BBC Horizon: Is everything we know about the Universe wrong?

 

Is Everything We Know About the Universe Wrong? is another excellent BBC Horizon documentary.

Cosmology is undergoing a great shift. The traditional Standard Model is unsatisfactory because it does not explain dark matter or dark energy. And the modifications to the Standard Model that do are unsatisfactory because they are inelegant add-ons. Something is missing from our understanding of the universe, and it is either new forms of matter and energy, our understanding of the basic habits (natural laws) of the universe, or a combination of both.

It is another reminder that what we think we know about anything, however elaborate or useful it may seem, is vanishingly small compared to the infinity we do not know. Our experience is always very limited. (*) And our interpretations of this experience is just one of an indefinite number of possible interpretations, some of which would make equally much or more sense to us than the ones we are currently aware of.

Whenever we have a story about something, there will always be something that doesn’t fit. And if this is something that appears significant to us, or if many smaller things that do not fit keep cropping up, it requires us to reorient, to reorganize how we look at ourselves and/or the rest of the world.

It is a continuous process for us at individual and collective levels.
