i read a pretty good article on how its pretty air tight that we are a computer simulation. it was fascinating.

There's a really cool YouTube explanation by Infinite Series explaining the study of these shapes. It's pretty mind bending but fascinating for anyone who wants to learn more about them.

If you can find it feel free to post, I'd like to watch.

The simple answer is.... Yes, absolutely.

Sorry, on my phone. But if you go to YouTube search "infinite series hyper spheres". It's a good series, but that particular episode was relevant to your thread.

Read the Nature article I posted in the OP
quote:In our Universe, a black hole is bounded by a spherical surface called an event horizon. Whereas in ordinary three-dimensional space it takes a two-dimensional object (a surface) to create a boundary inside a black hole, in the bulk universe the event horizon of a 4D black hole would be a 3D object — a shape called a hypersphere. When Afshordi’s team modelled the death of a 4D star, they found that the ejected material would form a 3D brane surrounding that 3D event horizon, and slowly expand. The authors postulate that the 3D Universe we live in might be just such a brane — and that we detect the brane’s growth as cosmic expansion. “Astronomers measured that expansion and extrapolated back that the Universe must have begun with a Big Bang — but that is just a mirage,” says Afshordi.
I see. Thanks.
Makes sense I guess. At least it is easy to visualize in your mind so in that respect it makes sense.
