It has had many dissenters, however, including the British astronomer Sir Fred Hoyle, the Nobel laureate Hannes Alfven, and astronomers Geoffrey Burbidge and Halton Arp.

According to the Big Bang theory, some 10 to 20 billion years ago, all of the matter and energy of the universe was compressed into a cosmic egg, or plasma ball, consisting of sub-atomic particles and radiation.

The researchers collected roughly 70-metre core samples from the lake and painstakingly counted the layers to come up with a direct record stretching back 52,000 years.

Preserved leaves in the cores — “they look fresh as if they’ve fallen very recently”, Bronk Ramsey says — yielded 651 carbon dates that could be compared to the calendar dates of the sediment they were found in.

The universe consisted essentially of hydrogen gas.

Then somehow, we are told, the molecules of gas that were racing out at an enormous speed in a radial direction began to collapse in on themselves in local areas by gravitational attraction.

The problem, says Bronk Ramsey, is that tree rings provide a direct record that only goes as far back as about 14,000 years.

Various geologic, atmospheric and solar processes can influence atmospheric carbon-14 levels.

But that assumes that the amount of carbon-14 in the atmosphere was constant — any variation would speed up or slow down the clock.

The clock was initially calibrated by dating objects of known age such as Egyptian mummies and bread from Pompeii; work that won Willard Libby the 1960 Nobel Prize in Chemistry.

Carbon dating is used to work out the age of organic material — in effect, any living thing.

The technique hinges on carbon-14, a radioactive isotope of the element that, unlike other more stable forms of carbon, decays away at a steady rate.
