young people object to older folks interfering in their lives, imagine the havoc if younger people could interfere with the past lives of their grandparents, or reach forward in time to fix outcomes? http://www.sciforums.com/threads/alma-sees-old-galaxies-before-they-merged-two-ways-to-look-back-into-the-past.160341/page-39
proposition on this linked topic:
The past does not exist anymore. Only fossils of it. We have past through the present, and can only see messages coming from the past, but the emitters have gone forward too, are gone. There is no machine to go back in time, but we are all going forward. While there is plenty of time in the future, we are not there yet.
Be happy that your adversaries, mother in law even , do not have power over the future. Enjoy the now, it is so short.
