It's an interactive experience that will sometimes ask you to touch the elements on screen so you can see their labels or to move your phone around so you can see more of what's happening outside the current view. Some parts even need to capture your hand with the phone camera, giving you a more active role in the storytelling process. The app is available for Android and iOS, but it's not listed in the platform's app stores. You'll have to download it from its official web page and make sure your device is compatible -- for Android devices, that means you'll have to install ARCore.

Google Arts and Culture has also launched a new exhibit entitled Once Upon a Try that showcases a millennia of human progress alongside the Big Bang app. The exhibit features hundreds of collections you can view, including a new tool called NASA's Visual Universe that gives you access to 127,000 historic images from the agency. Other exhibits will take you on a 360-degree tour of the Space Shuttle Discovery, CERN's LHC tunnels and the International Space Station. You can view all those and more on the new project's home.
