Is science too much about assumptions?

I think it is interesting. Sometimes we hold on tight too something we think we know that there isn't very much room for something else.

It's currently baseless speculation.

They don't even have a mathematical basis. It's more likely the data is wrong or another explanation. The speed of light being constant has so much evidence it would take equally overwhelming evidence to overturn, not just "wouldn't it be nice if it explained this one thing".

maybe, but einstein had some crazy ideas for his time. We will see. What is in your opinion the biggest assumption in science that is sometimes stated as a fact?
