I've tried to simplify this down so it's easier to understand. I've been reading up on the paradox of Schrodinger's Cat.
It involves Quantum Mechanics which is a branch of physics dealing with physical phenomena at microscopic scales, where the action is on the order of the Planck constant.
I'll put it in spoilers so you don't have to read it if you don't want. It's pretty interesting but confusing
This is where the saying 'Curiosity killed the cat' came from, as far as I know

You put a cat in a bunker with poisonous gas that has a 50% chance that it will leak and kill the cat, and a 50% chance that it wont leak and kill the cat in the next 30 seconds. So, at that moment in time that cat is in a super position where it is both dead, and alive. The cat is in the super position until you open up the bunker. Curiosity killed the cat.
This leads onto the theory that there may be two realities where someone is observing us, and we are similar to Schrodinger's Cat. Who's observing us to cause natures to collapse towards one reality.
Or, are they happening in parallel where each event happens in a parallel universe?

I may be thick here but can you answer the following??
Why is the cat in a super position in the bunker when he has a 50:50 chance of living or dying?
Surely he cant be both dead and alive, is he not alive unless the gas leaks?
And why does his super position end when you open up the bunker? Surely his situation improves?
Must admit I am not very good on these kind of discussions.

NSPCA would love to hear about this I'm sure..

He is in the super position because you don't know weather he is dead or alive. So he in fact both dead and alive at the same time.
Until that box is open you don't know what state the cat is in there. How can you tell he is dead or alive?
Confusing huh?

You dont know but he does - or is that the point?
I have had similar discussions with a work colleague who has a degree in philosophy before. He will say something like 'We are working on the ground floor in this building at the moment. How do you know the first floor is actually there?' - or something like that!!

It's basically a Paradox
That thing has a 50% chance of it being there and a 50% chance of it not being there. You don't know 100% that it is there until you have checked for yourself.
There's also the Special Theory of Relativity that Einstein worked on with his famous E=mc2 theory. Which is incomplete as that is only for stationary objects.
It states that it is impossible to faster than the speed of light without infinite energy. Infinite energy is needed to break the speed of light. But this law doesn't say anything about particles breaking the speed of light.
Recently in the particle collider in Switzerland observed Neutrinos 'going faster than the speed of light'. This will turn laws of physics into nothing basically if this is true.
This could also prove that Time Travel is possible as you are needed to go faster than the speed of light to be able to time travel.
Interesting stuff?

According to Einstein's theory of special relativity, published in 1905, nothing can exceed the speed of light. That speed, explained Einstein, is a fundamental constant of nature: It appears the same to all observers anywhere in space. The same theory says that objects gain mass as they speed up, and that speeding up requires energy. The more mass, the more energy is required. By the time an object reached the speed of light, Einstein calculated, its mass would be infinite, and so would the amount of energy required to increase its speed. To go beyond the infinite is impossible. One hundred years of testing have only reinforced what Einstein wrote, said Donald Schneider, professor of astronomy and astrophysics at Penn State. "There is no experiment that has contradicted special relativity. We have accelerated sub-atomic particles to well over 99 per cent of the speed of light, but not equal to or exceeding the speed of light. "Theoretically, strange things happen when you exceed the speed of light," Schneider added. Time travel, for one thing, and a breakdown in cause and effect. Schneider uses an example of hitting a target with a gun that shoots bullets faster than the speed of light. "Some observers would see the bullet hit the target before they saw the shooter fire the gun," he said. "Since one of the guiding principles of relativity is that all physical laws are the same to all observers, this violation of causality would be a big problem."

I'll reply after xmas, stuff's a bit hectic
Remind me!

To be fair though, that is probably in the opposite direction to the bar when you think it might be your round!!

Well I wouldn't be daft enough to get the round when we are doubling up would I?

People wouldn't see the bullet hit the target before they saw it fired, the bullet would hit the target before it was seen to be fired (as you seeing the bullet is seeing light, and the bullet is travelling faster). It's more like if you paused time you could feel a bullet hole in the target but look like there was no hole because the light before the hole is made is still what would be travelling into the perceivers retina.
Though I may just be sounding a complete fool as I've never studied physics beyond GCSE :p Ahh well it's Christmas. Who said last orders?
As for Schrodingers cat, it neither is alive or dead, but a state of unknown. Like if you haven't checked a lottery ticket you've neither won nor lost

Although actually you have either won or lost!!
I didnt check mine on Saturday and won £47 for 4 numbers.

I can and have gone faster than the speed of light
no lies..
woosh see
use missed it im that fast!!
il do it again tomorow maybe.
