No offence but do you know how you sound like?
A very logical argument . Wow.
No offence, but you don't seem to be of mathematical background. Intersection is in no way relates to travel as you say it. By intersection it it is implied that you can't exist on two of them together.Let me break it down for you.
Consider a point of intersection of two lines, this point(call it A) exists on both lines(say m1 and m2) as in it satisfies both of their equations. Now let the two lines be parallel. There won't exist any real point which would lie simultaneously on both lines. Now change the lines to universes and the point to an individual.
Fermi paradox is not even a paradox per se....
(from wiki)
It is based on lack of "evidence" rather than a physical impossibility...I'm not even sure you understood it.
So what is your argument?
You reject the existence of Multiverse, because you feel it is a waste of your time?
I tried to hint you to do that by skipping a reply of yours, but it seems you are too hung up on it.
What i said was multi verse theory is stupid and controversial...
It is controversial ... that wont change because you want it to....
I think you dont understand what i implied.. But you seem to be very good in physics..???!!!
Look even by your argument If the Multiple parallel verses exist, then there is no use to us or the matter of debate (time travel) is there..
1. You travel to other univ- meaning you are leaving the present universe!!!! So this universe is not going to change now is it???? So what your actions can bring is not gonna affect the universe you left does it... here the grand father still Abused you....!!!!! now that is not going to change does it???
2. In the other univs, even if you stopped the Grand father from abusing you, it is not you who is saved is it???? Now if you cant understand something as simple this ... then ok
As you may have it.... You won the debate
But before that... How does time travel equal multiverse travel...???? this time i am an idiot as i cant undertstand
this as time travel is the matter involved in the paradox....
