A couple of months ago I got really obsessed about time travel following Eistien's theory's on it and I found that time travel was possible both ways just very hard to go back in time but while lookin at these theory's I found that it's possible to make the body respire backwards at speeds way faster then the speed of light if done in a gravitational enviroment although it is hard to control it can make anything do a course backwards.

This blue crystaline solid ---> dissolve in water and add dilute nitric acid and barium nitrate solution ---> a white precipitate "M".
This blue crystaline solid ---> dissolve in water & warm with NaOH solution ---> a gas "N", that turns red litmus blue.
This blue crystaline solid ---> dissolve in water & warm with NaOH solution ---> a blue precipitate, "O".
This blue precipitate, "O" is mixed with excess dilute sulphuric acid to give a blue aqueous solution that evaporates slowly to give a blue crystals, "P".

Q: What is the identity of substance "M", "N", "O" & "P"?

Solve this question correct with detailed workings and earn points!!! :)

It's a kind of rare point of view in which the energy it's always expanding and that it seems to me that gravity it's been seen as a process of expanding energy of the matter instead of an attracting force. I don't really understand it. Can somebody explain it briefly to me?
