Universe Today revisits the singularity problem and why general relativity fails at the universe's apparent beginning.
The article highlights the Wheeler-DeWitt equation as an early attempt to treat the entire universe as a quantum object.
It sets up Stephen Hawking's later argument that the question of a beginning may itself break down under quantum cosmology.

An 8.19-millisecond pulsar candidate has been detected near the supermassive black hole Sagittarius A*
If confirmed, it would enable the most precise tests of Einstein's general relativity ever conducted
The discovery emerged from the Breakthrough Listen Galactic Center Survey, one of the most sensitive radio searches of its kind
The object may be a magnetar with a magnetic field 1,000 times stronger than an ordinary pulsar
All observational data has been made publicly available for independent verification by global research teams

A millisecond pulsar candidate spinning every 8.19 milliseconds was detected near the Milky Way's supermassive black hole
The discovery emerged from the Breakthrough Listen Galactic Center Survey using the Green Bank Telescope
If confirmed, it could serve as a precision tool for testing Einstein's general relativity under extreme gravity
Follow-up observations are underway, with all data released publicly for independent verification
Very few pulsars have been found near Sagittarius A* despite models predicting thousands should exist
