A really strong magnet can dissolve Everything
One wrong thing everyone knows about the universe is “conservation of matter”. It seems obvious: if you have a chair, you can move it, or turn it around, and you still have one chair. If these were the only experiments you did, you might proclaim that the number of chairs in the universe always stays the same.
Of course, it doesn’t take much thought to counter this: with a hammer you can easily change the number of chairs in the universe. But if you collect every splinter of leftover wood, you’ll find the same amount before and after the destruction.
