Mysterious radiation could lead to less mysterious gravitation
A mysterious single blast of radio waves was observed in archived imagery data from 2001 detailing the portion of space containing the Small Magellanic Cloud; its cause: unknown. The burst may look insignificant at first, a single 5-millisecond blip during a 480-hour observation, but what makes astronomers excited is the fact that its location and wide dispersion indicate it must come not from the Cloud, but rather from very far away, about 3 billion light years from Earth; unfortunately, it’s impossible to pinpoint it to any galaxy or celestial object, making it harder to find out what caused it. However, Duncan Lorimer, an astrophysicist at West Virginia University in Morgantown and the National Radio Astronomy Observatory who led the team behind this discovery, says events like this could be detected a couple hundred times per day, if only they were looked for with the right equipment.
Why is a finding like this important? One hypothesis is these waves were emitted when two neutron stars collided or during the death of a black hole, meaning their observation could help find proof of the existence of the gravitational waves predicted by Einstein’s theory of relativity (which theoretically should be emitted by titanic events like those) but were never directly observed. In turn, these could teach us something more about black holes and ultimately about the inner workings and origin of the Universe — surely no small result for a 5-millisecond blip and worthy of ending up in my gallery of Mysterious Mysteries.

This post was going to appear days ago but for various reason it’s been delayed. However, I thought I’d still publish it even if late, and say a few words especially because these issues have been discussed at length lately.

What a nice time to be outside and play. The sun is shining, the grasses are golden and the sky is gray and thick with the smoke and ashes from wildfires that have been burning for days up on the mountains. There’s no wind in sight, therefore the smoke adds up to the usual daily amount of pollution and just sits quietly where it is, generously offering its healthy gifts to our unsuspecting and eager-to-breathe lungs. People are advised to stay indoors if they can, while, after the first few critical days, television news programs happily celebrate the improvement of the air quality from a rusty “Unhealthy” to a luminous “Moderate”, champion knight of all our dreams of relieved bronchi, showing that, notwithstanding our negative skepticism, once again we managed to return to the dose of aerial poisons we’re used to. Hold your breath if you really want to persist in having any instinct of self-preservation — the utility of breathing is overrated, in any case.
