My mind was blown when I first heard about this idea.
Does our universe reside inside a black hole?
Some people think so, including me. I think at least it’s possible!
I thought it was so interesting I had to make a video…
Here is a video of me illustrating the main idea as I see it: since we know our universe is expanding, then if the space inside a black hole is also expanding (including space within the singularity) then they might be one in the same.
