Given:

a) our present understanding of the universe includes the existence of massive bodies bound by causal relationships

b) time is experienced as the linear progression of causality as experienced by a body with mass

c) causality is limited to that which can be predicted by the Standard Model of particle physics

We can conclude the following:

1) any understanding of the universe that does not include the existence of massive bodies is outside of our present understanding

2) time might not be experienced as a linear progression of causality by a body without mass

3) outside of the limits of that which can be predicted by the Standard Model, causality does not follow the rules of linear time (as has been evidenced by various quantum phenomena, including entanglement and retrocausality)

Therefore:

I) interpretation of the universe in a massive body requires the limits of causality

II) a body without mass is not bound to temporal limits

III) the idea of a body without mass is paradoxical to our present understanding of the universe
