Are addiction to smartphones and excessive screentime slowly influencing our brains to become more and more confused & unfocused? 💭📱🧠
Problematic smartphone use is linked to worse attention, weaker inhibitory control, more anxiety and depression, and poorer sleep, cognitive deficit, less efficient attention networks and lower gray-matter in control and reward regions (anterior cingulate, orbitofrontal cortex).
The Moon was slowed down by tidal locking with Earth. It used to spin much faster. Over billions of years, Earth’s gravity created tidal bulges on the Moon that acted like a brake (~27.3 days). That’s why we always see the same side of the Moon. 🌔👀

🌌 In 1929, Edwin Hubble demonstrated a linear relationship between a galaxy’s recessional velocity and its distance — known as Hubble’s Law. This empirical evidence showed the universe is expanding, providing the first observational basis for modern cosmology & Big Bang model 🔭

The statue of Prometheus is finally finished.
It was cast in Paris, crossed the Atlantic, and was assembled at Starbase. It took us 100 days to go from nothing to this.
People of the West, we have lived through an era devoid of dreams, devoid of destiny.
But the time has come to reclaim our dream of antiquity.
In a few months, we will start building a new city. It will be the most magnificent city in all of history.
After all, the great dream of the West has always been to rebuild Rome.
Come walk beside us in this endeavor. The world is waiting.

Starship will expand the aperture of physics research by placing much larger telescopes in orbit and giant ones on the Moon
Starship reached orbit for the first time on Monday. One of my favorite potential use cases is launching the next generation of space telescopes faster and with far fewer constraints.
Today, engineers designing the largest space telescopes face extreme mass and volume limits that forces them to make telescopes lighter, foldable, and dependent on incredibly intricate deployment mechanisms, adding years of engineering complexity and increasing the risk of failure.
Starship changes that tradeoff. Thanks to its massive payload capacity and volume, telescope builders could "convert risk into mass": build heavier, simpler observatories instead of optimizing every component around launch constraints.
That could accelerate the next generation of space telescopes, and astrophysics research, by decades!

A horrific scene of severe flooding at the Rasuwagadhi border point on the Nepal-Tibet border.
The strong currents wreaked havoc across the area, leaving 400 pilgrims and 105 Indian tourists also missing in the Nepal floods.

It’s time for takeoff. Welcome to Louisiana, @SpaceX.

“Think of the rivers of blood spilled by all those generals and emperors so that, in glory and triumph, they could become the momentary masters of a fraction of a dot.
Think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely distinguishable inhabitants of some other corner, how frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds.”
— Carl Sagan
