I tend to agree with the theory that we exist in a digital universe.
Physicists have a lot of problems answering questions regarding time and matter breakdown.
Our perception limitations is another very valid point. We only perceive 4 dimensions. What about the other 5 or 6?
I think the word “dimensions” tends to obscure more than it clarifies.
Example: an ant could look at a human and be unable to make sense of what they are seeing—even though we are both in the same “dimension”.
We (and ants for that matter) interpret everything we experience with templates/narratives/models.
If those are wrong—all bets are off..
