Einstein would've liked it.
I gave you a 5 in graphics, since my idea of a Relativity class involves cows accelerating into a blurr and other einsteinian nightmares... :)
The theoretical part was flawless, and well explained. That's why I gave you a 7 in style. What were your sources?
Again, a 6 in sound (I digged the track), since I like thinks flashy and bangy! WHAM!! KER-POW! SPLASH! Uhh... whatever. And some voice-acting.
Singularities detected in Violence, Interactivity and Humor quadrants. Putting an astronaut (near a black hole) being thinned into a spaghetti string can be funny AND educational!
Overall, a 7. And a big THANK YOU for the intelectual uplifting of most Noobgrounders :) Life ain't just Halo and Dead or Alive, you know?
