18 moves I could see, 17 moves... Pffffttttt

Surely one can do anything with his dedication and hardwork.

In india a small 7 yrs old unrated child have defeated a GM. Superb na. And now he is rated 2234 at just 9 yrs.

They were likely better than 1300 at unrated.

Possible? yes.

the typical 1300 could not beat a typical gm though. Great question. I wonder things like that myself. :)

In theory, there is the possibility that the 2700 will play pathetically enough to be beaten by the 1300, but the real likelyhood is not one representable by numbers. You can play as many games as you want against a 2700, but the gap in tactics, positional play, combinational play, and opening/endgame knowledge is close to insurmountable and the 2700 is pretty much guaranteed to win every game.

Only in mathematical terms. In practical chess terms there is no difference.

Your estimates are a bit off. Our galaxy has somewhere between 200 billion and 400 billion stars, and the likely estimate of galaxies in the observable universe is close to the same number. The universe is around 13.75 billion years old, with an observable sphere diameter of close to 100 billion light years (expansion places galaxies much further away than we observe them).

Not to mention, our universe might be just on of a countless number of em.

possible i am rated 389 JCL but i defeated a 800~ player in an OTB tournament today (not to mention that my rating is now probably above 400

Ultimately though, if a 1300 player beats a 2700 player, has he really 'beaten' him? Really it would just be probability and incredible luck, the 1300 player certainly wouldn't appreciate the actual depth of the moves he made by chance.

Perhaps that 'multiverse' is only one of a countless number of 'multiverses'

Might be the case. :)

And perhaps that... oh never mind

Could be a hacker just like you, making that same statement in another universe far FAR away.

By your hypothesis, in a countless number of far away universes.

If there are other universes, would they be theoretically accessible through the conventional dimensions of X Y Z and T? Or would they exist on some mysterious 'other plane'?

Weird stuff - I don't know a lot about physics but it's interesting and sort of makes your head explode trying to think about it.

Weird is right. It's not my hypothesis, and I know little about it, but other universes would never be accessible to us.

NO.
