What is the Big Bagel Theory?

5 min read
First proposed by Howard Bloom, the Big Bagel Theory is a highly speculative cosmological model that suggests the universe has a toroidal, or doughnut-like, shape rather than the more commonly accepted flat geometry. This unconventional idea offers an alternative explanation for the universe's accelerating expansion, addressing some of the unknowns present in the standard Big Bang model.

Is energy density positive or negative?

4 min read
In most everyday classical physics, the energy density of objects and fields is always considered positive. However, at the quantum level, this simple rule is broken by phenomena like the Casimir effect, which demonstrates that certain regions of space can possess a negative energy density relative to the surrounding vacuum. This fascinating concept forces physicists to reconsider the fundamental nature of energy.
