Atlantic bluefin tuna can only rub
their eyes in astonishment when this
torpedo snatches their prey in the
water right from under their noses.
The sail fish can reach speeds of
110 km/h, making it almost twice
as fast as its competitors and other
fast fish in the sea.
Danish astronomer Ole
Rømerrecognised as far back as
1676 that light has a quantifiable
speed. With the help of Jupiter’s
moons he calculated that it must
be around 220,000 kilometres per
second. Even though his calculations
were slightly off, this was an
astonishing achievement given the
lack of technology at his disposal.
Light actually travels at around
300,000 kilometres per second.
Nothing in the universe is faster.
