The earliest black holes in the universe may not have disappeared from Hawking radiation after all, new research hints.

The early universe has a lot more massive black holes than suspected.

The Big Bang theory has dominated our understanding of the universe’s origin for almost 100 years. It describes a moment when all of space, time, and energy were born from a single infinitely dense ...

As gas falls toward a black hole, it heats up and shines. If the glow becomes intense enough, it can push incoming gas away. Astronomers call this balancing point the Eddington limit, and for decades ...

Physicists have started to treat a once-fringe idea with surprising seriousness: that our entire observable universe might be the interior of a black hole that formed in some larger cosmos. The notion ...

The oldest and most distant black hole known to scientists dates back 13.3 billion years ago, when our universe was still in its teething stage, according to findings published this month. The ...

Some things in cosmology may simply be unknowable. Why is there something rather than nothing? What lies outside the universe? What is inside a black hole? That last one has been niggling at ...

Astronomers may have finally cracked one of the universe’s biggest mysteries: how black holes grew so enormous so fast after the Big Bang. New simulations show that early, chaotic galaxies created ...

An international research team led by scientists at Waseda University and Tohoku University has discovered an extraordinary quasar in the early universe that hosts one of the fastest-growing ...

In May 2019, astronomers picked up something strange in the fabric of spacetime. The LIGO and Virgo detectors recorded a gravitational wave that lasted just one-tenth of a second. The signal, known as ...
