In space, astronauts can actually become a little taller than they are on Earth. On our planet, Earth’s gravity constantly pushes down on the body and compresses the spine throughout the day. But in space, where there is almost no gravity, the pressure on the spine disappears. This allows the small discs between the bones in the spine to expand and stretch out, making astronauts grow about 2 to 5 centimeters taller temporarily. Once they return to Earth, gravity compresses the spine again and their height slowly returns to normal.

The extinct Terror Bird was one of the most terrifying predators of ancient times. These giant flightless birds lived millions of years ago in South America and had long powerful legs built for speed. Scientists believe some species could run faster than many modern racehorses while chasing prey across open land. Unlike birds today, Terror Birds used their massive sharp beaks like deadly weapons to attack and kill animals. Their incredible speed, height, and hunting skills made them one of the top predators of their era.
