A cartoon illustrates results from the MICROSCOPE satellite mission, which has measured with astronomical sensitivity the falling rate of different objects under gravity.
The gravitational fields of black holes and other compact objects are strong enough to wrest pairs of particles and antiparticles out of the vacuum and into existence, causing the objects to decay. Read More »
A new search for an interaction between a particle’s intrinsic spin and Earth’s gravitational field probes physics in the regime where quantum theory meets gravity. Read More »
A space-based observatory will detect gravitational waves from so many different types of sources at once that a global approach will be needed to crunch the data. Read More »
