Mystery over hot object in space that’s confusing scientists

Scientists have identified an unexpectedly hot cluster of gas in the early universe, observed just 1.4 billion years after the Big Bang.
The gas within this cluster, designated SPT2349-56, is at least five times hotter than predicted for that cosmic period, initially causing researchers to doubt the findings.
The intense heat is attributed to three supermassive black holes within the cluster, a powerful phenomenon not expected so early in the universe's development.
This discovery challenges current understanding of how galaxy clusters, which are fundamental to the universe's structure, initially formed and evolved.
The findings, published in Nature and based on observations from the ALMA telescope, suggest a more explosive birth for galaxy clusters than previously theorised.
