C'mon, we can already transmit data across different dimensions using a wrist watch & morse code. Yeah, bandwidth isn't that great but hey, we could use a wall

I know you are joking, but transmit information through dimensions using gravity is one interesting conjecture why gravitational force is so much weaker than the other forces. It leaks through dimensions. And maybe this type of communication will be necessary when we have to leave this dimension to hyperspace because of the entropy [1].

  For what it’s worth, evidence has come out (explained well by this PBS Space Time episode [1]) that makes the “gravity propagates over more than three spatial dimensions” theory a bit less likely. [1] https://youtu.be/3HYw6vPR9qU https://youtu.be/3HYw6vPR9qU

    Interesting video, so it is possible that there is no leak after all, but I think this does not prove that there are no extra dimensions, as the video tries to portrait.

  The 3+1 dimensional spacetime is not embedded in a higher dimensional space [1]. If there are additional dimensions, they have to be "rolled up" and tiny. [1] http://iopscience.iop.org/article/10.1088/1475-7516/2018/07/048/meta http://iopscience.iop.org/article/10.1088/1475-7516/2018/07/...

    I wish I could read a paper like this one! My takeaway is that is no leak, but this doesn't prove that there are not higher dimensions in space, just that the gravitational waves can't get through it (if exists).

I think tweaking the ribbon of space time abstractions in a tesseract while wearing a space-suit to talk to your younger daughter, must have been a totally amazing moment to "sell" to the movie pitch guys. Selling it as Matthew McConaghy must have been doubly fun: No... we wanted Kevin Kostner <click--brrrrr as phone gets dropped>
