Unsolved Mysteries In Physics | Fast Radio Bursts

South Wales and then you also have these huge big arrays of smaller dishes as well like the VLA in New Mexico so huge variation in terms of radio telescopes but radio astronomy is really cool with the things that you can detect so we find these FRBS distributed completely across the sky it’s not like they’re focused.

In the Milky Way planes we know that they’re not coming from our own galaxy there’s Imus Cassatt across the sky although they are biased to the fact.

That we have radio dishes that are sensitive to these in specific locations on earth so you kind of bias.

By whatever latitude that those telescope’s are at rebuffing that they’re pretty much well distributed the fact that they’re fast radio bursts like the fact that they’re milliseconds suggests that the object that the burst is coming from is actually quite small so it’s like a kilometers across we’re talking like the end life of a star maybe like a neutron star perhaps or a magnetar which is a really.

High magnetic field neutron star or perhaps a pulsar which is a spinning neutron star something like that which is like incredibly small but incredibly dense that might be able to give off these these fast bursts but the fact that we.

Know that they’re also coming from outside galaxies and they’re incredibly bright incredibly short-lived mean something so energetic like it’s.

80 times the output from the Sun in a year in a single radio burst so there has been lots of theories proposed perhaps it’s from merging black holes or neutron stars just like the gravitational wave discovering a couple years ago perhaps they have a connection with the gamma-ray bursts that we’ve been setting as well perhaps it’s an incredibly.

Energetic supernova in itself or I think my favorite figure just because it has the best name a Blitzer so a Blitzer is actually a completely theoretical.

Object we don’t know if this actually happens or not people think that perhaps a rapidly spinning neutron star bits accreting material gets to a point where it’s so dense.

That it could collapse into a black hole and perhaps that collapse is what gives off these fast radio bursts so back in 2010 the Parkes radio dish in Australia they thought they’d discovered a new type the bath Barbie and they dubbed these hairy Tom’s.

And they thought about 16 of them they were very very similar to fr bees they were these short pulses of radio waves but they quickly discovered that actually they were terrestrial.
In origin they were coming from Earth but the fact that they.

Similar to the fr bees that we were discovering in space was weird and.

It’s with people a long time to figure out what was actually causing this when they did they published what is possibly one of my.
Favorite actually papers of all time this is what.

They ended up finding was that staff at the observatory who were on their break when they were heating up their food if they opened the microwave door for the time and had run out then a tiny amount of a radio signal would manage.

To escape from the microwave and it would look just like an FRB from space except it was from Earth and this explained all.
