The Mystery that Keeps Physicists Up at Night | Science's Greatest Mysteries | BBC Select

Some of the biggest riddles and unknowns facing scientists today are investigated in this fascinating documentary series on BBC Select.

Our existence doesn't really make sense. When the universe was created, matter and a substance called antimatter should have obliterated each other. But that didn't happen. If scientists can unravel the mysteries of antimatter, it could help us understand why there is life on this planet and possibly on planets elsewhere. But trying to study antimatter is a fiendishly difficult task.

How could it make it all the way to the detector without contact with a negative charge and disappearing?

Is antimatter the same as dark energy? Are those words interchangeable? Thanks

I find science a fascinating subject but usually the presenter has to get out his/her crayon for me because my brain is not wired to understand what they're talking about. I love oceanography and volcanology. Physics may as well be presented to me in Sanskrit.
