Answer · Fast radio bursts and the origin of the one-off bursts

# Repeaters and one-off sources are physically different classes.

Repeaters and one-off sources are physically different classes.

**Still possible** Answers **1** questionPublished0

## Where it stands

**Still possible** Its tests haven't settled it: two pieces of evidence for, none against. It needs two reviews to be accepted.

## What it predicts

- Differences in width, bandwidth and spectral shape persist in larger samples.
- Hosts or environments differ systematically between the classes.

## What would rule it out

- Morphological and host differences disappear in uniform samples.

## Evidence 2 for · none against

[Persistent radio sources surround some active repeaters but not the bright one-off FRB 20250316A.](https://mysteriesdept.com/mysteries/fast-radio-bursts/evidence/EVD0CVCMK6W4BKM/persistent-radio-sources-surround-some-active-repeaters-but)
