Imagine an universe where time exists in 3 dimensions like our space dimensions and space is one dimensional. let's call it 1+3 universe In that universe a black hole is created. Beyond the event horizon the dimensions flip occures where time only goes towards the "singularity" and freedom of movement is only in the space dimensions. We have now a 3+1 region that should match what would be expected in our universe. With definite begining low entropy state like during the big bang. Are we living in the "time black hole"? #science
