"Infinite" means there is no end. Infinity is a term people use when they just don't know when there will be an end. Or whether there will be an end at all.

Our sun sends us rays of light every day. This light travels about 8 ½ minutes from the sun to our earth. Further away is the Andromeda Galaxy. Andromeda can barely be seen with the naked eye. Amazing actually, because Andromeda is over 2 million light years away.

That is, the light we see today was on the move for 2 million years before it reached us on earth. And although this long time may seem endless to us, it is not infinite, but limited: 2 million light years, nothing more.

### Infinity is endless

"Infinite" means there is no end. Infinity is a term people use when they just don't know when there will be an end. Or whether there will be an end at all.

Mathematically, one speaks of "infinite" when something is greater than any number there is. There is a larger number for every number: because you can add 1 to every number and you get another larger number. The mathematical symbol for "infinite" is therefore not a number, but this symbol: . This lying "8" could be traced indefinitely with your finger.

Not only in mathematics, but also in geometry there is "infinite": If you walk a distance and never encounter an obstacle and keep going, the distance that lies in front of you is also infinite. One step at a time, always further. Go on forever.

For the universe, "infinite" means: We do not know whether the universe has an end. Because we can only see one area of ​​the universe or recognize it with technical devices. Namely the area from which light comes to us. Beyond that, it will certainly continue.

But we don't know how things will go on. We can only speculate about this. The universe may indeed be infinite. Simply because nothing stands in the way and it goes on and on.
