Exploring the possibilities of Earth's materials being used in the formation of new planets, black hole spaghettification and object placement in space, orbit and space management around L2 point, and the movements of a space telescope and the big bang theory.
Our belongings on Earth may be destroyed by the expanding sun or covered in lava, but the atoms from which our stuff is made may disperse in space and end up in new stars and planets.
Spaghettification occurs when an object gets stretched out due to the changing curvature of space around merging black holes, but it does not happen to event horizons. Objects sent to Lagrange points have large volumes of space to orbit around, minimizing the risk of blocking telescopes like the James Webb Space Telescope at L2.

The Fate of Earth and Our Stuff
In the future, the Earth may be swallowed by the expanding sun, causing most of our belongings to be destroyed. Even if the Earth isn't consumed, the surface will likely be covered in lava, making it unrecognizable. However, the atoms from which our stuff is made may disperse in space, potentially ending up in new stars and planets.
Spaghettification and Black Hole Mergers
Spaghettification occurs when an object, like a star, gets stretched out into a long chain of atoms due to the steep gravitational gradient of a black hole. However, spaghettification does not happen to event horizons, which are the boundaries of black holes. As two black holes merge, the curvature of space around them changes, causing their event horizons to reach out towards each other. While this can cause a stretching effect, it is not due to spaghettification.
Placing Objects at Lagrange Points in Space
Objects sent to Lagrange points, like L1 and L2, actually orbit around those points instead of staying stationary. The Lagrange points have a large volume of space to accommodate these orbits, similar in size to the moon's orbit around the Earth. Space agencies coordinate the placement of objects to avoid collisions, and missions are often moved away from these points at the end of their lives to minimize the chances of any collisions. So, the risk of blocking the view of telescopes like the James Webb Space Telescope at L2 is extremely unlikely.
From barbie dolls, to birds baths, what will happen to all the stuff we have made between now and the end of time? Could a large black hole spaghettify a small black hole? Could more satellites block JWST's view? And what came first, the Big Bang or Inflation?
It's time for another deep dive into The Supermassive Mailbox with Izzie Clarke, Dr Becky Smethurst and Dr Robert Massey.
