    I was one of the people who thought there might be many dimensions, like 10, 11, or 26. But it turns out there are just 4. 3 of space and 1 of time. Now I'm not sure what to believe. Does this seem strange to you too???

    Yes. "Turns out there are just 4." Humans know that because they've been far and beyond in a thousand Galaxies.

    It's probably only 4 dimensions at large sizes ...

    If extra dimensions do exist, they must be really, really small

    ... but apparently this doesn't rule out 10+ dimensions at small scales.
