I'm making a space game and need help with an idea

I’m making a space game a kind of mix between outer wilds, sea of thieves and lethal company. In the centre of the universe there is a mix of a gravitational and cosmic singularity as well as some other things. However as a singularity has no confirmed visual look I want ideas of how it should look.
For those who don’t know what a singularity is. A cosmic singularity is the theorised thing before the big bang it has infinite temperature and also is infinitely dense.
A gravitational singularity is theorised to be in the middle of a black hole it has infinite mass and is infinitely dense.
