Only Feasible Way To Travel To The Past
The only possible way you could ever travel to the past is if time was circular, in that it reaches a loop where it goes into the end/beginning, in that sense you could travel the speed of light to the point where you would loop time and get back to the year 1963, but for that you would have to go through the year 3000, 15000 and then 100 BC, etc
Even traveling the speed of light it would probably take months for you to loop time.
For instance, traveling 1 minute the speed of light would equal somewhere between 12 and 20 years into the future.
SO traveling for an hour you could be going about 1000 years ( 800-900 or so ) an hour.
Since the earth took around 5 billion years to make light and existed for around 12 billion years, let's say the time stands at around 20 billion years.
For sake of arguement let's say you can travel 1000 years per hour.
20,000,000,000 divided by 1000 would equal 20 Million Hours.
How much is 20 Million Hours?
833,333 days. How much years is that? 2,283
So okay, that would be pretty silly, but some scientists have argued you can go faster than the speed of light, and maybe that's true.
