Time is Spherical

I think Stephen Hawking's illustration of a ball that you are winding string around is the best so far.

If you observe carefully, the string (where it intersects with the ball as you wind it) basically never hits exactly the same way at the same place any time you wind the string.

So, NOW, is the point where the string is touching the sphere right now. and that now keeps changing.

So, when you start another timeline by changing something by going back and redoing something, it basically causes some things to change in a big way or a small way like a Wave through all time after that.

So, it could be a big change or a small change.

So, imagine the 2nd time line  when Trump got elected how this changed everything.

Now imagine if Hillary had got elected instead.

Well this did happen on the 3rd timeline but not the 2nd.

So, imagine how different everything is on the 3rd timeline than on the 2nd.

More people are alive by the millions on Hillary's timeline but then by 2080 or 2090 the human race might go extinct from over population because of the millions more alive having babies and grand babies which could equal at least 1 billion people more alive by 2080 than now.

More people are dead and maimed on the Trump timeline which prevents human extinction this century through overpopulation. However, it doesn't stop wars or famines or disagreements between nations either. So, the danger isn't human extinction by overpopulation like on Hillary's 3rd timeline it is the danger of wars and confusion and millions and millions more dying of weather related causes because Global Warming isn't being addressed enough to stop that instead.

So, through Trump the human race is less likely to be extinct but also much less likely to be happy or polite either by 2100. However, wars and disagreements might also increase under Trump in addition to millions and millions more dying all the time from bad Hurricanes and Typhoons and droughts and tornadoes and you name it and floods worldwide.

So, time is spherical whether it is Trump's 2nd timeline or Hillary's 3rd timeline.

So, hopefully both timelines will find a way to survive the 21st century because that will give the human race more options than the 1st timeline where you are I are all dead (or wish we were) starting on 9-11 when 5 billion people died that day and most of the rest died the next year or so by 2002.
