Can you add to what degree for the "How old is the universe" question. was trying 13 billion and 14 billion but wasnt sure if i was completly wrong or just entering it wrong.

Nice quiz

I tried variations on spelling and numbering 13.7 billion years, since that's how old it was said to be in my day. Apparently it's now 13.787±0.020 billion years, which should still be close enough for 13.7 to work.

It's silly to want to be that specific when you know that number will be revised in our lifetimes anyway.

Could you also accept 100km above sea level?

The question re the age of the universe should be more precise - either round it up or specify to decimal points.

Agree. Needs clarity.

you should probably ask about the nearest "spiral galaxy" rather than the nearest galaxy. Milky Way is orbited by 61 known satellite galaxies, several of them closer to the earth than the diameter of the milky way, so you would need to ask about the closet galaxy to earth rather than the milky way. The closest galaxies to Earth are Sagittarius Dwarf, Ursa Major III, and Canis Major Dwarf.

"What is a star explosion called?" should be more specific. There are two types of star explosions. A nova is when the star is not destroyed and a supernova is when it is destroyed. Maybe reword the question to "What is a star explosion that destroys the star called?"?

Floccopus is correct, Andromeda is not the closest galaxy... not even close actually.
