NASA mapped the entire ocean floor using gravity from space.

🌊 The technique is called satellite altimetry. Satellites measure the height of the ocean surface with centimeter precision and because underwater mountains and trenches alter local gravity, they pull water toward them, creating subtle bumps and dips in the sea surface directly above them. The map it produces covers 100% of the ocean floor at roughly 5km resolution. Direct sonar mapping, which requires ships sailing back and forth, has covered less than 25% of the ocean floor despite decades of effort. We have higher resolution maps of the Moon, Mars, and Venus than we do of Earth's own ocean floor. The planet we live on is still largely unmapped because two miles of water is harder to see through than the vacuum of space. 📌 Source: Sandwell et al., Science New Global Marine Gravity Model from CryoSat 2 and Jason 1 Satellite Altimetry

India's coastline alone hides underwater cities. The Gulf of Khambhat has structures older than Egypt's pyramids beneath it 🇮🇳

NASA’s SWOT satellite enhances gravity-based seafloor mapping, spotting seamounts and abyssal hills smaller than previous detections allowed. This could expand known underwater peaks from 44,000 to nearly 100,000, shedding light on tectonic history and deep-sea ecosystems.

Where are all the bodies of Dexters victims? I don’t believe this shit

we know more about mars than we do about our own ocean floor and nasa just fixed part of that from space. insane sentence.

What if they’re not “exploring”… but monitoring what they already know is down there? 🌊👁️ Because mapping the ocean from space sounds more like control… than simple curiosity 🤔 What do you think they’re really hiding? 🔍

If all the seawater on Earth were drained, you would find that humanity is nothing more than a mob living on a mountaintop... The real Earth belongs to the many lives below.

Did they find the Megalodon in the Mariana Trench?

They find Atlantis?

Then where is MH370?

This is amazing.😧

Absolutely mind-blowing! 🌊🛰️ NASA's SWOT satellite is basically turning tiny sea-surface 'bumps' (caused by underwater gravity quirks) into a near-global 8 km resolution map of the entire ocean floor—something ship sonar has only scratched ~25% of after decades. It’s already revealing tens of thousands more seamounts we never knew existed, which could reshape what we understand about tectonics, deep-sea currents, and even biodiversity hotspots. And yeah… the fact we’ve had better maps of Mars and the Moon than our own planet’s oceans until recently is wild. Space tech helping us finally 'see' our backyard depths is peak 21st-century irony. What do you think this could unlock next new mineral sources, better tsunami models, or maybe even hidden ecosystems? 🚀 #SWOT #OceanExploration #NASA

How many pyramids did they find or alien bases?

Using subtle variations in Earth’s gravitational field measured by satellites like Jason-1 and CryoSat-2, scientists inferred the shape of the seafloor, since underwater mountains and trenches slightly alter gravity and thus sea surface height, allowing a near-global map of the ocean floor without directly imaging it.

NASA mapped the ocean floor… Still can’t explain why people argue over nonsense on social media 😳👀

Where are the alien bases?

fascinating

what kind of map is this

Progress

Did they find MH370 ?

We know more about space than our own ocean, wild.🥲

Wow, they even mapped the countries to be incorrectly sized just like our maps.

Genuinely one of the most remarkable scientific achievements in years

Amazing!

They'll find the ancient robots at the bottom, Exactly what happens on Mars

🤣🤣

They’re fucking liars

Using the planet's own gravity as a measuring tool to map the entire ocean floor is one of those ideas that sounds impossible until it works.

İts not this much rough ofc

What are they cooking 😂

So where’s Atlantis?

Amazing!!😃
