I'm a complete novice when it comes to astronomy, and that's partially why I'm asking.
But every time I watch a Nova, or read up on it, my brain is unable to comprehend how gigantic they tell us the universe really is.
Knowing very little about dark matter and dark energy, I still want to ask -- is there anyway these things could change the way we understand the universe -- in the idea that the universe is actually much SMALLER than we currently believe?
And if so, are there any current theories or scientists pushing through any schools of thought on this?
I'd like to hear an educated counter-argument to the usual 20th century 'the universe is infinitely expanding' argument. But does one even exist?
