The Large Hadron Collider (LHC), the world’s biggest particle smasher, stands a good chance of discovering the elusive particle or particles, known to scientists as dark matter, that make up five-sixths of the mass of the universe, researchers say.
The sooner-than-expected discovery of gravitational waves, announced in February, has given a new impetus to scientists in the field, who are now working to make sense of what it means not only for their research but also for our understanding of Einstein’s theory of general relativity.
At the extremes of mass, energy, gravity and space-time – black holes still present a mystery for scientists, yet the key to finding a way forward is reconciling gravity, described by Albert Einstein’s general relativity, and the behaviour of subatomic particles modelled using so-called quantum theory.
Sending astronauts to Mars poses several large challenges, among them a long journey filled with life-threatening radiation from cosmic ray exposure and solar flares. Not to mention the fact that we haven’t yet worked out how to get them back again.
There could have been life under the surface of Mars, according to Prof. Jan Woerner, Director General of the European Space Agency (ESA), which in March is launching its ExoMars mission to find out.
Detailed biomass maps will enable developing countries to better access climate funds.
