Mars has two moons, Jupiter has 66, Saturn 62, Uranus 27, Neptune 13. But our planet Earth has just one moon. Doesn't it?
Joshua Zintel's insight:
"Earth does sometimes have temporary moons. In March of 2012, astronomers at Cornell University published the result of a computer study, suggesting that asteroids orbiting the sun might temporarily become natural satellites of Earth. In fact, they said, Earth usually has more than one temporary moon, which they called minimoons. These astronomers said the minimoons would follow complicated paths around Earth for a time, as depicted in the images above and below. Eventually, they would break free of Earth’s gravity – only to be immediately recaptured into orbit around the sun, becoming an asteroid once more. The little moons envisioned by these astronomers might typically be only a few feet across and might orbit our planet for less than a year before going back to orbit the sun as asteroids."

One of the most basic laws of quantum mechanics is that a system can be in more than one state -- it can exist in multiple realities -- at once.
Joshua Zintel's insight:
This sheds some light, so to speak, on the false pop quantum mechanics notion that we change the universe simply by observing it; it isn't passive observation that alters quantum spin, but rather the active process of measurement by hitting the system with a laser which causes the collapse of the wave form.

CAPE CANAVERAL, Fla. (AP) — A recently discovered comet is closer than it's ever been to Earth, and stargazers in the Northern Hemisphere finally get to see it.
Joshua Zintel's insight:
"The best viewing days should be next Tuesday and Wednesday, when Pan-STARRS appears next to a crescent moon at dusk in the western sky. Until then, glare from the sun will obscure the comet." Delete the scoop?

(Phys.org)—If an object traveling through spacetime can loop back in time in a certain way, then its trajectory can allow a pair of its components to be measured with perfect accuracy, violating Heisenberg's uncertainty principle. Via Semiotic Sorceress

(a) A closed timelike curve, in which p2 is a chronology-respecting system, and p1 is a time-traveling system that can jump from point tA to the past point tB through a spacetime wormhole, has the ability to interact with itself in the past. (b) In an open timelike curve (OTC), the system cannot interact with itself in the past. In the new study, physicists have theoretically shown that OTCs can violate Heisenberg’s uncertainty principle, provided p1 is entangled with p2. This proposal could be tested by performing experiments on entangled systems in Earth’s gravitational field.
