Question

Given the Heisenberg uncertainty principle, is it possible to create particle–antiparticle pairs that exist for extremely short periods of time before annihilating? Does this mean that empty space is really empty?

Short answer

Yes, it is possible.

The empty space truly isn’t all that empty space.

Step-by-step solution

Heisenberg Uncertainty Principle

Yes, it is possible and has been experimentally confirmed throughout the 20th century. It seems to give the impression, as written in the book, that the empty space truly isn’t all that empty space after all, provided that quantum mechanical processes like the generation of virtual particles are a common occurrence in astrophysical settings.

Conclusion

Hence, the empty space truly isn’t all that empty space.
