Some infinites have to be bigger because infinities are not quantities. It is easy to understand that some functions grow faster than others as input grows. The function that grows faster becomes an infinite to a higher order, even though they both approach infinite, which just means it grows faster as the input size increases

If you can’t understand that try to imagine and endless waterfall and an endless bucket. There is finite matter in the universe but that has nothing to do with the illustration. If you compare the water poured out at a moment in two identical empty basins, the volume of water under the waterfall will be greater. Or if the basin under the waterfall has a tanker full of water in the beginning, it will be greater. But if you look some time later, you will notice that the basin under the waterfall increased in volume more than the basin under the bucket. Therefore the waterfall increases the volume faster than the bucket, and the more time we give it the more volume it will add. It will be an infinite of a higher, because infinite is not a fixed quantity.
