The model of our universe as expanding at an accelerated rate has given rise to theoretical constructs such as dark energy and dark matter, which scientists believe could make up 95% of the universe. In September, Horizon takes a deeper look at what we really know about the expanding universe. We speak to Prof. Subir Sarkar, who believes that the Nobel-winning discovery that universe expansion acceleration could be a fluke, and the scientists who are trying to answer the question by allowing us to better measure the expansion rate. We also look at the significance of accurately measuring gravity in deep space, and what dark matter haloes can tell us about the existence of dark energy.
New efforts to figure out just how fast the universe has expanded since the Big Bang, a speed known as the Hubble constant, could upend current theories of physics, according to some scientists.
The most mysterious phenomenon in cosmology – dark energy – may not exist at all, according to Professor Subir Sarkar, head of the particle theory group at the University of Oxford in the UK.
The next decade sees Europe facing some urgent challenges: climate change, biodiversity loss and feeding a growing population, to name but a few. At the same time, technology is developing apace, presenting both opportunities for novel solutions and worries about how to ensure it’s used for good. In September, as plans for the EU’s next research funding programme start to crystallise, we take a look at some of the pressing issues facing Europe and how the next research agenda should be designed to best serve people and planet. We will also be covering the EU’s Research and Innovation Days event at the end of the month, where policymakers, academics, business people and civil society organisations will gather to finalise priorities for Horizon Europe, the EU’s €100 billion research programme which runs from 2021 to 2027.
In August, Horizon takes a look at the quest to make Europe’s cities environmentally sustainable, while also ensuring a healthy and prosperous population. We speak to geographer Professor Harriet Bulkeley on why cities have such an important role in fighting climate change, what it means for a city to be sustainable and the big challenges that lie ahead. We look at the construction of zero-energy housing, homing in on the case of Nottingham, UK, and find out how scientists are putting nature back into the old Spanish capital of Valladolid. We also talk to the city officials breathing new life into historical buildings in Bologna, Italy, and learn how urban planners and architects are taking emotional feedback into account when designing new public spaces and homes.
More than two decades ago, Professor Andrew Oswald worked at the London School of Economics, UK, when he organised what he says was the world’s first conference on the economics of happiness. He put up posters, invited speakers, and waited for the crowds to come.
Alternative measures of a country’s development could help build more equal and sustainable societies.
We asked three experts about what to expect from the next decade of cancer research.
Jean-Eric Paquet tells Horizon how a new annual event - Research & Innovation Days - aims to shape European research over the next 8 years.
