To achieve 'time-travel' we must first eliminate "Time" from
descriptions of the world. We can do that now: 'before' and 'after' are
merely abbreviations for spatial events. So it is grammatically
incorrect to say that we 'travel' or 'go' to 'past' or 'future' events.
We 'achieve' spatial events, that's all.
Two examples:
If we want to 'go' to a 'time before' such as the Fire of London, then
we can reword it to say that we can 'achieve the Fire of London'. We
would do this by building timber houses and setting them alight. If we
insist on having the date 1666, then we would have to change other
things as well.
An easier 'time before' to achieve is the start of the universe. This is
quickly achieved, at least for a photon, by 'travelling' at the speed of
light. Like the Fire of London, this event is always spatially and
potentially 'with' us. |

So then, in order to "witness" the Fire of London, one must
ride on a photon? Sounds insane from a scientific viewpoint,
but it has poetic brio to spare!

Given this post, your reaal problem is how you can now "achieve"
philosophical credibility!

Are you saying that time is man made, and if we do away with watches,
calendars, sundials and all the rest, we will no longer be limited by time?
