In a presentation that can only be described as epic, comedian Charles Fleischer delivers a hysterical send-up of a time-honored TED theme: the map. Geometry, numbers, charts and stamp art also factor in (somehow), as he weaves together...

Cosmologist Sean Carroll attacks -- in an entertaining and thought-provoking tour through the nature of time and the universe -- a deceptively simple question: Why does time exist at all? The potential answers point to a surprising view...

The biggest surprise of discovering the Higgs boson? That there were no surprises. Gian Giudice talks us through a problem in theoretical physics: what if the Higgs field exists in an ultra-dense state that could mean the collapse of all...

Hank Green presides over this battle between the other two hosts of Eons. They know dinosaurs, but how much do they really know about industrial grease?

"Rock-star physicist" Brian Cox talks about his work on the Large Hadron Collider at CERN. Discussing the biggest of big science in an engaging, accessible way, Cox brings us along on a tour of the massive project.

Why is there something rather than nothing? Why does so much interesting stuff exist in the universe? Particle physicist Harry Cliff works on the Large Hadron Collider at CERN, and he has some potentially bad news for people who seek...

Over the last few years astronomers have been doing more and more research based on string theory, and thanks to modern telescopes the results are... less than encouraging

Why strings? What are they made of? How did physicists even come up with this bizarre idea? And what's all this nonsense of extra dimensions?

Music is everywhere, and it is in everything, says musician, student and TeD-ed Clubs star Anika Paulson. Guitar in hand, she plays through the beats of her life in an exploration of how music connects us and makes us what we are.

What is reality? What is the standard model trying to tell us? Are we living in the 11 dimensions of string theory?



The holy grail of physics is a theory of everything. It may show the...

What came before the Big Bang? what happened before the big bang? Since time is thought to have started at the big bang, asking what happened "before" is like asking what is North of the North pole? It may have no...

The term, “Mandela effect” was coined in 2009 by Fiona Broome, a “paranormal consultant.” She published a website where she described remembering Nelson Mandela, who had been an imprisoned leader of the...

In a classical universe, if we knew all the positions and velocities for all particles, we could predict the future and the past. Quantum mechanics is not like this. It shows that reality is not deterministic but is...

What is string theory? When string theory is simplified - it can answer the question "Why do we exist?" First you must accept that there are two worlds we live in - the world of the large, the world we can see, which...

The gauge bosons of the standard model of particle physics are responsible for 3 of the 4 known forces in the universe. A force is conferred is through the exchange of virtual bosons. So for example in...

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...

Is a theory of everything really possible? What makes us think it even exists? If we look at historical precedent, we can see that we have united seemingly completely unrelated forces and particles to a...

Why to neutrons exist? You may say, this is a silly question. But the problem is that we know that free neutrons are unstable. This means that if you isolate a neutron by itself, after about 15 minutes, it will...

How the Planck scale is derived from the most important fundamental constants in physics. This is where our physics ends. If you wanted to simulate the universe in a computer, you would need to enter...

Does a final theory exist that can end our reductionist probing into ever shorter distances? Or is there no end to reductionism? There should be an end point because as the object of our measurement gets small...

E8 Lie group and E8 Lattice has sometimes been called the most beautiful mathematical structure in the world. Is it the theory of everything or the true nature of reality? It even has an entire research...

SUMMARY

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...

In part two of our series on Theory of Everything, we explain particle physics using string theory.

Celebrated scientist and writer Freeman Dyson, Institute for Advanced Study, describes how, due to reinforcing economic and sociological reasons, far too many people are now doing research in superstring theory.
