Lawrence Krauss says that our universe may be about to end

At a recent after-dinner talk in Melbourne Australia attended by a group of Ex-Christadelphians and hosted by Victorian Skeptics, Theoretical Physicist, Cosmologist, best-selling author and science and public policy advocate Professor Lawrence Krauss made the startling claim that our universe could fall out of existence without warning, at any time.

He also proposed that in the far distant reaches of our universe, new, much younger universes are likely being spawned off our own universe. These new universes would not end when our own disintegrates, but they also would one day fall out of existence, like bubbles popping when they age.

Lawrence Maxwell Krauss is an American theoretical physicist and cosmologist who is Foundation Professor of the School of Earth and Space Exploration at Arizona State University and director of its Origins Project.

His latest book A Universe from Nothing explained how our universe could have spontaneously self-generated from literally nothing. Now he is suggesting that it could return to that same nothing in the smallest fraction of a second. This makes nonsense of the Christadelphians' claim that they will be rewarded with eternal life. Not only is our universe not eternal, but it might fall apart and disappear far sooner than we expect; exposing the Christadelphian promise of salvation as a transitory, superstitious human delusion.

See the snake-like changes in the polarisation
of gravity waves from the Big Bang which
allows Cosmologists to "see" what happened
at the start of our universe
The talk, entitled An Update on Recent Developments in Cosmology, explained how during the past few weeks and months, scientists have been using the polarization of gravity waves generated by the Big Bang and subsequent inflation, to peer back in time before the previous limit of 380,000 years after the creation of our universe. This previous cosmic dead end is known as the epoch of recombination.

Before this time the universe was still too hot for electrons and protons to pair up and form the most basic atom, hydrogen. Unbound electrons scatter light. So, until those first hydrogen atoms came onto the scene, scientists think, the cosmos was an opaque soup of energy. Only afterward did the universe became transparent to light—light that was free to stream into our telescopes. The relic light from this recombination event is known as the cosmic microwave background radiation. We observe it as a diffuse, essentially featureless, uniform glow from all over the sky, and it was most recently charted by the European Space Agency's Planck spacecraft.

However, using the new gravity wave polarization technique, cosmologists are now able to "see" the original Big Bang take place. For the first time they can peer through the opaqueness of the first 380,000 years of our universe back to the time when the four forces of the universe (the Weak Force, the Strong Force, Electromagnetism and Gravity) were combined into a single force in the raging hot, dense plasma following the Big Bang.

What they see indicates the presence of new, previously undiscovered particles that must still exist today and the hunt has commenced to find them in particle colliders.

However the worrying part of these new discoveries is that it is becoming increasingly obvious that our universe as we know it is merely a "phase transition" in its cooling from the original extremes of heat. That makes it rather like steam condensing into water, or water solidifying into ice.

The Higgs Field assigns mass to all particles
except photons. When it ceases to exist, so will we!
The recent discovery of the Higgs particle, which fills our universe with an ever present field that gives mass to all other particles (except photons), could therefore be only a condensatory, transient phase in our universe; rather like an early morning fog can be dispelled by sunshine. In the case of the Higgs field, it would be the cooling of the universe, not heating, that would cause the Higgs "condensation" to fall out of existence.

But if this were to happen, all of the particles in our universe would cease to have mass assigned to them and the entire universe would disintegrate in a moment of time.  

This idea postulates an entirely new concept of the universe. Instead of slowly cooling over hundreds of trillions of years, many different universes would be bubbling into existence and quickly popping out of existence like a glass full of freshly poured soda produces bubbles. "Quickly" would still mean several billion years.  

So the message of the talk was simple: Our universe is NOT "fine-tuned for life." - It is tuned for death. There is no known reason why the Higgs Field should not fall out of existence in the next second and take all of life, the galaxies and everything else in the universe with it. Don't be fooled by primitive human superstition promising endless life. It's not going to happen. Be sceptical about ridiculous claims such as those made by the Christadelphians. We are not going to be raised from the dead. We are heading for nothingness.

Editor's Note: Some of the contents of the talk are currently embargoed from publication because Lawrence has prior commitments in releasing the material. An edited version of the video of the talk will be uploaded to this article soon when that embargo is lifted.
