If time travel is possible, I want to go to the past. Not for changing the future. But I really want to know what happened in the past. Still there are some questionable matters that I can't believe. That ancient history is, in fact, confusing. I'm curious to know what happened to the kings who ruled in the past; What they did;and what technology was there at the time? It's really interesting. Looking at the ruins that remain today, it is clear that the most advanced technology existed in ancient times.But for some reason those technologies have become vanished. Still don't know the reason. So if I can travel time it will be a great journey to the past. But If I couldn't come back by a mistake ,what will happen?
