The Audacious Plan to Launch a Solar-Powered Rocket Into Interstellar Space

Ars Technica glimpsed a possible future at the Johns Hopkins University Applied Physics Laboratory: a solar simulator “that can shine with the intensity of 20 Suns…” “They think it could be the key to interstellar exploration.” “It’s really easy for someone to dismiss the idea and say, ‘On the back of an envelope, it looks great, but if you actually build…

To Explain Away Dark Matter, Gravity Would Have To Be Really Weird

To discard the theory of dark matter, “you’ll need to replace it with something even more bizarre: a force of gravity that, at some distances, pulls massive objects together and, at other distances, pushes them apart.” That’s how Science magazine describes a new study, adding that “The analysis underscores how hard it is to explain away dark matter” — even though…
