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.

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.

In just a few seconds, a gamma-ray burst can release more energy than the Sun will produce in its entire lifetime. The universe is home to cataclysmic events that dwarf human-made energy sources, leaving many to wonder, "what releases the greatest amount of energy?"

An estimated 99% of the calcium in the human body is stored in bones and teeth. But beyond our bodies, where does calcium naturally come from? This versatile and essential element has origins that span the cosmos, the Earth's crust, and the natural food cycle that sustains all life.
