The Giant Magellan Telescope is part of a new generation of instruments currently under construction that will allow scientists to look back in time at the processes that formed the universe. And after a significant delay, scientists have activated the Large Hadron Collider in Geneva- a 16.8 mile tunnel lined with super-conducting magnets that crash protons together. Physicists will ramp up the power until the collisions mimic conditions at the time of the Big Bang. As long as that doesn't create a black hole that eats Switzerland and crushes the solar system, it should tell physicists some pretty interesting stuff.
