A wobble from Mars could be sign of dark matter

MIT physicists propose that microscopic primordial black holes, potentially a major source of dark matter, could pass through our solar system about once per decade. These flybys might cause a detectable wobble in Mars' orbit, shifting it by about a meter within a few years. This effect could be observed using current technology, potentially supporting the idea that primordial black holes are a significant component of dark matter.

The researchers simulated various scenarios of asteroid-mass black holes passing through the solar system at different angles and speeds. They found that close encounters with Mars would be the most likely to produce observable effects. If such a wobble is detected in the coming decades, it could provide evidence for the existence of primordial black holes and their role in dark matter composition.
