Physics tells us that time is relative and mathematically you could move backwards and forwards in time since you could substitute 't' by '-t' and all equations of Physics would be equally valid (including all the gravitational equations, the equations of quantum mechanics and thermodynamics). Then why does it appear to us that time moves forward, why do we age and why do we die?. (Einstein called this the most stubborn illusion).

You have 3 coins, one has heads on both sides, one has tails on both sides, and one is a normal coin. You put them in a bag and shake it. You draw one without looking and look at it in your hand. you see heads. AT THIS POINT what is the probability that you drew the double headed coin?
there are 2 possible answers for this:
1: 50% as you have 2 possible coins one is the double sided one the other has tails on the back, therefore 50%.
or
2. 2/3 as since it's heads you had a higher probability of it being the double headed one because it has 2 possible ways to draw heads.

I maintain that it's 50% as you had no possible way of knowing you were going to draw heads until you drew it therefore it was tottally random until you looked at it at which point there is 2 possible answers therefore 50%. It would not be 2/3 unless you TRIED TO DRAW HEADS, which is a complicated logical thought. what do you think?

Ignore All '+' signs while solving. for better visualisation redraw the structure in a paper without the '+' signs. Here '+' are given to maintain the structure as it does not take spaces and the structure was not accurate.

Ok I just read the question about whether or not Sicily is an island or a part of Italy, now I am getting really technical here but Sicily is 100% owned by Italy. Not listed as a seperate country anywhere, even though I know it basically takes care of its own. I know that people from Italy say they are Italian and people from Sicily say they are sicillian. This is kinda to prove someone wrong here a girl I know was trying to say that that were two totally different countries all together. Someone set the record straight for me thankx

According to Einstien's theory it is said that space is itself curve so it is impossible to go out of the space. So can't we really go out of it . Universe is to be said extending everytime so where is the space for it to extend?
