I think it’s easier to go foward in time than backwards. I think this because of an experience I had. I experienced the event before it happened. I was very shakened but who wouldn’t be shaken by a car accident?
Then, a week later, the actual event happened...i mean in my present time.
I knew immediately that this was the event, what was going to happen, how it was going to happen and even what the injuries were. It gave me an opportunity to correct my own responses as well as experiment with a few things. For example, in my foreview, I asked the police officer for a cifarette and he gave me 4 of them. So I tested it and asked the officer for a cigarette and low and behold..he gave me 4! I was sitting in the back seat of a police car in the preview and in the present view. I knew the head injury sustained by my husband was minor and that the police would give him a ride home from the hospital...so I asked the police to take me home. They did and they wouldn’t take me to the hospital which I already knew.
The event was in the future but changing the past occurred when the past became the future..and the present.
And no, it wasn’t dejavu. Drhavu is the “feeling” that we’ve been there before, but there are no actual memories to support the feeling.
So yes, I do believe that time travel is not only possible, but can occur naturally. And that you can change the past in the present because the present becomes the past very quickly! If you know in advance what happens, the outcomes, you can change those things only to a degree. You can only change what YOU do or what you feel.
In my preview, I reacted hysterically so when the present event happened, I was at peace and remained composed. I already knew the outcome.
Im not a mathematician but could my statement above be translated into an equation? I’m sure it could be..and the statement provides the answer. Others have experienced it as well.
Here’s a link to a a PDF that contains short stories by the famous SciFi writer The late Issac Asimov.
One of the stories in it, the first one, is called ‘The Dead Past’.
It somewhat relates to your situation............ENJOY!....
