Johns Hopkins University study of 10 billion years of microwaves reveals a warming predicted by dark matter theory.
Who says you can’t get hotter with age?
Researchers from Johns Hopkins University and other institutions have found that, on average, the temperature of galaxy clusters today is 4 million degrees Fahrenheit. That is 10 times hotter than 10 billion years ago, and four times hotter than the Sun’s outermost atmosphere called the corona. The findings are published in the Astrophysical Journal.
