Comment Re:So of course, they just ASSUME it is a water pl (Score 2) 134

I don't think you actually read the stories. The sensors did not "detect water". They sensed some anomalies in magnetic field and plasma density which defied any obvious explanation at the time (in 1997). These scientists did some modeling and showed that those signatures can be explained by the presence of a water plume. That is certainly interesting and supports the conclusion that Galileo may have passed through or very near a water plume, however it is very different from saying that "the sensors detected water".

I think you have completely misunderstood the scale of time dilation. you really should do the math! Time dilation doesn't matter at all at the orbital speeds of planets that we are talking about, and the gravity wells aren't deep enough either for any realistic configuration of habitable planets (there is a reason "Interstellar" had to put that planet in orbit around a supermassive black hole)

I know what you mean, but saying "For light, dark matter just isn't there" isn't quite right. It isn't there in terms of electromagnetic interaction. The gravity, on the other hand, can't be escaped even by photons. Otherwise you wouldn't have seen the lensing effects that are some of the best evidence for dark matter's existence.

How does you Occam's Razor calculation change when you consider that this is based on chemical analysis of the same suspected flowing water streaks that were observed years ago (and published in Science 4 years ago http://www.sciencemag.org/cont... ). These streaks (called RSLs) have been continuously studied - and results published - since then with everyone being almost sure that the best explanation (Occam's Razor!) has to be flowing water. And yet, the scientists and NASA waited for the final clinching confirmation based on spectroscopy before making this announcement. You think they hastily concocted some story to get funding? You have no idea how these things work!

I had never bothered to make this calculation, but always sort of assumed that the Sun would look like a disc from those distances... very small but still with a disc shape easily discernible by naked eye. This made me do the calculation. Turns out that the Sun looks almost exactly the same size from Pluto (at perihelion) as Venus does from Earth (at their closest distance)! However, venus at its closest is bright enough to cast discernible shadows and Sun's absolute brightness is a LOTTTT more than venus. So, yes, you are right. just another star in the sky that is however *much* brighter than anything else. For religions starting on pluto, you can easily bet against anything other than the Sun or Charon being their chief deity.

Comment Re:Wait.. HALF THE WORLD?!? (Score 1) 48

I agree that it is a bit confusing. That number seems impossibly large. Perhaps they mean "number of passengers" which means that the same person making 2 return trips might be counted as 4 passengers? It is like saying "New York City's subway serves X million passengers per week", where every single person is probably counted multiple times based on the number of trips they make.

Comment Re:Is this the missing "dark matter"? (Score 1) 85

Here is something to boggle your mind. You think your argument is strong with Sun containing 98% of the Solar system's total mass? It is actually something like 99.8%!! to think that stray jupiter-size brown dwarves can weigh anywhere near the total stellar masses that we see betrays complete lack of understanding of the difference of scales involved.
