Does a Copy of You Exist in a Multiverse?
New ReviewSUMMARY The idea that there may be different versions of you comes from the concept of multiverses. There are many types of multiverses in physics. But at least two multiverse concepts based on generally accepted and observationally...

Could Time Be an Illusion?
New ReviewSUMMARY What if time is not real, but an illusion? Isaac Newton believed time was absolute and ticked at the same rate for everyone, everywhere. But Albert Einstein shattered that view with the theory of relativity. He showed that time...

How the First Atom Formed After the Big Bang
New ReviewSummary: Where did the first atom come from? The short answer is the big bang. In the early universe there was an immense amount of energy, The energy condensed, atoms formed. But there's a lot more that happened, which will be explained...

Are Photons and Electrons Particles or Waves? Understanding Duality
New ReviewSummary: By the end of 1905, we had two big new equations in physics. Max Planck’s, Energy equals Planck’s constant times the frequency, and Einstein’s Energy equals the mass times the speed of light squared. A young physicist, Louis...

How the Delayed Choice Quantum Eraser Works
New ReviewThe original paper by the authors who first performed the Delayed Choice Quantum Eraser implied retro causality. But retro causality is true only if you assume a classical way of thinking. But that's not the way quantum mechanics works.

Anti-Gravity: the Force that's Tearing Space Apart
New ReviewSUMMARY What if gravity repelled instead of attracted? Repulsive gravity may have shaped the entire history of our universe. For centuries gravity was defined by Isaac Newton’s Law of Universal Gravitation which said, “every object in...

Quantum Theory, Parallel Universes, and Quantum Immortality
New ReviewParallel universes are not a theory, but deductions from the "Many Worlds" interpretation of quantum mechanics. And there is at least on other theory that predicts not alternate universes but parallel universes where the universes are...

Is Quantum Tunneling Essential to Life and the Universe?
New ReviewWhat is this mysterious quantum tunneling effect, where does it come from? And why is it one of the most important phenomena in physics? Quantum mechanics shows that quantum objects have a wave-particle duality. What we think of as an...

An Impossible Information Paradox in Black Holes Seems to Break Physics
New ReviewSUMMARY In 1976, Stephen Hawing proposed that Black Holes, do something impossible according to the laws of quantum mechanics. They destroy information. This is a paradox because information should be conserved in the universe. If it is...

Principal Quantum Number: The Key to Electron Shells
The principal quantum number (𝑛) is a fundamental parameter in quantum mechanics that determines the size and energy level of an electron's orbit within an atom. It is a positive integer that represents the main energy level or shell in...

Negative Energy: Understanding Hydrogen's Electron
In a hydrogen atom, the electron is bound to the nucleus, so its energy is negative. This shows that it is in a bound state. When there is negative energy, it means that the electron is stable. It is inside the atom because its negative...

Heisenberg's Uncertainty principle : The Limits of Precision
Werner Heisenberg proposed Heisenberg's Uncertainty Principle in 1927, which states that measuring a particle's momentum and position at the same time with accuracy is not possible. One can know a property less precisely the more...

Heisenberg's Thought Experiment: Exploring Uncertainty
The Uncertainty Principle is demonstrated by Heisenberg's thought experiment, which demonstrates that increasing uncertainty in a particle's momentum results from precisely measuring its position, such as through a narrow slit, and vice...

De Broglie's Equation: Wave-Particle Duality
De Broglie's equation, formulated by Louis de Broglie in 1924, introduces the concept of wave-particle duality, suggesting that all matter exhibits both wave-like and particle-like properties. The equation is expressed as λ=h/p; λ is...
