Scientists think our solar system could have hundreds of dwarf planets. So far only five are officially recognized. All of the following are dwarf planets, except for one. Which one is it? Pluto Ceres, Eris, Mercury, Haumea, Makemake. Meera! You were first on the buzzer. Tell me, which...
It's difficult to envision how dwarf planets such as Sedna and 2012 VP133 could receive ultra-red material from the Kuiper Belt because they are so far away from it. Further, it's unclear why only Sedna (of the two dwarf planets known in that region) has the material. They're too fa...

When I asked the Lord – in view of our historic atmosphere of national and global anxiety and fear – how then shall your people pray and think and act, He led me immediately and serendipitously to a historic event in the leadership of His people. I believe He wants to talk with us a...
ATMOSPHERIC CHEMISTRY IN GIANT PLANETS, BROWN DWARFS, AND LOW-MASS DWARF STARS. III. IRON, MAGNESIUM, AND SILICON We use thermochemical equilibrium calculations to model iron, magnesium, and silicon chemistry in the atmospheres of giant planets, brown dwarfs, extrasola...

we've shown that you can essentially violate something that is a direct consequence of Unitarity. To me, this is an indication that something weird is going on with Deutsch's model. However, there might be some way of modifying the model in such a way that we don't violate the no-clon...
