Biggest problem is the Grandfather Paradox

What is the grandfather paradox?

Well, the grandfather paradox is an attempt to disprove time travel by claiming that if time travel were possible you would be able to go back and kill your grandfather, therefore you were never born so how did you go back and kill him.

This chicken and the egg scenario is all wrong. Let me explain. Back in the 70's I talked about creating a Cash vending machine. You put in a credit card and it gives you Cash. The machine would charge you a quarter for the transaction.

A debunker stated something like "Nobody is stupid enough to pay the bank to get their own own money out!" He stated that it was foolish to think that a bank would replace a $13,000 a year teller with a $50,000 machine, that nobody needed cash at 3AM, but the debunker came up with his magnum opus, a scenario that prove that my cash vending maching, or ATM was impossible.

Imagine that you put one million in the bank, you ask the bank for ten credit cards. One for each member of your "family". You and your friends go to ten seperate cash vending machines and withdraw a million dollars simultaneously. You now have ten million dollars.

In theory this seems possible, but in reality it is not.

The grandfather paradox cannot occur because if you did go to your original timeline, the timeline splits into two. On one line you kill gramps, on the other you do not.

According to Al Bielek if you split the line enough times then it collapses or evaporates and blinks out of existence. The universe does not have an infinite amount of energy.

This is why you should not go back to change events!
