What are some common misconceptions about space?

One common misconception is that you can hear sounds in space, but it's a vacuum, so sound can't travel.

That's interesting! What about black holes? Are they like cosmic vacuum cleaners?

Not exactly! Black holes don't 'suck' things in; objects need to be very close to be affected by their gravity.

I've heard that the Great Wall of China is visible from space. Is that true?

Actually, that's a myth! The Great Wall is hard to see from low Earth orbit without aid, just like many other man-made structures.

What about the idea that we only see one side of the moon?

That's true! The Moon is tidally locked with Earth, so we only see one hemisphere from our planet.
