In his essay “The Unreasonable Effectiveness of Mathematics”, the physicist Eugine Wigner said that “the enormous usefulness of mathematics in the natural sciences is something bordering on the mysterious”. This statement was inspired by...

Life exists in our universe. There we go - one hopefully uncontroversial statement. Therefore our universe is capable of producing and supporting life. How am I going? Two for two? Let’s try for three: therefore there are countless...

Many Worlds interpretation of quantum mechanics proposes that every time a quantum event gets decided, the universe splits so that every possible outcome really does occur. But where exactly are those worlds, and can we ever see them?

In the Many Worlds interpretation of quantum mechanics, the universal wavefunction is the reality, encompassing all possible histories and futures and all exist. But we are only sensitive to a slice of the wavefunction corresponding to...

The True Science of Parallel Universes

Just a few days before he died, Stephen Hawking submitted one last research paper using string theory math to talk about the multiverse.

We think of space as a silent place. But physicist Janna Levin says the universe has a soundtrack -- a sonic composition that records some of the most dramatic events in outer space. (Black holes, for instance, bang on spacetime like a...

Parallel 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...

The Milky way galaxy is composed of up to 400 billion stars, and at least that many planets. Our star, the sun is one of those billions, about a third to halfway out from the galactic center....

Part 2 in our Multiverse series.

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

Multiverse theory suggests that our universe, which consists of billions and billions of planets, stars and galaxies and extends out tens of billions of light-years, may not be the only universe that exists. There could be another...

Celebrated physicists Nobel Laureate Tony Leggett (University of Illinois), Freeman Dyson (Institute for Advanced Study), Paul Steinhardt (Princeton University), Michael Gordin (Princeton University) share their intriguing perspectives...

Princeton University physicist Paul Steinhardt relates how many top cosmologists simply ignore the problems with cosmic inflation.

Physicist Paul Steinhardt, Princeton University, describes how many practicing scientists confidently assume that the unsolved problems of a theory will eventually be rectified rather than embracing the uncomfortable prospect of starting...

Princeton University physicist Paul Steinhardt describes how many cosmologists simply ignore one of the most pronounced problems with the theory of cosmic inflation.

Physicist Paul Steinhardt, Princeton University, describes how many advocates of inflationary cosmology now believe that no observational evidence could possibly invalidate their theory, leading Paul to conclude that philosophy should be...

Quantum physicist Artur Ekert (Oxford and NUS) describes how Einstein's view of reality for quantum theory can be preserved in the many-worlds interpretation.

Princeton University cosmologist Paul Steinhardt describes how many of his fellow physicists could benefit from more rigorous philosophical understanding.

Urban legend holds that in 1954 a man arrived in Tokyo International Airport. He hands over his passport, filled with stamps from all the countries he’s visited, but the passport was issued… in Taured. Security pulls him aside and asks...

Multiverse theory suggests that our universe, which consists of billions and billions of planets, stars and galaxies and extends out tens of billions of light-years, may not be the only universe that exists. There could be another...

New research simulating the effects of dark energy on star formation speculates that alien life may exist in another universe.

What happened before the big bang? How can something come from nothing? We've challenged a physicist to explain the origins of our universe in one elevator ride. Good luck Dr Julian Berengut, from University of NSW.

Rasty Salah from Freiburg in Germany would like to know if there is any proof of a multiverse, and would the laws of physics there be the same?"



​ESA physicist Paul McNamara gave his answer: "So it’s a very good...
