In the world's largest vacuum chamber, a bowling ball and feathers are used for a real-life demonstration of a concept Galileo first proposed over 400 years ago.

More than 400 years ago, Galileo Galilei proposed that mass does not affect the speed with which an object falls. Now, using the world's largest vacuum chamber at NASA, we can confirm this fundamental principle of physics. xitter.gq/i/status/2031710479748…

🚨: Mount Everest contains marine rocks, proving that the highest point on Earth was once at the bottom of the ocean
Readers added context they thought people might want to know
While marine fossils exist on Everest, the region was part of the shallow Tethys Sea, not the ocean floor. The rocks were pushed upward by the collision of the Indian and Eurasian tectonic plates.
The fossil image (right) is AI-generated, confirmed via SynthID watermark.

🚨🇺🇸 Meanwhile in Hawaii
Mount Kilauea violently erupts, as authorities issue the first Ashfall warning in years with smoke rising over 35k ft.
Look at all that plant loving natural Co2 spewing into the atmosphere - but please keep thinking you need to stop eating meat, and using a petrol car to save the planet….

The intense blue of glacial melt water results from light scattering on glacial flour—finely ground rock sediment created by glacier movement.

Found only in the Galapagos Islands the marine iguana is the only marine lizard species in the world, they can dive as deep as 30m (98 ft) and spend up to 30 minutes at a time underwater.

Ground-to-cloud lightning occurs when a positively charged region on the ground beneath a storm creates an upward-moving leader that connects with a negative charge from the cloud, completing the circuit.

Commander Dave Scott of Apollo 15 validates Galileo's theory on the Moon by dropping a hammer and a feather, proving that objects fall at the same speed, independent of their mass.

The glacier melt water's intense blue color is due to fine silt particles, or glacial flour, in the water, result of glacial erosion.

Every second, the Sun ejects 1.5 million tons of material into space at hundreds of miles per second, but Earth's magnetic field protects it from the solar wind.

Devils Tower rising 264m (867 feet) above the surrounding terrain in northeastern Wyoming, an igneous intrusion that some believe is the remains of a volcano after erosion removed the surrounding rock.
