How can the universe be infinite and expanding?

Question

Nova Adams · Accepted Answer

The Universe is not considered infinite but finite and unbounded.

The expansion of the Universe can be deduced from the red shift of distant galaxies, as space-time unravels with the passage of time.

Asher Cohen · Answer

undefined The universe may be both infinite and expanding at the same time because the expansion of the universe is defined as the growing separations between galaxies, whereas the idea of infinity implies that the universe is limitless.

undefined Let’s break it down step-by-step:

1. **Universe is Big:** The universe is so big that we can’t see all of it.

2. **Expanding:** The universe is getting bigger all the time. Imagine blowing up a balloon. As it blows up, the surface gets bigger.

3. **Infinite Space:** Even if it is getting bigger, there are still parts of space that are so far away, we call it infinite.

4. **No Edge:** It doesn’t have a wall or end; it just keeps going.

5. **How It Works:** Think of dots on a balloon. When the balloon gets bigger, the dots move away from each other. The dots are like galaxies.

So, the universe can be infinite and expanding at the same time!
