What do we think the universe is quantum? What if the universe was not quantized?

Classical mechanics was doing just fine after Isaac Newton reduced nearly all mechanical phenomena to a single powerful equation:...

Ask 10 physicists what a particle is: you'll get 10 different answers. Quantum mechanics showed via the Schrodinger equation, that quantum objects are not particles but waves smeared out in space, until the moment...

Many thanks and shout-out to David Tong's lecture on Quantum Fields for inspiring this video. I highly recommend his free lecture series. In my opinion, he and Richard Feynman are two of the best educators...

SUMMARY:

Quantum field theory or QFT is the basis of the best theory we have in physics today to explain nearly everything, called the Standard Model of particle physics. What is Quantum Field theory? Why is it...

SUMMARY:

How is string theory related to quantum field theory? Quantum field theory (QFT) is a mathemat
ical
framework that is close to a theory of everything. It describes nearly all particles and forces...

Quantum theory solved many problems with classical theory - the photoelectric effect solved by Einstein, atomic model solved by Niels Bohr. But quantum theory had a high price - determinism. it introduced...

SUMMARY:

Why Everything in the universe is a spring (kind of). Why everything is a spring. Classical springs like you might have in your mattress have a harmonic oscillation. And this behavior has a quantum...

Was the Universe Designed? Exploring the effect Dark Energy has on our Universe.

Can a close look at the universe give us solutions to problems too difficult even for a planet-sized computer to solve? Physicist Stephen Jordan considers this question and more in our latest video.

We've gone through some of the main advancements in modern physics, which brings us to the here and now! What are physicists currently working on? One huge area of interest is developing a quantum field theory for the gravitational...

Electromagnetic force down, three more forces to go! Which one is next? Why it's the strong nuclear force, famous for keeping atomic nuclei together. What kind of particles will be involved in this quantum field theory? Let's find out.

How is it possible that you can't see 95% of the universe? The edge of our milky way defies known physics, so physicists are using the LHC at CERN to search for Dark Matter. Dianna Cowern from Physics Girl visited CERN and spoke to...

A particle physics take on Drake's "Started From the Bottom," explaining the Higgs-to-bottom-quark decay pathway and shot on site at the Large Hadron Collider

In our study of physics, we have become aware of four forces, and the fields that mediate them. Once we got deep into quantum theory, we started to realize that these forces are not mediated by fields at all, but rather by quanta. That's...
