Adam Frank writes: KEY TAKEAWAYS When you look at a picture of a galaxy that is 75 million light-years away, you are seeing that galaxy at a time when dinosaurs ruled the Earth. Distance translates into time because the speed of light is finite. What you perceive as “now” is really layer after layer of light Read More…
“The insights gathered by [this research] offer a clearer picture of the dramatic events that once unfolded deep within our planet’s interior. They also provide new hints as to how Earth narrowly avoided a Mars-like fate, just as complex, multicellular life was beginning to emerge.”
If the future forms of living organisms are predictable, it will be due to the ensemble of their systems of particles obeying fundamental laws of physics. “Evolution” is not a “law of physics” that is independent of or supersedes other known laws of physics.
In considering “the only important question we can ask”, namely, “What is true?”, can we think of any commonly held theory that matches some of the data, but has had to be propped up by various “epicycles,” and may “lead us even farther astray” by missing a profound understanding of reality?
Marcelo Gleiser writes: “The Multiverse has been proposed as an answer to the question, “Why does our Universe exist?”
Its proponents believe the Multiverse can explain our origins without having to reference God. But the Multiverse is in no way falsifiable, and the arguments in its support are nearly identical to the arguments for God.”
“The simulation argument messes with our self-esteem. It concludes that we have no free will, that we are just puppets fooled into thinking we are free to make choices.”
A Chinese rover has found evidence that there was liquid water on Mars far more recently than we thought — a discovery that could affect plans to one day colonize the Red Planet.
Jenny Morber: Theoretical research suggests that quantum effects could drive mutations in human DNA. This is the latest development in an emerging field called quantum biology.
Ethan Siegel: Thanks to its unique, unprecedented capabilities, JWST might answer five currently open questions about the Universe in very surprising ways.
Theoretical physicist Marcelo Gleiser raises the issue that the multiverse hypothesis suffers from the unscientific property of non-falsifiability. Embedded in his article is a solid acknowledgement of the fine-tuning of physical parameters for life to exist in our universe.
