Can we gravitationally hitch-hike out of the solar system? Do we live in a multiverse? What is time? Plus Dr Robert Massey is on hand with his top star-gazing tips.

Your device’s IP address and user agent is used to help calculate this figure. Acast is IAB v2 certified. Here is more detail about podcast statistics.
Tracking and attribution: Acast or its partners may connect the fact you listened to this podcast to an action elsewhere on the internet. For example - it may spot a device that downloaded an episode of The Supermassive Podcast later visited the website of an advertiser; or it may track that a device that listened to The Supermassive Podcast also listened to a different show. This form of attribution is used to measure advertising effectiveness.
Dynamic content insertion: Acast may use limited data that they know about you - the device you’re using, the approximate location you’re in, or other data that can be derived from this, like the current weather forecast for your area - to change parts of the audio. The Supermassive Podcast may do this for advertising or for other forms of content, like news stories.
