WASP-104b is Darker than Charcoal

By analysing the K2 short-cadence data from Campaign 14 we detect phase-curve modulation in the light curve of the hot-Jupiter host star WASP-104. The ellipsoidal modulation is detected with high significance and in agreement with theoretical expectations, while Doppler beaming and reflection modulations are detected tentatively. We show that the visual geometric albedo is lower than 0.03 at 95% confidence, making it one of the least-reflective planets found to date. The light curve also exhibits a rotational modulation, implying a stellar rotational period likely to be near 23 or 46 days. In addition, we refine the system parameters and place tight upper limits for transit timing and duration variations, starspot occultation events, and additional transiting planets.

WASP-104b's albedo was previously thought to be 0.4 (absorbing 60% of incoming light).

    How many Angels can dance on the head of a pin? / Prove the existence of Free Will.

    What you believe is relevant, if you're actually trying to have a conversation. Otherwise, you're just tossing wood on the fire.

    Here's a definition, if you need to know what "Free Will" is referring to. http://www.dictionary.com/browse/free-will [dictionary.com]

    Without it, there can be no meaning to your "choices", and you can't be held accountable for your actions. Since, you had no choice. The idea that we don't have Free Will is akin to the practice of indulgences. Except, you don't have to pay someone to feel better.

    Why does talking logic with you feel like trying to explain mountaineering to an oyster? You're so deep in Dunning-Krugerland you can't even see where my objections are coming from or why they're being made.

    Go back up to that post where I was asking you why an omniscient etc etc etc God needs a plan, and read those words carefully. The supposed attributes of your God-figure make this plan a transparent sham. Make sure you understand the implications of omniscience (as opposed to just knowing a hell of a lot), omnipotence (as opposed to just being really strong) and especially absolute sovereignty (as opposed to just "being in charge") before you respond again.

    Not for nothing is it said that unbelievers take Yahweh much more seriously than his partisans. That is why we tend to be unbelievers in the first place...
