Are there higher dimensions? A question that we have been trying to answer for a few dekades now, but nothing has been proven yet. And is there space without time or time without space?
Because of this, it has to be said that there is no real sequence of dimensions, which is why time, as most people call the fourth dimension, can also be the first or second dimension. And so far we only know our four dimensions, three spatial dimensions and one dimension that is responsible for time. And we can understand these four dimensions quite well. But there are more and more signs that there are more dimensions that we can't imagine.
String theory, for example, requires eleven dimensions. But the string theory is another very complicated chapter. In string theory there are also objects with 0 dimensions which have a one-dimensional extension. But if you are already worried about something like one or even several higher space dimensions, then at some point you might wonder if there is even another time dimension?
With a higher spatial dimension, it would therefore be the case that the space is simply connected to each other by another dimension. Although I don't think this fits into the context that our brain can't even imagine, something like a fourth spatial dimension, because it's only adapted to these three dimensions. Besides, we couldn't even explore something like a fourth spatial dimension. Since we ourselves are only three-dimensional beings and cannot somehow break out of our dimensions.
In mathematics, higher dimensions are no problem at all, because mathematics knows dimensions that go much further, but which can only be used theoretically and have so far no real practical use for us.
But why even think about higher dimensional eventualities? Why aren't we satisfied with our dimensions? The answer is simple: for example, there are forces that only make sense in connection with higher dimensions. Apart from that, the question remains whether space is possible without time and vice versa? Actually not, because if we really want to experience space, we would need time and vice versa, of course we would also need a place, a spatial dimension to experience time.
And then we come to the same result as Albert Einstein with his theory of relativity. He then came to the conclusion that space and time can never be separated from each other and form a related space time and, interestingly, this space time can also be curved. But this will be a topic I will certainly try to explain to you in another article.
But no matter if there is a higher dimensional eventuality or not, we won't really be able to imagine it, or better said: not yet, but perhaps later with time with more understanding o things.
