Representative autofluorescence images of olive (cv. Picual), Mediterranean cypress, lily and turnip pollen before (Fig. 1A, B, C and D, respectively) and after (Fig. 1E, F, G and H, respectively) rehydration. Images were obtained with a confocal laser microscope and represent the sum of the fluorescence emitted at 5901650 nm and 650LP nm after excitation at 543 nm (green laser) and 633 nm (red laser), respectively. Different pseudocolours were used to differentiate species. T, trichome. Bars= 100 µm.

Through The Wormhole - S02E06 Are There Parallel Universes?

Imagine you will die tomorrow morning in a horrific car crash. Somewhere far, far away, there’s an exact version of you that got in the same car, drove the same route, and collided with the same commuter. But this other version of you survives to drive another day. It may sound like science fiction, but it’s looking more and more scientifically likely. Somewhere out there, beyond the cosmic horizon, inside a black hole, or as close as an atom’s length away, there could be a parallel universe. If this is the case, how could we ever know? And would we ever be able to pay this universe a visit?
