KOMPAS.com – The sun is the hottest object in the solar system, but not in the entire universe.
The temperature of the sun is nothing compared to some other cosmic bodies in the universe.
Theoretically, the hottest places in the universe are regions close to supermassive black holes.
This is primarily a supermassive black hole that grows in size, because it feeds on gas, causing the surrounding region to become very hot.

The hottest place in the universe
Reporting from the IFL Science page, when material falls into a black hole, the material heats up and releases energy in the form of electromagnetic radiation.
In some cases, this leads to the formation of very hot and bright quasars (active galactic nuclei) located several light years around the center of the black hole.
It can emit thousands of times more light than the Milky Way, making it possible for humans to see it.
According to a 2016 study of quasar 3C273, the plasma around the black hole has a temperature of around 10 trillion degrees Celsius, making it the hottest place in the universe.

Not only is this possible due to the existence of a hypernova, but although it varies slightly, it is also widely held because it was the first quasar discovered.
Despite being 2.4 billion light years from Earth, 3C273 is a bright quasar visible through certain telescopes.
Whether at the heart of a quasar or inside a particle smasher, nothing today can match the heat that occurred immediately after the Big Bang.
Before it finally cools, this temperature is estimated to be in the range of billions of times hotter than quasar 3C273.

Quoted from the Live Science page, the hottest place in the universe ever recorded is quasar 3C273.
This is a brightly shining region around a supermassive black hole which is about 2.4 billion light years from Earth.
Quasar 3C273 has a core temperature of about 10 trillion kelvin (more than 10 trillion degrees Celsius). But there is still uncertainty surrounding these temperature estimates.

Just like other black holes, quasar 3C273 has a gravitational pull so strong that nothing, not even light, can escape from it.
Although the interior is very cold, the ring of gas (accretion disk) rotating around it is quite the opposite.
When molecules are sucked into a black hole at high speed, the friction generated by collisions between these materials can cause temperatures of trillions of degrees Celsius.
And for comparison, the surface temperature of the sun as the hottest object in the solar system is only 5,500 degrees Celsius.
