== Abstract ==&lt;br /&gt;
This paper explores some surprising connections between the frequencies of light we observe and foundational&lt;br /&gt;
questions in the mathematics of real numbers and the theory of computation. We find that these foundational issues&lt;br /&gt;
imply limitations on what can be seen, separate from any limitations from the laws of physics. Furthermore, it&lt;br /&gt;
turns out that, given the kinds of observations one can make of light, the most reasonable expectation for the actual&lt;br /&gt;
frequency of light underlying any set of observations is that that frequency comes from a particularly unusual class&lt;br /&gt;
of uncomputable numbers called generic real numbers.&lt;br /&gt;
