The Universe is a compact sheet of space and time with all the matter from the observable baryonic matter to the invisible dark matter and dark energy all occupying its distinct positions. Our Earth is the only known habitable planet in our entire observable Universe. Life on our planet is made sustainable by our Sun and it is shielded from the asteroid attacks by giant planets like Jupiter. So what are the forces in the Universe that can destroy the Earth? Well, here are some of the wilder possibilities.
Swallowing by a Blackhole: Black holes are the stellar remnants of a dead star that had undergone supernova explosion. As the matter is compressed into a tiny space, where the gravity is so strong that even light cannot escape. we know that there is a supermassive black hole present at the center of the milky way galaxy. If our solar system falls under the clutches of the heavy gravitational pull of the black hole, then the black hole swallows the Sun along with all the planets including Earth.
Hit by gamma-ray bursts from a magnetar: Magnetars are the Neutron stars with extremely powerful magnetic fields ranging from 10^9 to 10^11 Tesla which is quadrillion times powerful than our Earth's Geomagnetic Field. Magnetars rotate at extremely high velocities and release powerful gamma-ray bursts in the entire Universe in the process in different directions. We can detect the gamma-ray pulses from a magnetar which is thousands of light-years away if the direction of propagation is positioned towards the Earth. If a magnetar somehow comes close to the solar system (closer than our nearby star), the gamma-ray bursts that can destroy the Earth's magnetic, and the x rays released in the process could be lethal to the living beings on the Earth. ( the nearby magnetar is more than 9000 light-years away)
Hit by an asteroid. Asteroids are the remnants that are leftover during the early solar system formation. They are the minor planets with size ranging from few micrometers to as large as 950 km (Ceres). They are orbiting around the sun by forming belts in the region between Mars and Jupiter. These two planets are shielding the Earth from these asteroids. Dinosaurs are said to become extinct by an asteroid collision millions of years ago. If an asteroid of the size of New York escapes Jupiter's gravitational perturbations and collides with Earth, it would be equivalent to a trillion atomic bombs and the shock waves emanating from the collision is enough to wipe out all the species on the planet
ENDNOTES: All the above-said events are time-bound and will not happen for the next 100 million years. The above-mentioned facts are assumptions made from the recently discovered facts about black holes, magnetars, and the asteroids. The above-mentioned facts may or may not happen, but we human beings are the biggest threat to the Earth than any supermassive black holes or the most powerful magnetars in the Universe.
