The fact that we have found gravitational waves tells us that we have come a long way in terms of science and technology. We detected a perturbation in the fabric of space-time that was one one-thousandth the diameter of a proton. It’s insane to think about that level of precision. And yet we still can’t find Dark Matter, the stuff that is literally everywhere in the universe. Is it our problem? Or is dark matter just on a whole different level? By now, we know that dark matter isn’t some clump of stuff sitting out there in space. But that...
A couple of weeks ago, using the Subaru Telescope, astronomers from the Carnegie Institution for Science discovered the newest dwarf planet of our solar system, which may end up claiming the title for most distant dwarf planet. The object, which isn’t even confirmed as a dwarf planet yet, is called V774104. It resides a distance of 2-3 times that of Pluto, around 9 Billion Km. It is expected to be a little less than half of Pluto’s size, and it may have a highly eccentric orbit, bringing it closer to the Sun over it’s multi-century trip around the solar system. “That’s...
At one point in history, let’s say around 1994, astronomers were fairly confident in their understanding of the formation of planetary systems. Even though at the time we hadn’t found any planets orbiting other stars, they had long been theorized, and we figured that systems would form much like our own solar system. Rocky planets in the interior, gaseous giants further out, and a huge icy debris field at the outer edges. And then along came 51 Pegasi b. Half the mass of Jupiter, it orbits its star in only 4 days, far closer than Mercury. It was considered a...
The finale of the Rubik’s cube challenge was on Sunday, and yielded some interesting results. To confirm, I did not look at an actual cube or picture of one between the start of the challenge last Wednesday, and the finale on Sunday. All I did was read the book on the cube solution. Before I reveal the results let me give you a rundown of what I had to do. To make it work required memorizing a lot of steps, and learning the notation used by the book. In the above picture, the top side (T) is yellow, the Front...
