I had a dream last night that in a galaxy far, far away. there was a group of planets each in differant stages in years. how do we know that there maybe not another planet with other humans on but abit back or forward in time. e.g. electricity on there planet hasn't been invented. Or another planet has fount a cure for cancer and other mind boffing things that were just to thick to figure out. what if theres some way to travel millions of lightyears to deap galaxy and discover these planets. think about it mars jupitor and all them other named planets arn't just the only other planets. i really belive theres are millions of planets with life on them. and these so called aliens are just other people which are ahead in inventions and evelved more than us have created vehicles that can travel so fast and they've gone to search for other planets just as were so optimistic.

there must be people with my thoughts :P please comment on this intresting topic :D byee

theres a strong theory that when moses threatened, the egyption pharoe with natural calamities if he didnt let the iraelites go, there was a polution cloud above egypt, waiting for his answer, if he let them go the cloud would have dispursed out to sea.but he didnt let them go, so the cloud came down on egypt. so the pharoe could have turned back the tyde of disater. do we have the same choice

I once read that during the time of Moses and his mass exodus of the Jews, the miracles/plagues he performed were not of his or God's doing. That also being the case of their 40 year wander in the Sinai. I read that it was actually due to the fact that Venus was in propulsion from Jupiter and was sent hurtling past the Earth, causing these events, and that if it had tilted our axis, we wouldn't be here today...is this true?

Consider holding a large magnet. now move the magent closer to a small piece of iron. When you get closer, the magnet attracts the iron. This attraction moves the iron to the magnet. This movement produces WORK since Work = force x distance. This work expends energy. Does it mean that the magnet "looses" some of its energy? Will after so many tries, we will exhaust all the magnetic properties of the magnet?

This is just some thing that made me think.
