AI Thread Summary
NASA has discovered a planet, Kepler-16b, that orbits two suns, reminiscent of Tatooine from Star Wars. The discovery highlights the planet's unique orbital dynamics, as it rotates counterclockwise relative to its red dwarf star. Some confusion arose regarding the animation depicting the planet's rotation, which was created from an opposite vantage point. This finding expands the understanding of planetary systems and the potential for similar celestial bodies. The discussion emphasizes the significance of accurate representation in scientific animations.

But in the animation, the planet rotates counter clockwise to the rotating red dwarf.

The animator was imaging it from the opposite vantage point.
 
https://en.wikipedia.org/wiki/Recombination_(cosmology) Was a matter density right after the decoupling low enough to consider the vacuum as the actual vacuum, and not the medium through which the light propagates with the speed lower than ##({\epsilon_0\mu_0})^{-1/2}##? I'm asking this in context of the calculation of the observable universe radius, where the time integral of the inverse of the scale factor is multiplied by the constant speed of light ##c##.
Why was the Hubble constant assumed to be decreasing and slowing down (decelerating) the expansion rate of the Universe, while at the same time Dark Energy is presumably accelerating the expansion? And to thicken the plot. recent news from NASA indicates that the Hubble constant is now increasing. Can you clarify this enigma? Also., if the Hubble constant eventually decreases, why is there a lower limit to its value?
