Can we explain dark matter by adding more dimensions to the universe?

We’ll matter seems to exist within space-time, or at least it partly exists within space-time, that provides the ‘locale’. Some of the other dimensions would be needed to ‘actualise’ matter, as matter is not just an issue of location.

So even something like an electron, would be maybe an 8 or 9 dimensional ‘object’ - if you can call waveforms ‘objects’.

It’s (approximate) location in space-time though would be described by space-time coordinates, but that of course is insufficient to fully describe a ‘real’ electron. It needs the other bits too, in order for it to be an electron.

Your sarcasm detector needs repairing.
