Is Everything We Know About the Universe Wrong?

Another brilliant documentary from the BBC's 'Horizon' series.

There's something very odd going on in space, something that shouldn't be possible. It is as though vast swathes of the universe are being hoovered up by a gigantic and invisible celestial vacuum cleaner.

Sasha Kaslinsky, the scientist who discovered the phenomenon, is understandably nervous: 'It left us quite unsettled and jittery,' he says, 'because this is not something we planned to find.' The accidental discovery of what is ominously being called 'dark flow' not only has implications for the destinies of large numbers of galaxies but threatens to overturn our current understanding of the birth and evolution of the universe.

Does dark flow herald a new era of cosmological understanding, or does it simply mean that everything we know about the universe is wrong?

Thanks Johnny, I have to agree, this one is particularly good.

Good stuff, but I am more than a little annoyed at the terminology and pictures used to display concepts. They use the word "theory" instead of "hypothesis" and show the Big Bang as a fiery explosion. Since this is how a majority of people consume science news, it is no wonder people are so confused about science.

On the second video, an astrophysicist says "everything we've learned, everything we've gathered, is just a theory".

Emphasis mine.

Come on. I know it may seem that I am nitpicking words at the expense of the overall message of the program, but the way this is being presented (perhaps intentionally so) is that scientists don't have a freaking clue as to what is going on. And if that is what I am impressed with, someone who knows better, what then will less scientifically literate people come away with? It's one thing for the producers to play fast and loose, but for an astrophysicist to say those words makes me cringe and wonder what the hell she was thinking.

I enjoyed it a lot too. However, one thing that always grabs my attention is the use of the word "creation". It's bandied about a LOT in this show. Perhaps it's done intentionally to give the religious viewers a bone to gnaw. I don't know.
