On the Tired Light Hypothesis

The first model of cosmology that I was exposed to, as a small child, was that of the static universe, because that's all my father knew. According to that model, the universe is infinite in all directions, it is eternal, and it is not going anywhere. Of course I accepted it, because that is what kids do: accept everything presented to them as fact.

Then, during elementary school, I heard of the Big Bang and the expansion of the universe; this new model of cosmology made me feel a bit uncomfortable, but again I accepted it, because a) that's what the scientists said, and b) I could go to my father and tell him that he is wrong.

On the evolutionary origin of reasoning

Biological anthropologists generally agree that humans evolved reasoning to facilitate hunting together as a group; however, there are many other species that hunt in packs, and yet reasoning is unique to humans. Therefore, in order to explain reasoning, it is not enough to consider how it was beneficial to us; we also need to consider what enabled reasoning to emerge specifically in humans as opposed to any other species.

I have a hypothesis which attempts to explain how this happened.

The 'gay gene' paradox

What causes homosexuality? The predominant understanding is that the causes are genetic, but this seems to be in conflict with the notion of natural selection: an individual who does not reproduce is a dead-end for the genes that they carry; therefore, the 'gay gene' should have gone extinct. A number of hypotheses have been proposed, attempting to resolve this paradox, but they are not very convincing. In this post I present a couple of my own hypotheses, which I believe do a better job at resolving the paradox.
