Sabine Hossenfelder dismisses fine-tuning; Brian Miller and Steve Meyer respond

Fine-tuning of the universe is one of those concepts that can pass every possible evidence test and still be rejected because it is just not supposed to be true. No matter how foolish the arguments against it are, they will always appear preferable. If the situation results in confusion, well, confusion is clarity. Read More ›

Sabine Hossenfelder Promotes Determinism

Yesterday theoretical physicist Sabine Hossenfelder became the latest in a long line of smart people to make the absurd claim of determinism, and that therefore there is no such thing as free will. This silliness traces at least as far back as Laplace and is based on the idea that any system evolves from time point 1 to time point 2 according to the laws of nature. As Hossenfelder puts it: (read more …)

Sabine Hossenfelder: Flat Earthers are wrong but not stupid

Hossenfelder: It is not possible for each and every one of us to redo all experiments in the history of science. It therefore becomes increasingly important that scientists provide evidence for how science works, so that people who cannot follow the research itself can instead rely on evidence that the system produces correct and useful descriptions of nature.

Sabine Hossenfelder: Einstein’s greatest legacy was the thought experiment

She notes that one needs evidence from real experiments to demonstrate that the outcome of a thought experiment is real. But it is significant that the human mind is capable of developing the basis for momentous discoveries even before we commit to stuff that requires a budget. Read More ›

Sabine Hossenfelder asks: Do we need a theory of everything?

Hossenfelder: So this whole idea of a theory of everything is based on an unscientific premise. Some people would like the laws of nature to be pretty in a very specific way... This is simply not a good strategy to develop scientific theories, and no, it is most certainly not standard methodology. Read More ›

Sabine Hossenfelder says predictions are overrated; Rob Sheldon responds

Sheldon: … ironically, most of Sabine's blogs are about the poor predictive power in particle theory, but in this blog she feels she has to reverse herself to defend the good name of global warming. My advice to her is to stick with what she has first-hand knowledge of, because 2nd-hand knowledge always suffers from authoritarian bias. Read More ›

Sabine Hossenfelder: Are dark matter and dark energy scientific?

Hossenfelder: “So, what’s the scientist to do when they are faced with such a discrepancy between theory and observation? They look for new regularities in the observation and try to find a simple way to explain them.” Okay but the question of whether the terms “dark matter” and “dark energy” correspond to anything that actually exists could be a different one.

Sabine Hossenfelder slams panpsychism

Electrons cannot be conscious Sabine Hossenfelder’s view because they cannot change their behavior. Hossenfelder’s impatience is understandable but she underestimates the seriousness of the problem serious thinkers about consciousness confront. Read More ›

Sabine Hossenfelder asks: Does nature have a minimal length? Could it point to a final theory?

Hossenfelder: What does this all mean? Well, it means that we might be close to finding a final theory, one that describes nature at its most fundamental level and there is nothing more beyond that. That is possible, but. Remember that the arguments for the existence of a minimal length rest on extrapolating 16 orders magnitude below the distances what we have tested so far. That’s a lot. That extrapolation might just be wrong. Read More ›

Sabine Hossenfelder makes it to Slashdot

Hossenfelder: What we have here in the foundation of physics is a plain failure of the scientific method. All these wrong predictions should have taught physicists that just because they can write down equations for something does not mean this math is a scientifically promising hypothesis. Read More ›
