The simple subjective difference between past and future is that we believe we have knowledge of the past and (if I am not overgeneralising attitudes) that the past is perpetually rigidly fixed, while we have no definite knowledge of the future and can only predict it to a limited, imprecise extent.
Both views are rather imprecise. If you exchange the words "go to" with "come from" and the word "past" with "future", you can make structurally similar statements to the ones made in the OP.
It's really no big deal. I don't know about all of you, but I go into the future all the time.
Since I was born I have been traveling through time for 74 years and have been meeting new people, places and new inventions.
There is one problem I have, how do I go back in time. I can't get back to the past.
The best example is when I get into an elevator and the door shuts. A little while later that elevator takes all my atoms into the future and deposited them at another location in the future. Then I try to get back into the past by getting back into that elevator and bingo I go further into the future.
I seems only to work one way. The same happens to me on a Jet plane. It only takes me into the future.
There will come a time when I will be able stop from traveling into the future.
That's right after the Grim Reapers knocks on my door. Click on the link.
