How the Universe Ends

Somewhere between a second and a millennium from now, you will die. Your body and all of its parts will cease functioning and rejoin the Earth as regular, lifeless stuff. The Earth, too, will die, engulfed by an expanding, aging Sun. The Sun will burn off all of its fuel and end up a white dwarf, then burn out and…Read more...

Assembling an Image of the Shadow of a Black Hole

In a mind-boggling excerpt from Seth Fletcher’s book Einstein’s Shadow: A Black Hole, a Band of Astronomers, and the Quest to See the Unseeable (published by Ecco), the author probes the meticulous process behind the Event Horizon Telescope (EHT). In fact, a series of collaborative data sets collected in 2017 by eight telescopes around the planet, the EHT aims to create an image of the shadow of a …

Astronomers Spot a Black Hole Sucking Up an Earth-Size Clump of Matter

You might think of black holes as enormous vacuum cleaners, sucking in all the matter and light that ventures too close. But confusingly, scientists normally see stuff leaving the area around a black hole, via jets of matter and light from ripped-apart dust. It’s rare to see matter get devoured.Read more...

The Only Known Sound in Space Is This 'Singing' Black Hole

Everyone knows there is no sound in space. After all, a sound wave requires a medium, like air or water, to travel through, and space is mostly a vacuum. But in studying a nearby galaxy cluster, astronomers detected a true occurrence of sound in space—and in this case, the incredibly deep sound was coming from a black…Read more...

Supermassive Black Hole Stretches Starlight, Proving Einstein Right Again

Albert Einstein’s theory of general relativity is magnificent. For a hundred years, it has consistently predicted all sorts of wacky phenomena scientists have later observed throughout space. One international team is now announcing that a 26-year-long observation campaign has once again confirmed the theory. Read more...

Scientists Find Stronger Evidence for New Kind of Black Hole

We’ve seen supermassive black holes at the centers of galaxies tearing stars to shreds. We’ve detected the energy wave from relatively tiny black holes slamming together to create a wobble in space-time a billion light-years away. But what about the medium-sized black holes in between these extremes?Read more...

Could Higgs Bosons and Primordial Black Holes Explain Dark Matter?

Without an actual discovery, it can be difficult to convince us laypeople that there’s really such a thing as “dark matter.” It seems to interact with our universe solely through gravity, and no experiment has detected it here on Earth yet. So what if there’s an explanation to what’s causing the dark matter’s using…Read more...
