    The first dimension is pretty simple: a straight line connecting two points, or a length without width or depth. But as Rob Bryanton (on whose workthis list is based) points out, within that apparent simplicity there’s a great deal of complexity. After all, the first dimension isn’t bound by any two points that define its trajectory. It stretches t...

    The second dimension arises from the first with the addition of two extra dimensions, allowing us to move not just forwards and backwards but left and right as well. With two dimensions, we can define a plane — a flat surface with length and width but no depth – extending infinitely like the first dimension in every direction available to it. In th...

    Actually, Abbott used more poetic license in imagining Flatland than even he may have been aware of. Not only would Flatlanders require a third dimension just to see each other as lines, they would also require a fourth, duration. And the same is true for us in the third dimension. That’s because it takes time for the light rebounding off objects t...

    Just as the first dimension is a line stringing multiple zero-dimensional points together, the fourth dimension may be seen as a line stringing multiple Planck frames together. There’s another way to look at this: just as Flatlanders could only see a one-dimensional slice (a line) of three-dimensional beings, so can we only see, at any given moment...

    The previous entry throws up an essential question: If everything you’ve ever done and ever will do is already played out, how can you have free will? The answer, according to string theory, is you don’t – at least, not as you know it. While everything you’ve ever done and ever will do is already played out, so is everything you could have done and...

    Of course, there’s still only one of you per timeline and no way of accessing the others. From the point of the split, each timeline becomes permanently inaccessible from the others because of the same entropy-driven laws that stop us going back in time. And the same is true from the very beginning of the universe – from the big bang – the point at...

    So far we’ve been thinking about a universe of possibilities with the same initial conditions, the same big bang. But what if the starting conditions were different? Such a universe couldn’t feature in the sixth-dimensional phase space of this universe, so there must be another dimension. In the seventh dimension, our universe, with all its myriad ...

    Why do we need an eighth dimension? Because there will always be universes that are not includedalong any seventh-dimensional line we can draw. A line on which the laws of gravity change from universe to universe while every other law remains the same, for instance, will have no universe that has the same gravity as our own but a different speed of...

    Still, you’re going to have trouble getting to any of those other universes in anything less than a ninth-dimensional space ship. Travel from any one universe to another without having to pass through the infinitely diverse intermediate universes to get there requires an additional degree of freedom. Enter the ninth dimension. If the eighth, the ul...

    Take every possibility, no matter how unlikely, happening to every single thing, no matter how tiny, in every moment at any time, occurring all of the time, in every universe of an infinite and unthinkably varied multiverse, and reduce it all to a single point. This is how Bryanton begins thinking about every other dimension – with a point – to fin...

  3. May 12, 2017 · Superstring theory, one of the leading theories today to explain the nature of our universe, contends that there are 10 dimensions. That’s nine of space and one of time. Throughout the 20 th ...

  4. Oct 16, 2021 · There are three dimensions that we experience daily, which define the length, width, and depth of all objects in our Universe (the x, y, and z-axis, respectively). However, scientists maintain ...

  7. May 29, 2023 · What is the 6th dimension called? A way to look at the 6th dimension is from Everett’s Many Worlds Interpretation of quantum mechanics. It presents the 6th dimension as the ‘phase space‘ of the set of parallel universes resulting from our universe’s unique initial conditions (the big bang).
