If the universe had a limitation to it's size, what do you think would happen, if any particle got near it? 1. The particle would break down into smaller parts. 2. The universe would expand. 3. The universe would blow up. 4. The particle would be repelled, away from the limit line. 5. The particle would be transfered into a different universe. 6. Something else.
