How is the universe constantly expanding ?

511 views

I don’t understand the concept behind the fact that the universe is infinite and that it is always expanding.

In my mind: something expanding assumes that there is space for it to go into, and if that space existed previously, it can’t really be considered an expansion since it was already there.

Perhaps I have misunderstood what is meant through the term ‘expansion’ in this case or made an incorrect assumption, I’d appreciate if anyone could clarify the process for me.

We don’t know. Theories are thrown around involving dark matter, multiverses, that we’re in a black hole that distorts out detections at a distance…

But the truth is that our human senses can only perceive a small piece of the entire spectrum of light and sound. And then our greatest monitoring systems extend our ability to perceive beyond those limits, but even they only communicate on the spectrums that we know about and can theorize.

Your answer is that we see the universe as expanding, we don’t know why, and what we see and what we know are most definitely only a small piece of what actually Is.
