"How Confident Are We That Dark Matter Is Real?"

"While it is true that dark matter is inferred to exist and we have not confirmed it directly, that inference is very strong and based on multiple observations. It is also currently the best explanation for all these observations. But yes, there is a question mark next to dark matter until we actually discover the dark matter particle. That is why it is an area of active research."


"The Quest to Tell Science from Pseudoscience"

Another article that claims Popper's falsifiability criterion is busted. I absolutely don't get it. There are two claims that supposedly damage the criterion. The first one is real but quite able to be handled. The second one strikes me as absurd. How do flat Earthers and laetrile meet his criterion? Yes, they make falsifiable predictions, but those predictions seem to be wrong. What's the problem?


"Do we have to age?"

I wish Andrew Steele all the luck in the world. He isn't subject to the Stockholm Syndrome some people have about death:

And what about death? At one point during our conversation, I ask Steele if he imagines a time when dying becomes a choice. He thinks the question is overblown. “Because death is inevitable people have rationalised it as something that drives life, or gives life meaning, or adds some sort of poetry to the human condition,” he says. “But I think, broadly speaking, death is bad. If there was less death in the world, I think most people would agree that was a good thing. And though my passion for treating ageing isn’t driven by reducing the amount of death, it’s driven by reducing ill health in later life, it’s driven by conquering disease, it’s driven by getting rid of suffering, if there’s less death as a side-effect? I don’t think that’s a bad thing.”
