🌍 What If Earth Stopped Spinning for Just One Second?

Imagine it’s an ordinary day. The wind hums softly, waves lap the shore, and you’re scrolling your phone, unaware that the planet beneath your feet is hurtling eastward at about 1,670 kilometers per hour. Then, suddenly—without warning—Earth’s rotation stops. Completely. For just one second.

The moment it halts, inertia takes over. Everything not physically anchored to solid bedrock would continue moving at the original rotational speed. Cars, oceans, entire city skylines—and you—would be launched eastward at over 1,000 mph.

It wouldn’t be a breeze; it would be annihilation. Skyscrapers would shear off their foundations, trees would rip from the ground, and oceans would surge inland as megatsunamis hundreds of meters tall. The air itself—also moving with Earth—would slam into the suddenly stationary surface at hypersonic speeds, shredding everything in its path.

In a single second, civilization would be pulverized. The initial burst would flatten continents near the equator, where rotational velocity is greatest. Closer to the poles, where Earth’s rotation is slower, the effects would be milder—but “mild” still means being sandblasted by a supersonic hurricane.

Then, after that one second, Earth starts spinning again. But by then, it wouldn’t matter. The atmosphere would be in chaos, the crust fractured, and the planet reshaped by unimaginable forces.

The physics behind this nightmare lies in angular momentum—the stubborn tendency of moving things to keep moving. You, right now, are spinning with Earth’s surface, and the only reason you don’t feel it is because everything else around you spins too. Stop the rotation, and you separate those frames of reference. Suddenly, “stationary” and “moving” mean very different things.

Even if the planet somehow survived the mechanical violence, its magnetic field—generated by the motion of molten iron in Earth’s core—would be disrupted. Without it, cosmic radiation and solar wind would slowly strip away the atmosphere.

If you somehow wanted to stop Earth safely, you’d have to dissipate its rotational energy—roughly 2.14×10292.14 \times 10^{29} joules. That’s about a billion times the energy of the largest nuclear bomb ever detonated. You’d sooner boil the oceans dry than brake the planet.

The takeaway? Rotation isn’t just a background feature—it’s a cosmic balancing act. It shapes day and night, weather, ocean currents, even the magnetic shield that protects life itself.

So next time you complain about the world moving too fast, remember: it should keep spinning. Because if it ever stopped, even for a heartbeat, that heartbeat would be Earth’s last.

Cancer Killing Viruses: The What? The How? & The What if?

Image
Treating cancer has been puzzling doctors since antiquity. With the first unsuccessful attempt at surgically removing a tumour being nearly 4,000 years ago in ancient Egypt, the field of cancer biology has certainly come a long way. In order to combat a disease like cancer, an entirely new paradigm-shifting approach to medicine, “Gene Therapy”, has shown remarkable success in curing certain types of cancers in adults as well as in children and has saved millions of lives across the world.  The most notable advancement in the field of cancer immunotherapies is without a doubt: the advent of CAR-T cells or 'Chimeric Antigen Receptor T-cells'. CARs are engineered receptors that effectively redirect T cells to cancer surface proteins that express a particular target biomarker . The unprecedented success of the anti-CD19 CAR T-cell in curing leukemia and lymphoma resulted in the approval of the first CAR-T cell therapy by the US-FDA in 2017 . While CAR-T cell therapy demonstrates r...

Why does the QWERTY keyboard layout exist?

Image
Surely almost everyone who has used a computer has pondered this question, just why does the QWERTY keyboard exist? The alphabet goes “ABCDEF” not QWERTY so wouldn’t it be typical to apply that instead of this odd, seemingly random format? You might assume QWERTY was the best option, but what if I told you the real story is far weirder? First let’s talk about some alternatives we have to the typical QWERTY keyboard– from today and the past. One is the stenography keyboard, it’s an extremely odd layout that doesn’t even contain all the letters of the alphabet. What makes it a unique alternative isn’t about how the alphabet is organized differently on it– putting aside the fact that the entirety of it isn’t even present on the keyboard– but what it is actually supposed to do. A stenography keyboard is designed to maximise efficiency, rather than typing the spelling of a word it requires you to type the way the word is pronounced, and the lesser letters don’t hinder this, they enable you ...

What if the Earth stopped spinning for 5 seconds?

Image
As you might know, the planet we live on spins at incredibly high speeds at all times. At the equator– which is the fastest part of the earth– the Earth reaches speeds of around a whopping 1,670 kilometres per hour, for reference, the sound barrier is broken around 1,234 kilometres per hour so if anything else moved at that kind of speed it would be outstandingly fast.  So then this brings forth the question, just why are we fine if the planet is spinning this fast? Well that’s because of the gravity that saves us, it counters the centrifugal force– in a sense– of the earth’s speed that would have otherwise flung us faster than the speed of sound. Now this brings forth an even more interesting doubt, just what exactly would happen if the earth ceased this rotation for let’s say, 5 seconds? Well a quick spoiler– it would be devastating!  One might think that there won’t be any other effects other than us getting dizzy since the earth’s spin that we’re so used to is no longer th...
