<p>The strange case for prime numbers at the heart of physics</p>
Prime numbers are natural numbers greater than 1 that have no positive divisors other than 1 and themselves. They play a crucial role in number theory and have applications in cryptography, computer science, and various mathematical theories.
Black holes are regions in space where the gravitational pull is so strong that nothing, not even light, can escape from them. They are formed from the remnants of massive stars that have collapsed under their own gravity and are a key area of study in astrophysics.
