So you’re saying time is always fixed and the past can not be altered.

Yes.

Travelling backwards in time is impossible due to causality.

Travelling forwards in time relative to now is possible due to time dilation from increased speed + distance from Earth.

Or you could just freeze yourself in the snow and wake up in 2546 and become the time child.

The past is the present waiting to become the future. All three of these exist simultaneously. The human mind is only capable of perceiving the present.

You could probably alter small things, but there is probably a hard limit of what can and can't be done. A better use of the energy would be to save the people who got murdered at the death camps. There's a really cool episode from the 90s outer limits where a time traveler helps a lawyer try and prosecute a former German death camp guard.
