Meteorites do not fall to Earth
When a meteoroid hits Earth, it’s not because the space rock has “fallen out of” its orbit. It’s because its orbit crosses over Earth’s orbit at the exact right (or wrong) moment.

Dinosaurs were already doomed as the frequency of Asteroid Impacts increased 290 million years ago
By studying lunar craters, scientists have discovered that the asteroid impacts became more frequent about 290 million years ago. So was just a matter of time for dinosaurs to becoming extinct.

Five space probes leaving the solar system (for now)
As of 2019, only five space probes are leaving the solar system: Pioneer 10, Pioneer 11, Voyager 1, Voyager 2 and New Horizons. The Voyagers already left the solar system and entered the interstellar space (Voyager 1 on August 25, 2012, and Voyager 2 on November 5, 2018. The others also will leave the heliosphere Notes 1 and reach the interstellar space in a few years.
All of these spacecraft are launched by NASA.

Speed of Light – See how torturously slow it is
The speed of light is the Universal speed limit – nothing can travel faster than light. In the vacuum (commonly denoted c), its exact value is 299,792,458 meters per second (around 186,000 miles per second). In other words, if you could travel at the speed of light, you could go around the Earth 7.5 times in one second.
