Dark matter could be almost anything. With little data other than how much total dark matter mass exists, we can’t decode much about what individual chunks of dark matter might be made of. I’ve talked before about Massive Compact Halo Objects (MACHOs) and Weakly Interacting Massive Particles (WIMPs), but these are just two possibilities. Other theorists have talked about Modified Newtonian Gravity (MNG), where gravity may work differently on the grand scale than it does on our small Earth scales. Or perhaps it’s something I haven’t seen before. Maybe what we call dark matter is just a large population of ancient black holes....
I am a big fan of John Oliver and his HBO show ‘Last Week Tonight.’ Last night the show covered a topic near and dear to me, the publication of science and how it is communicated to the layperson. He raises very important points about how scientists are motivated to produce exciting new research for grants and tenure, rather than replicating existing studies to prove or disprove them. He also talks about how science is portrayed in the media, and how studies are interpreted without context or fine details. We need science communicators. People who are scientifically literate and can communicate complex...
I feel like I’ve been covering a lot of stories on magnetic fields over the past few months. Fields around the Earth, the Sun, Mars, Jupiter’s Moons, and exoplanets are just some of the places in the universe where we are looking at magnetic field behaviour. The intention is to use our understanding of magnetism to figure out what is inside these worlds, and how they interact with their space environment. You would expect us to understand the Earth’s magnetic field and interior very well, after all, we are stuck here. But it turns out it’s very difficult to study the interior of...
