Technically, Charon isn't a moon - it and Pluto are a binary system (the center of mass lies outside of Pluto).

I think olypmus should be acctepted. The word mons just means mountain, and that is allready in the question.

Still I got 18/25 right. Not bad, may be not good amongst science enthousiasts, but if you ask a random person on the street I would estimate the score would be about 2/25

(didnt think of quasar or exoplanet, mind went to something made up like extragallactical (planet) haha. The exponential growth one is expansion/ expanding in my language, couldnt think of anything else. And the hawaii, hubble and gamma ray burst I really didnt know)

I disagree with the answer in "The C in E=MC^2 stand for this." In this equation, the C can only be the speed of light, and physics uses the letter C to denote it. No other constant works in this equation.

Not a bad quiz; I got 24 out of 25 with the exception of the Hubble picture because I said extreme deep field, which apparently does not work. Cool quiz though. I would love it if you made another!

There are two errors in this:

"The C in E=MC^2 stands for this"

Actually, it "stands for" the speed of light.

Also Hawking did not "unify" work of Einstein with quantum mechanics (odd phrasing since Einstein was one of the founders of QM). No one has.

Hubble's "most famous photograph" is actually "Pillars of Creation," just thought you should know.

And even if you are not changing that, the deep field image's official name is actually "Hubble Ultra-Deep Field," not just the "Ultra-Deep Field."

This quizz needs to be corrected.

C means celeritas and is the speed of light and does not mean constant (even if it is one).

"H2G2" shall be accepted as "Hichhiker guide" and not hichhiker's as it is not entitled that way.

I've never heard that about Hawking.

In an astronomy quizz, Kepler is mort expected than Newton for the three laws of motion.

Fun quiz, but needs corrections.

Einstein did not discover time dilation. Several other people proposed that effect as a means to explain the Michelson-Morley experiment. Wikipedia mentions Larmor and Cohn in particular. Einstein later showed that time dilation would be a *consequence* of his Special Theory of Relativity.

In answer to "unified Einstein's work with quantum mechanics?", you need to make clear which work you're referring to. If Special Relativity, the answer is Dirac, though partial credit would be deserved for Klein and Gordon. If General Relativity, the answer is no one, at least not yet. If the photoelectric effect, the answer is Einstein himself. Hawking is not a correct answer to this question for any of Einstein's work.
