Question: would it ever be possible to travel inter dimensionally

I’ll be honest, I don’t have a clue! We understand so little about space – we don’t even know what shape it is or what makes up most of it. I’d be very happy to find out myself!

What I would say though, is that you don’t just have 1D, 2D and 3D dimensions. Computer programmers (like me!) often use 4 and 5 dimensions to make their programs faster. One of the biggest things in computing at the moment – machine learning (what I study!) works by trying to find how you can separate things based on their dimensions, and there can be millions of dimensions in the maths. Understanding these dimensions is how Google make their phones take amazing pictures, or how things like Siri, Alexa, Google Now and Cortana understand and respond to you.

We also have dimensions that aren’t whole numbers, either (so 2.5D, 1.3D, and so on). There’s a really famous thing called the mandelbrot set – do a youtube search for it. You can make a shape that goes on forever, no matter how far you zoom in. That’s travelling inter dimensionally! We also think good musicians or different types of music (rock, pop, jazz) may have different dimensions, and it may be those dimensions that make our brain “like” or “dislike” music. And if you understand this, you can make music that people are mathematically forced to like! I got to research this when I was doing my degree – we still don’t know for sure.
