birth of the universe

“The evolution of the world can be compared to a display of fireworks that has just ended; a few red whisps, ashes and smoke” Georges Lemaître Meet the experts Name: Richard Davis Role: Professor Head of technology at Jodrell Bank. Led his institution’s involvement in the Planck mission. Name: David Evans Role: Professor Leads the University of Birmingham team on ALICE at CERN’s Large Hadron Collider. Name: Dan Coe Role: Astronomer Staff astronomer at the STScI, studying galaxy clusters, gravitational lensing and dark matter. The universe almost seems to have come out of nowhere: a concoction of high temperatures and a thick gloop of exotic particles, which would go into an overdrive of expansion through several phases of varying conditions, to create the universe as we see it today, some 13.8 billion years later. The Big Bang, creator of time and…

how it all began

1. The Big Bang The event that is said to have created time and space is thought to have occurred some 13.8 billion years ago. Here the universe was infinitely hot and dense before cooling and inflating. 2. Quark soup One trillionth of a second after the Big Bang, the weak and electromagnetic forces separated, leaving us with the four major forces that we know today – strong, weak, electromagnetic and gravity. Quarks, leptons and their antimatter particles were also whizzing around and colliding. 3. Big freeze out One hundred seconds after the Big Bang, the temperature dropped to the point where protons and neutrons could stick together without being torn apart. Conditions were ripe for hydrogen to form. 4. Parting company After some 380,000 years, the opaque soup began to clear and, since the temperature of…

seeing the start

And then there was light. That’s pretty much how our universe sprang into existence; as a point that contained everything and continued to expand through to today, building the first stars and galaxies and stretching light years of distance between them. Despite its name, the Big Bang wasn’t some kind of explosion that spat out matter, energy, time and space. It is imagined almost like a balloon that continues to stretch, originally holding an incredibly hot and dense primordial soup that cooled and thinned out over the space of millions to billions of years. As ever, such an event has opened up a whole deluge of questions. And the only way to attempt to look back in time is to lift missions off the ground to seek answers; providing us with…

how it will end

Closed universe The density of the universe is more than five atoms of hydrogen per cubic metre. There’s no repulsive effect of dark energy and gravity eventually halts the universe’s expansion. With contraction, all the matter in the universe collapses to a point – the Big Crunch Open universe If space is open and curved, the universe will continue to expand forever. Dark energy will help to drive the expansion. The result? Heat death, the Big Freeze or the Big Rip is imminent. Here the universe’s density is less than the critical density. Flat universe With no dark energy, a flat universe will expand forever at a decelerating rate. With dark energy the expansion initially slows thanks to gravity, then speeds up. The universe’s ultimate fate is the same as if it were open. Density…

re-creating the big bang

Tucked away in the highly populated city of Geneva in Switzerland, the particle-smashing Large Hadron Collider (LHC) – built by the European Organisation for Nuclear Research, which is more commonly known as CERN – has been hard at work accelerating particles to breakneck speeds close to the speed of light. The aim? To attempt to re-create what the early universe might have been like just a few minutes after it was born. The particle accelerator, which houses two detectors dedicated to pinpointing the moments during our universe’s growth (LHCb and ALICE), works as a Big Bang-making machine. The differences are that this ‘explosion’ is on a much smaller scale and scientists have a bit more control over it. For ALICE, the aim of the game is to smash particles of lead…

missing pieces

1. Disappearing antimatter In the beginning, there were equal amounts of matter and antimatter – two materials that, when they come together, annihilate each other. Why, then, does our universe now contain mostly matter? 2. The horizon problem Are the widely separated regions of the sky too far apart to communicate with one another? If they’re unable to communicate, scientists are unsure how they know to have the same temperature. 3. The flatness problem Evidence suggests that the present universe is pretty much flat. Experts think that its current form is a very unlikely result of the universe’s evolution from the Big Bang. 4. Galaxy formation Random bumps in the expanding universe may not be enough to form galaxies. In a rapidly expanding universe, gravitational attraction loses the fight and is too slow for these structures to…
