I've been day dreaming about this idea for a month or two. There are many hypothesises that describe the universe in some higher number of dimensions. As far as I know, this is always an integer number of dimensions.(adsbygoogle = window.adsbygoogle || []).push({});

I've been wondering if it is possible for the universe to have a fractional number of dimensions, say 3.139 dimensions, where there are 3 spatial dimensions plus the 0.139. The 0.139 could be time. It's fractionality would explain why it seems to behave in a different manner than the other dimensions.

The flow of time could actually be the dimensionality of the universe increasing towards four dimensions. In other words, time is inflating into a full dimension. This would also explain why the universe is expanding because

[tex]

distance = \sqrt{x^2+y^2+z^2+t^2} > \sqrt{x^2+y^2+z^2+(t-\alpha)^2}

[/tex]

and because t is increasing. In reality, time would have to increase at a rate of (if I did my math right)

[tex]t(\tau) = \frac{1}{2}\tau^2[/tex]

to account for linearly expanding space. This leads to a time-dependent distance formula given by

[tex] distance(\tau) = \sqrt{x^2+y^2+z^2+\frac{1}{2}\tau^{2}w^{2}} [/tex]

But this is more in the finer details.

Conversely, it could be that time is actually moving backwards and the dimensionality of the universe is decreasing. This would easily explain the relatively even distribution of matter in the universe. In this case, the perceived expansion of the universe could be some kind of "conservation of space."

I just thought that this was interesting because it unifies space and time, and it also explains why the universe is expanding.

I'm not posting this to the personal research forum because it is largely speculative, and I'm really looking more for comments and criticism.
