High Speed Pictures

Is it possible to take high speed pictures with your ordinary DSLR, like my Nikon D60?

Grand Tack Theory

The formation of our solar system could explained by the Grand Tack scenario. In this scenario in the early solar system Jupiter and Saturn migrate inwards towards the sun and then back outwards. Those migrations could explain the existance of the Kuiper belt, the Oort cloud but also the late heavy bombardment.
