An object <em>is</em> its relationships.
We recognise distance by virtue of the particular relationships that distance has. In the same way, we recognise time, velocity, temperature, colour, ..., and everything else by the pattern of relationships that these things have with all the other things. - All the way up to plants, animals and people.
A particular pattern leaves, branches and bark enable us to distinguish a pine tree from an oak tree. If we found ourselves in a universe which consisted of nothing but our senses and an oak tree, we wouldn't be able to say anything meaningful about the oak tree.
What shape are its leaves? Well... they are oak tree leaf shape. There is no other leaf with which to contrast that shape. Our ability to compare different tree requires there to be different tree to compare.
A completely homogeneous universe gives us nothing to work with. If the only thing you can see is a bright white light in all directions with no variation in colour or intensity, no information is conveyed to you. Even if your senses register the light, it isn't meaningful.
For us to perceive meaning there must be differences, patterns that can be compared.
