Not implying any innuendo.
It's the offseason, back at work, bored pooless and craving something mentally stimulating. Feel free to drop anything scientific, philosophical, metaphysical, or just plain thought provoking or brain busting. Also try to remain objective.
To start, I was re-watching Stephen Hawkings' latest Into the Universe series again last week, particularly an episode on black holes and creation. He stated that in a black hole time does not exist, therefore there was no time before the singularity. This is something hard to comprehend. Probably as hard as teaching Sagan's Flat-landers about 'up.' That is until you start breaking down the principles of black holes such as dimensional warping and such. Only this way can our simple brains nut it out.
After that I tried to begin a process of imagining a tesseract. And I can't for the life of me confidently say I can imagine it, and I don't mean just understanding it. We are tuned to perceive a limited amount of dimensions and sensations. When a pit viper sees a thermal image of its prey we imagine some sort of military hardware of a blue image and red targets. But this is using our own visible light spectrum to comprehend a frequency see we cannot see. I guess this brings in the epistemological question...
K, go
