Our view of the universe is limited.
Therefore our knowledge of the universe is limited.
Knowledge constantly changes by time and location.
There will always be some unknown areas.
Therefore it is impossible for any agent to know any truth with certainty.
Therefore an absolute truth cannot exist.
Perhaps this can be the case for knowing agents, but can this apply to the universe itself, eg. physical laws? Perhaps the universe itself consists of knowing agents alone and its operation built from their experience and utility. Where are the laws of the universe written? Perhaps in the actions of agents alone, for if written, any rule would require space for data; perhaps the principles of knowledge are the same everywhere. The implications are that the universe itself is ignorant of its laws, no better than human scientists, and that all agents of the universe are in a state of experience and discovery on par with ours.
