Now that gravitational waves are definitely a thing, it’s time to think about some of the crazy things we can figure out with them. In some cases we’re going to need a gravitational wave observatory - in fact, we've already built one.
On a cosmic time scale, human history is as brief as the blink of an eye. By compressing all 13.8 billion years of time into a 10 minute scale, this video shows just how young we truly are, and just how ancient and vast our universe is. Starting with the big bang and culminating in the appearance of homo sapiens, this experience follows the unfolding of time at 22 million years per second, adhering closely to current scientific understanding.

Kevin explores and probes second by second what it takes to 'lift off' into space. With Tim only days into his six-month mission, he helps Kevin answer what keeps astronauts safe and on track as they are propelled into orbit. How do you control the energy of 300 tonnes of liquid fuel? What happens to your body if you don't wear a spacesuit? And how do you catch up with a space station travelling at 17,500 mph to finally get inside? With explosive live experiments, guest astronauts in the lecture theatre, and planetary scientist Monica Grady direct from the launch pad in Kazakhstan, we learn all this and more as those thrilling minutes of lift off are recreated.
New discoveries reveal an astonishing supermassive black hole that was born during the earliest days of the cosmos, and finding out how this giant grew so large so quickly may help to explain the very formation of the universe itself.
