There are 10 dimensions, I just learned this.
That is all.
There is an infinite number of dimensions.
No, there are 10.
This is interesting and all but it's a physicist's way of looking at dimensions.
Any mathematician will tell you that you can have as many dimensions as you want.
...and that's the bottom line because Mate de Vita said so.
Who controls the past, controls the future. Who controls the present, controls the past.

Well I'm talkin' about physics, not math
And, as I see it, teleportation as well as time travel is definitely possible, according to that video.
According to that video is the problem. There is a theory, like a framework, called String Theory. It purports that in some way the Universe has more spatial dimensions than we can easily observe. Some formulations say ten, others eleven, and there is one that says twenty-six, though only if you are rotating to the right.
Mate de Vita is being a bit sneaky, he was not necessarily talking about spatial dimensions. For instance, finite bodies, essentially anything of normal human size on Earth, live in a six-dimensional space. They have three co-ordinates describing their position relative to some origin and another three describing their rotation, relative to same. If you have two such objects, you can describe them in a twelve-dimensional space. Mathematicians also frequently consider objects in systems with many spatial degrees, it makes life interesting.
The problem is that there are people that just call themselves scientists and then start making shit up to get grants... or possibly fame... or maybe they're just crazy, I don't know. String Theory is a shining example of that.

Also math is kind of science about stuff that has been created by humans, so you can basically make anything with it. It won't necessarily resemble reality though.
String Theory is so unbelievably stupid I'm not even going to make any arguments against it. It'd be like arguing against the Flying Spaghetti Monster. Arguing against it would give it too much credit.
Special and general relativity are entirely consistent, it's quantum mechanics and general relativity that have issues.
In what way is it "stupid"? It's actually rather a neat idea at its core (particles behave like 1D strings trying to minimise the area of their worldsheets, which reflects the Principle of Least Action nicely), but sadly all sorts of things need to be added to make String Theory more consistent with our Universe. It also makes a whole bunch of predictions that are a bit... dodgy. Some very nice symmetries though.
As I mentioned. I won't give it the credit of arguing about it, it's beneath me... and I'll argue about practically anything. Even the name is stupid. It's not a fucking theory. How do they even get off calling it that?
