Yeah same here, I think you have to capitalize "Days" even though that makes no sense.

88 has been fixed. Capitalization & punctuation are never required on JetPunk.

I'm sorry but you must have typed something other than "88". "88" definitely works.

I agree, great quiz, but concerning the 88 issue, maybe its just a glitch in the system or something like that, as it didn't work for me either.

Accept magnetar for neutron star? It's more accurate in this case

I have to agree with both Jlf and Ryan 6:

A galactic year needs to be an acceptable answer for the name of the sun's revolution around the galactic center. The term is far more common than 'Cosmic Year.' I have no idea how you wound up making the less common usage the ONLY acceptable one.

And magnetar should be acceptable for the magnetic question. I know that 'magnetar' is right in the name, BUT that is the most common name for the very specific type of neutron star that results in the magnetic thing in the universe - magnets so strong that they would rip the very fabric of reality apart and destroy our entire planet if were were too close.

Dark Matter only accounts for 27% of the universe. I think you are adding dark matter and energy together as together they account for 95%; however, dark matter on its own is not 95%, and thus the question is erroneous.
