Niel inspires me so much. It is such a good feeling to have questions that I've wanted the answer to since I was very young answered, without any stupid huge words that don't really mean anything, or complicated incomplete explanations or simply an "Well there are several theories about that." I wish that I was as reflective as Neil, so that I could answer these questions to myself.

Neil is pretty much one of my favourite people ever. I could listen to him talk about space stuff for hours. :)

Wow. Seriously Neil deGrasse Tyson again fails to disappoint. What an astounding job condensing complex ideas into a simpler form, so the common man could understand. One can see he is truly a force for human progression, for those who are inspired by his words, strive to obtain either the same, or a greater level of understanding he has displayed. There is a freedom given from this knowledge, a freedom to understand the beauty of the Universe, and a desire to overcome the "impossible".

I think that's my favorite quote - "Get over it, eight" xD

[Alee]

Every time I listen to Neil deGrasse Tyson I truly learn something new. The concept of a hyperverse is something I've never come across, now I'm gonna go and think about this until my mind has been fully intercoursed by this concept.
