The ultimate nothing that could be the source of everything

What is the nature of nothing? Is there such a thing as absolutely nothing, or is there always something, even if it is invisible or incomprehensible to us? One of the most intriguing concepts in modern physics is that of quantum foam, also known as spacetime foam. This is the idea that at the smallest possible scales the fabric of space and time is not smooth and continuous, but rather bubbles and fluctuates with quantum fluctuations. These fluctuations create tiny virtual particles that pop in and out of existence, creating a foam-like structure that permeates the entire universe. Quantum foam…
