, take a break," . This bethemoth place is barely searchable by normal human, well, my crew and I manage to create a codex of the unknown, well, we will call it "Quantum's mechanic transportation", might be too long, maybe "Unveiled portal?" . I said to the other crew member, "Are you sure this is the Quantum Paradox Land, because how come there are civilization, is such unquantum mechanical realm? " , I then said to myself "Maybe it was something else?" . They respond with, "Might be a punishment realm for those who time travel? Because their tech is way advanced," I said to myself after that unusual respond " How come they read my thought?".... . I then said to them "We might even see tacyhon, if you are sure of this land, is truly the Quantum Paradox Land, or even the mysteries of the white ..", Then I was intervene by one of our crew member, "I am not so sure...it might be a trap, by the ...," I replied "Who exactly?...Might be a punishment" We were intervene by thought of what truly happen, I pull out one of my equation, Time rebound..."If you suggest, we are time travelling, then, how fast have we gone before" I said, then wrote it "Time rebound or Time dilation, or Time speeding equals to our speed over speed of light, well, we only need our speed" I said again, then one of my crew member said "I wasn't reading our speed before, neither had the others,", It was stressful, as the land suddenly became eerie, sounds were like creaking....
