The discussion centers on Einstein's equation E=mc² and the nature of its derivation, emphasizing that it is not merely a guess but a result of applying Lorentz transformations to existing physics equations. Participants debate the significance of units in the equation, arguing that while units are human inventions, the relationships between mass and energy are fundamental. The conversation touches on the arbitrary nature of different measurement systems, with some expressing frustration over the complexities of non-metric units. There is also mention of Einstein's struggles with mathematics and his initial resistance to certain aspects of his theories, such as the expanding universe. Ultimately, the dialogue highlights the interplay between theoretical physics and the practicalities of measurement.

I remember he rejected a major part of his discoveries, but I don't remember which. He refused to believe, I think that the universe was expanding.

You're thinking of his original model of the universe that included a cosmological constant. He later said it was a mistake to include it because the observations showed an expanding universe. This implied that he believed those observations. However, I think he had a problem with black holes. I'm not an expert on the history.


Why is this? Science is absolute is it not? Once you prove something, its proven and should be accepted?

He didn't prove that his theory applied to all situations. It probably doesn't. Newton's certainly didn't.
