- 1Could a Quantum Bubble Destroy the Universe? Probably Not▼A Quantum Bubble Could End Reality as We Know It. Here's Why It (Probably) Won't https://gizmodo.com/a-quantum-bubble-co
Physicists are revisiting the idea of vacuum decay, in which a bubble of 'true vacuum' could expand at light speed and rewrite the laws of physics, erasing everything. The reassurance is that such a bubble is extremely unlikely to form near us, and if one existed elsewhere it would already be here, so there is nothing to worry about in practice.
