we dont know 🙂 that’s the fantastic thing, we just dont know. There are many theories, such as a space-time foam (like bubbles in the bubble bath) or multi-verses, an infinite universe where the laws of physics change from one place to another, maybe even aliens using our universe as marbles.
The sad thing is, unless we discover FTL (faster than light) space travel, we will never be able to get out of our balloon to see
