i think Energy was the reaction of some other action that DIDN'T require energy...

an energy-less cause resulted in energy...

the question then becomes what could possibly be so awesomely powerful that it could create such a reaction WITHOUT energy?

Scientists think that our Universe may just be one "cell", or membrane amongst an infinite number of membranes, and they think that when those branes collide, they cause this huge explosion of energy (big bang), thus resulting in the observable world we see today.

I have a lot to add on your sight/sound/brain interpretations, b/c I LOVE thinking about that stuff, but I have to go... but basically, yea our senses are amazing and can allow us to experience 5 different stimuli of our world... but sometimes i feel like we are LIMITED to only those 5 senses... i always think that there are other things capable of being observed and experienced, we just don't have the SENSES to sense them.

it all has to do with our evolution... the senses became activated as they were needed... feelers and antenae started to grow at the front of our ancient, ancient organisms, and ultimately became eyes.

AH!!
