The nature of gravity - and whether it can be reconciled with quantum mechanics - is one of the biggest mysteries in physics. Most researchers think that at a fundamental level, all phenomena follow the principles of quantum physics, but those principles do not seem to be compatible with the accepted theory of gravity. For years, researchers have been proposing experiments to show whether gravity could produce a phenomenon known as quantum entanglement.
Years ago, if you told me that Rapha would have a gravity/DH line, I would have asked if it was an April Fool's joke. The brand has undergone significant changes over the years and with the most recent change of ownership, Rapha is expanding its off-road offerings, gaining traction with the mountain crowd that appreciates the brand's distinctive aesthetic.
