Physics was one I was most rubbish at out of the three in college after chemistry and biology. I still read articles from popular science pages as they cross my news feeds. I saw this one initially on GLP but thought I'd link the original;

TLDR; about something called Causal set theory, that the universe might not have had a beginning. When it talked about re-imagining spacetime as discrete chunk with an inherent limit as to how close they can come together I was wondering what that means for an expanding universe.
Wasn't sure if this is a hijack, not quite the same as the OP.
