As the Hubble tension continues to bubble, can an extra phase of expansion set right our understanding of the Universe’s history?
A joint European and Japanese mission to Mercury sets off to answer questions about the planet’s geology, magnetosphere, and to try and prove Einstein wrong.
Is string theory compatible with observational data? Today’s paper looks at how avoiding the swampland of unsuccessful string theories can mean violating reliable constraints on cosmological quantities.
Venturing off to your first conference can be a very daunting experience, but they’re also the best way of meeting people in your field and getting inspired by new ideas. To make the first plunge a little easier, here’s 10 top tips on how to survive (and enjoy!) your first conference.
