Same ball. Same height. 13 worlds. No air.

Earth beats Saturn. Mercury and Mars tie to a hundredth of a second. And the comet is STILL falling when this ends 🪐

Same ball. Same height. 13 worlds. Watch which one lands first.

Same ball. Same height. 13 worlds. No air. Watch which one lands first — and which two tie.

We dropped a steel ball from 100 metres above 13 worlds at once, in vacuum, in real time.

The Sun's is down in under a second. Then a five-way pile-up: Neptune, Earth, Saturn, Venus and Uranus all landing within half a second of each other.

Three surprises came out of it 👇

🔹 Earth beats Saturn — 4.52 seconds to 4.72. You'd weigh less at Saturn's cloud tops than you do sitting where you are.

🔹 Mercury and Mars tie — 7.35 and 7.36 seconds. Mars is nearly 1.4x the radius but about half the density, and the two cancel almost exactly.

🔹 The comet has no answer — 67P is so lumpy that its gravity depends where you stand. Seven minutes on the big lobe, closer to an hour out at the neck. It's still falling when the video ends.

Every fall time computed from NASA's surface gravity figures. Vacuum throughout — no air, no drag.

We solved this for Earth. Mars is still broken.

Mars has river channels dated to around 3.8 billion years ago — same faint Sun, half again as far out. Run the same arithmetic and early Mars sits at −78°C. To reach freezing it needed 78°C of greenhouse warming. Earth's entire greenhouse effect today is 34°C. Nobody has a clean answer, and some argue Mars was never warm at all.

Earth has a thermostat. It has been running for 4 billion years.

CO₂ gets pulled out of the air by rock weathering, and weathering runs faster when it's warm and wet. Warm planet → weathering speeds up → CO₂ drops → it cools. Cold planet → weathering stalls → volcanic CO₂ builds back up → it warms. That feedback has held Earth's temperature steady against a Sun that brightened by a third. It's also slow, which is why Earth still froze over completely, more than once.

The Sun Was Too Faint. The Oceans Were Liquid Anyway.

The Sun is about 30% brighter now than when it formed. Run the energy balance backwards four billion years and Earth's average surface temperature comes out below freezing — and below freezing isn't cold, it's a runaway, because ice reflects sunlight, which makes more ice.

So the early Earth should have been a frozen ball. Except we have the rocks.

Pillow lava from Isua in Greenland, 3.7–3.8 billion years old. Pillow lava only forms underwater — that isn't an inference, it's a cast of the water it cooled in. Zircons from the Jack Hills at 4.4 billion years. Stromatolites in the Pilbara at 3.43 billion.

Both sides are right. This episode is about what everyone assumed without checking.

Every number on screen was computed for this video from published constants, with the assumptions shown. Our figures check out against the published values: Earth's radiating temperature comes to 254 K and Mars's to 210 K, matching the NASA fact sheets.

WHAT WE FOUND
• The shortfall is 59 watts per square metre, continuously, for billions of years
• Removing every low cloud on Earth buys you about 25 of those 59 — less than half
• Ammonia was the first proposed fix, in 1972. Ultraviolet light destroys it in years
• A thicker nitrogen atmosphere was the next. Measurements of 3-billion-year-old quartz found the opposite
• The real answer is a thermostat: rock weathering pulls CO₂ down when it's warm, volcanoes put it back when it's cold
• But the Archean was not warm the whole way through — there are ice ages at 2.9 and 2.4–2.1 billion years
• Two authoritative reviews, eight years apart, reach different verdicts on whether the problem is solved
• Mars needed 78°C of greenhouse warming. Earth's entire greenhouse effect today is 34°C

The Sun was 25% fainter. Earth should have been solid ice.

Dim the Sun to three quarters and keep everything else the same — Earth's average surface temperature comes out below freezing. And below freezing isn't cold, it's a runaway: ice reflects sunlight, which makes it colder, which makes more ice. But we have pillow lava from Greenland dated to 3.8 billion years, and pillow lava only forms underwater. Both are right. Something we assumed is wrong.

One sunspot fired five flares in a day

On 25 August 2026, active region 4513 let go an M6.9 flare peaking at 10:02 UTC — then several more M-class flares inside about twenty-four hours, from that one region.

The coronal mass ejection that came with it was clocked at 603 km/s and Earth-directed. NOAA's Space Weather Prediction Center issued a G1 (minor) geomagnetic storm watch for 27 August and a G2 (moderate) for 28 August.

A G2 storm can push aurora further south than usual — potentially into the northern US and northern Europe. That's a forecast, not a sighting report.

A rocket nobody was steering hit the Moon

In January 2025 a Falcon 9 upper stage delivered its payload towards the Moon and then kept drifting, unpowered, for more than eighteen months.

On 5 August 2026 it hit the lunar surface at about 5,400 mph — an impact worth roughly three tonnes of TNT.

NASA's Lunar Reconnaissance Orbiter photographed the result from 60 miles up: a fresh crater about 60 feet across and less than 10 feet deep, with dark streaks of ejected surface material and bright rays where the blast exposed material that had never seen sunlight.

Saturn just grew a ten-sided storm

Saturn's north pole has had a six-sided jet stream for more than forty years. Nothing else in the solar system looks like it.

On 2 September 2026, a paper in Science Advances reported that the south pole now has one too — with ten sides. It was found in Hubble's long-running Outer Planet Atmospheres Legacy programme, and it isn't a surface cloud: it extends down through multiple atmospheric layers.

Nobody knows why it formed now. That's stated as an open question in the paper, not a solved one.

Webb found something that looks like a star and isn't

A paper in Nature on 12 August 2026 described MoM-BH*-1 — an object at redshift 7.76, seen as it was roughly 660 million years after the Big Bang.

It shines like a star. Nothing inside it is fusing. The light comes from gas falling into a black hole, wrapped in a hydrogen envelope roughly the width of our solar system.

How heavy is the black hole? Published estimates disagree — from about 100,000 solar masses up to a couple of million. We're not pretending that's settled. If the interpretation holds, it's a candidate missing link for how supermassive black holes grew so fast so early.
