What we need to know about Planck stars
How long do they take to explode?
While we think Planck stars are stellar explosions in slow motion, we aren’t entirely sure how long they take. We’ll need to know that if we ever want to spot one.
Where are they?
If Planck stars do really exist, it might be possible to spot some of them exploding in our night sky. However, we haven’t been able to track
any down as of yet.
Were they in the early universe?
It’s possible Planck stars were present in the early universe, in the form of primordial black holes. If we can find some of these, we might be able to find a
Planck star.
Have we seen some already?
Planck stars are thought to release large amounts of gamma rays when they
explode. We’ve already detected many gamma-ray
bursts in the universe – could some of those bursts we’ve found be Planck stars?
What size are they?
Black holes come in a variety of sizes, but do Planck stars as well? Smaller ones would explode more quickly, so we’d be able to spot them more easily in the universe.
