  1. I love your choice of music, it makes me happy every time. I wish there was a downloadable DRM-free archive of all music that you use. Not many songs are available from the lists you publish. I mean, I know that some of it is custom-made etc, I understand why it's not public, but I just wish it was available…

  2. If Earth is the only place in the universe with life, we could be the most significant insignificant speck in the universe.

  3. This could be just because they see at a certain angle. If you look at Vesta top-down at the pole, it would look spherical. But its not.
