Black holes are one of the most destructive forces in the universe, capable of tearing a planet apart and swallowing an entire star. Yet scientists now believe they could hold the key to answering the ultimate question - what was there before the Big Bang? The trouble is that researching them is next to impossible. Black holes are by definition invisible and there's no scientific theory able to explain them. Despite these obvious obstacles, Horizon meets the astronomers attempting to image a black hole for the very first time and the theoretical physicists getting ever closer to unlocking their mysteries. It's a story that takes us into the heart of a black hole and to the very edge of what we think we know about the universe.
Playback servers
Subflix keeps extra fallback servers tucked away by default, and if one stalls it will still try the next available option.
Now playing
Strong fallback server when you want a second path ready without leaving the page.
If the provider's own fullscreen button throws an error, use Subflix fullscreen or open the player in its own tab.
Playback mode
Playback continues in a dedicated viewer designed to keep the watch experience simple and steady.
Cast And Share
These providers run inside an external iframe, so the most reliable casting flow is to open the player in its own tab and use your browser or device cast controls there.
Preparing your player
MoviesAPI is loading in the watch shell. If it takes too long, Subflix will offer another server.
