minus-squareHubertManne@piefed.sociallinkfedilinkEnglisharrow-up0·2 months agoI sorta think its still possible. Im not 100% sold gravity is a constant on massive scales.

minus-squareFUCKING_CUNO@lemmy.dbzer0.comlinkfedilinkarrow-up0·2 months agoThe moment before the big bang, the universe was a singularity similar to a black hole though. In fact, our universe shares several properties with black holes (mass/energy can never escape it, for example)
