Spoiler: we will never invent time machines :( if we had then we would have all ready gone back into our present and told us about it :(

yeh probly not but u can sorta use ur mind as a time machine

Except if:

  1. Laws are put into place to prevent travelling before a certain time.

  2. Nearly nobody knows about it.

  3. Time machines can only advance forwards in time.

    …and probably a lot more.
