^{Can a star turn into a planet?}

^{Can gravity form waves?}

^{Does every black hole contain a singularity?}

^{Does sound travel faster in space?}

^{Does the influence of gravity extend out forever?}

^{Galaxies look stationary, so why do scientists say that they rotate?}

^{Have aliens ever visited earth?}

^{Have astronomers ever observed a violet shift like they have blueshifts and redshifts?}

^{How bright is a laser beam when viewed from the side?}

^{How can astronomers know things for certain since they only look at space from one vantage point?}

^{How can there be anything left in the universe? Don't black holes suck everything in?}

^{How can you cancel out the jolt of a quick start?}

^{How can you tell a black hole made out of antimatter from a black hole made out of matter?}

^{How do space probes make it past the asteroid belt without crashing into asteroids?}

^{How do space ships fly faster than light?}

^{How do space ships make artificial gravity?}

^{How do stars move when viewed from a speeding spaceship?}

^{How does a black hole give off light?}

^{How does a supernova destroy a star?}

^{How does astrology work?}

^{How does looking at distant galaxies allow us to look back in time?}

^{How does the expansion of the universe make outer space a vacuum?}

^{How large would a bucket of water have to be to put out the sun?}

^{How long before the expansion of the universe causes our earth to drift away from the sun?}

^{How long can a human in outer space last without a spacesuit before exploding?}

^{How often does the sun's magnetic field flip?}

^{I know that the gravity of the moon causes ocean tides on earth. How does the centrifugal force cause the far-side bulge?}

^{Is Pluto a planet?}

^{Since a star's light takes so long to reach us, how do we know that the star is still there?}

^{Since one satellite can see half of the earth, why do we need more than two satellites in a given network?}

^{Where is the edge of the universe?}

^{Which space movie has the most accurate physics?}

^{Why are all the stars fixed in space?}

^{Why are stars not blurred even though the earth is moving?}

^{Why did NASA spend millions developing a pen that would work in space when a pencil is just as good?}

^{Why did people believe the earth is the centre of the solar system when it's obvious the sun is?}

^{Why do the spikes that shoot out of stars form perfect crosses?}

^{Why does everything in our galaxy orbit the supermassive black hole at the centre?}

^{Why does the moon get bigger when it's closer to the horizon?}

^{Why does the moon's gravity cause tides on earth but the sun's gravity doesn't?}

^{Why does the sun not run out of oxygen as it burns?}

^{Why doesn't the earth fall?}

^{Why don't galaxies have a natural magnetic field like the earth does?}

^{Why is gravity the strongest force?}

^{Why is the moon so bright?}

^{Why is there no gravity in space?}

^{Why is there no up and down in space?}

^{Will the night sky eventually end up completely black because the universe is expanding?}

^{Would a guitar sound the same on a space station?}
