The object might be as massive as 100 suns—if it even exists.
The universe is expanding, but no one can agree on exactly how fast.
Black holes are somehow able to grow constantly without changing their size. Physics might finally be able to explain why.

H2O is older than the sun, and could play a key role in helping planets grow.
After a century of debate, an alternative theory that favored classical reality has finally met its ruin.
A new analysis could put the question of cosmic expansion to rest once and for all.
By picking up on patterns too subtle for humans to notice, non-line-of-sight imaging can see around corners and through walls.
A new conjecture in physics challenges the leading “theory of everything.”
The concentration of metals in our star will determine when it dies, but scientists struggle to settle on an estimate.
When Victoria Meadows needs to ponder life on distant planets, she surrounds herself with earthly vegetation.
The Milky Way's deep past is beginning to come into view.
For two decades, one research team has detected collisions between dark and ordinary matter—but no one else can replicate their findings.
Using the wrong method to analyze a data set can yield misleading results. So one researcher is championing an approach that works for nearly everything.
Physicists have long grappled with the perplexingly small weight of empty space.
The experiment would confirm that gravity is a quantum force.
Our universe could be expanding and contracting eternally.
Physicists are looking far beyond solids, liquids, and gases.
String theory is considered the leading “theory of everything,” but there’s still no empirical evidence for it.
Colliding neutron stars could settle the biggest debate in cosmology.
