I see when you go back in time, not all paradoxes disappear, they just become invisible.
Think of time travel into the future or into the past, is like a movie film on a projector projecting
information at a point in time, which means you have history in the future and in the past and
you will see the here and now.
Now if you want to see the paradox you need to move a few frames ahead or few frames
backwards, to the point the paradox will start slowly appearing, then you can experience the
paradox in question as it really happened in time.
