Black Holes

BLACK
HOLES

By Yohana Tan

Black holes are incredibly dense objects with gravity so intense that nothing—not even light—can escape once it passes their event horizon, the point of no return. At their core lies a singularity, a theoretically infinitely small and dense point. Many black holes are remnants of stars with over 10 times the mass of the Sun, making their gravitational pull enormous.

If you were to fall into a black hole, you'd first witness the gravitational distortion of stars, twisted around the perfect black circle. But the spectacle wouldn’t last long—soon you'd be pulled faster and faster toward the singularity, your body stretched by gravity into spaghetti, a process known as spaghettification. The gravitational pull on your feet would be vastly stronger than on your head if you fell feet-first.

However, imagine instead falling into a charged black hole—one that contains a one-way wormhole and two event horizons. This rare phenomenon could, hypothetically, connect to a white hole, which ejects matter instead of absorbing it. You’d fall between these two horizons in free fall, and if the black hole were as large as the one at the center of the Milky Way, the fall to the inner horizon would take around 20 seconds—20 agonizing seconds of extreme gravitational stress.

Upon reaching the inner horizon, the black hole would seem to shrink due to relativistic beaming, an optical illusion caused by high-speed motion. At that point, you'd witness a burst of light—a reflection of the entire history of the Universe. Crossing further into the wormhole, you'd face another burst—this time showing the Universe’s future.

Emerging from the white hole, you could find yourself in a completely different Universe governed by different laws of physics—where gravity might be absent, and matter made of dark matter or antimatter. If it's the latter, you'd face annihilation, as antimatter and matter destroy each other on contact.

And since white holes don’t allow entry, there would be no way back—a thrilling but irreversible cosmic journey.
