The discovery of the fundamental particles of the Universe allowed physicists to gain a new insight on what the conditions during the Big Bang was like. Using particle accelerators, physicists are able to imitate the extreme conditions that occurred a fraction of the nanosecond after the Big Bang. Particle accelerators such as SLAC and the Large Hadron Collider (LHC) in particular are specialised at testing the different theories of particle physics.
If you think it is impressive that primates have managed to survive on Earth for 50 million years, then you will find it phenomenal that trilobites managed to survive for a staggering period of 270 million years. First appearing on Earth about 521 million years ago during the early Cambrian period (when life on Earth began to complexify in incredible ways), they finally became fully extinct around 252 million years ago, during the late Permian period, and were probably the most abundant animal on Earth at that time. This is one testament to their immense success as an organism; another being the fact that their fossils are found widely dispersed on Earth – on every continent in fact – and palaeobiologists have named over 15,000 species of trilobites. So what made them so successful as an organism?
