You can make the past effect the future as well as have the future effect the past. What you are going to do with this knowledge? You will force your brain to do new things in new ways by being aware that you can do them.

Einstein saw that the universe must allow for certain processes to run backwards to keep the balance. Its not time that will run backwards but certain processes of information that can go backwards.

These are some of the empirical areas of exploration that I think help explain how we can know more than we need to know as well as things that normally seem impossible to know.

Remember those random number generators? The only thing they can do out of the ordinary is to become non random or become synchronized with other generators. They do and will become synchronized in harmony with an event of millions of people looking at or focused on the same "think".

A living system changing a machine by thinking? Yep. We are all in the same quantum universe together, machines and people alike. Yet we are not mechanical devices. Nor are we living in a clock work universe. We are living in a non material universe of waves of possibilites, waves of potentials, waves of optional outcomes.

Spooky? Slippery? Well it is what what it is in this field of interconnectedness. Even to the point of being interconnected with other conscious life forms throughout the universe at large and not just a lonely mistake of a far flung solar system.

Change your central paradigm toward a larger reality, and you have changed everything in your life. The effects are real. Your foreknowledge will bloom, your attitude will soothe both mind and body. It will even effect the world view as it grows.
The world is begrudgingly accepting an unsuccessful paradigm. Yet one thought at a time it is changing. Of the 4 billion bits of information processed by the brain in a second we are only aware of 2000. Take that 2000 and focus it in a more constructive paradigm and solid realities will result. Embracing unconventional knowledge is fairly easy. It sort of feels happy and pleasurable combined with a heightened sense of wonder.

So far I have only noticed changing small packets of the past from the perspective of the future. So far I have only had foreknowldge of large shared events in as much as 5 years in advance.

Endorsing one reality over another will give a tiny push for a contray outcome to collapse in VERY small ways. Even a constant miniscule push adds up to push very large events to slow or stop and in a quantum leap a new potential becomes more likely.
