Sediments accumulate on deep ocean floors at a rate of a few centimetres every thousand years. The study of this – called stratigraphy – involves drilling vertically down into the sea bed to extract a sample core which gives a picture of continually changing life, environment and climate.
Dr. Jan Zalasiewicz, of the University of Leicester’s Department of Geology, together with Professor Paul Pearson of Cardiff University and colleagues at the Stratigraphy Commission of the Geological Society of London, propose that exhibiting a core will dramatically illustrate how brief human history has been. A continuous core going back 64 million years – to the time of the dinosaurs - would be 1.5km long.
Writing in the journal ‘Geoscientist’, he said: “On this scale, the last 10,000 years in which civilization developed is about 30cm thick… and the time since the Industrial Revolution is represented by just a few millimetres of sediment.”
Key events could be marked, such as the evolution of humans and also, more importantly, the huge lengths of time over which the Earth has endured, and recovered from previous climactic upheavals such as ice ages.
He continues: “At the base of the core a signpost would point to the formation of the Earth, 100km away, and the origin of the universe at 300km.”
The exhibition, if ever realised, would be comparable in scale to the UK’s National Space Centre, the brainchild of the University of Leicester, or the Eden Project.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
