Jakarta, CNBC Indonesia – The hottest place in the universe is not the Sun. But there is a black hole that is reported to have a much hotter temperature than the center of the Solar System.

Named Quasar 3C273, the black hole has a core temperature of more than 10 trillion degrees Celsius. For comparison, the surface temperature of the Sun is ‘only’ 5,500 degrees Celsius.

The object is 2.4 billion light years from Earth. “I think the answer is very close to massive black holes, especially accretion, which means they gobble up gas,” said postdoctoral fellow at the Black Hole Initiative, Daniel Palumbo, quoted from Live ScienceThursday (24/8/2023).

Quasar 3C273 has the same characteristics as other black holes. That is, the gravity is very strong, so that no object can escape its pull.

The question of the hottest place in the universe could depend on the question being asked, says Black Hole Initiative researcher Koushik Chatterjee. He said the places with the highest temperatures were when major events occurred in space.

For example when two large objects collide. The explosion from that event would create a huge temperature spike.

A study published in the journal Nature Physics says that two neutron stars, collapsing massive star nuclei, will produce temperatures reaching 800 billion degrees Celsius.

Not only that, Chatterjee explained that a neutron star that collides with a black hole can also produce high temperatures. This cosmic collision was reported to have occurred in an instant.

Palumbo also admits that it is difficult to determine the hottest temperature in the universe. He stressed there was a problem at long distances with these objects.

“It’s difficult to study the temperature of objects that are very far away, you can’t measure it with a thermometer,” he said.
