Sunday Night Blog

Brushing my teeth through the years, I have always been painfully conscious of the fact of my self-awareness. As you have probably heard before, tests suggest that dolphins are also self-aware:
To test for dolphin self-awareness, Diana Reiss of Columbia University and Lori Marino of Emory University exposed two bottlenose dolphins to reflective surfaces after marking the dolphins with black ink, applying a water-filled marker (sham-marking) or not marking them at all. The team predicted that if the dolphins which had prior experience with mirrors recognized their reflections, they would not show social responses; they would spend more time in front of the mirror when marked; and they would make their way over to the mirror more quickly to inspect themselves when marked or sham-marked. The experiments bore out all three predictions in both dolphin subjects. Moreover, the animals even selected the best reflective surface available to view their markings.

Also, our galaxy, the Milky Way, is scheduled to crash into another galaxy, the Andromeda galaxy, in about three billion years. Please make a note of it.

The Local Group of galaxies -- the group of galaxies that includes our galaxy, the Milky Way, and the Andromeda Galaxy, which we are going to crash into.

Eleven o'clock at night on a Sunday is a very sad time. Compared to other days, the darkness on Sundays is darker.
