Curious Kids: what is exotic matter, and could we use it to make wormholes? -
Matter is “stuff”. It is anything that is made up of particles that take up space. Everything we can feel and see on Earth is matter, and it’s usually in one of three types: solid, liquid or gas. This could be the chair you’re sitting on, sea water, or the helium in a balloon.
It’s possible that exotic matter could one day explain some of the mysteries of space. It might be a key ingredient for making a wormhole. Curious Kids is a series by The Conversation that gives children the chance to have their questions about the world answered by experts. If you have a question you’d like an expert to answer, send it to [email protected] and make sure you include the asker’s first name, age and town or city. We won’t be able to answer every question, but we’ll do our very best.Einstein said that matter bends space.
A wormhole is formed by space-time curving in such a way that a tunnel forms between two separate regions in the universe. Where the tunnel comes out into space it is called the “mouth”. A wormhole has two mouths that can be separated by an enormous distance, and the tunnel itself is called the “throat”.
