A group of astrophysicists has reanalyzed the masses of galaxy clusters and they say that we might not need dark matter after all.

You’re witnessing a 2D projection of a 3D shadow cast by a 4D tesseract.

As it rotates through the W-axis, the "inner" and "outer" cubes swap roles: a spatial inversion that feels like a glitch only because our biology is trapped in 3-space.
It’s a hauntingly beautiful reminder that our "reality" is often just a lower-dimensional cross-section of a much more complex structure. Perspective is everything.

This is used in high-dimensional data visualization, hypercube topologies in parallel computing networks, and exploring the geometry of extra dimensions in theoretical physics.

Astrophysicists have found evidence of UAPs in old photographic plates. Something seems to have been orbiting around our planet before we had satellites! This finding has been independently confirmed. Still, scientists are afraid to speak out. @DrBeaVillarroel @Rizstanford

#Privacy is a big deal, and we need your help! 🙏 It's not as glamourous as ethical hacking, but safeguarding our data is crucial for our industry and moreso the individuals we protect. Please support the "Surveillance Accountability Act" introduced today by @RepThomasMassie, @RepBoebert and the amazing @naomibrockwell of the @LudlowInstitute #GetAWarrant

The louder professionals are, the more they will act!

Paschen’s law:
V_b = (B p d) / [ln(A p d) - ln(ln(1 + 1/γ))]

Pull the plunger on a syringe next to a live Tesla coil and watch physics lose its mind.
The instant pressure drops, that p d term collapses; breakdown voltage craters, the field ionizes the rarefied air, and violet plasma arcs flood inside the barrel like lightning bottled in glass.

No more jumping to the needle. Just pure glowing discharge channels forming in vacuum.
This is the exact reason vacuum tubes, neon signs, and Crookes tubes exist.

This Polish theoretical physicist just proved you can recreate all math functions from JUST one operation.

E(a, b) = e^a - ln(b)

Every single operation: +, -, x, / , trig, log, as you can see below.

Extremely mathematically elegant.

Watch hydrogen atom wavefunctions smoothly transition between quantum states (n,l,m)

This is the actual probability density of finding the electron; not just static orbitals, but the real quantum dance as it morphs between energy levels.

Yep! This would sound strange to anyone who got into computing from the year 2000 onward, but we really did spend hours and hours typing in BASIC code from computer magazines. In my case, it was on my Commodore 64.

Who else did this?

A hexagonal ring of squares doesn’t just look pretty— it folds into a perfect cube.

This graceful transformation reveals the power of topology: how flat surfaces become strong 3D forms through clever alignment and folding.

Scientists put kids through 100 hours of reading, then scanned their brains. New wiring had physically grown inside the language regions. Communication between brain areas sped up by a factor of 10. Kids who didn't read showed zero change.

That was a 2009 Carnegie Mellon study. It gets wilder.

In 2013, Emory University scanned 19 students every morning for 19 straight days while they read one novel chapter each night. Mornings after reading, the brain areas responsible for understanding other people's emotions lit up with new connections. So did the region that processes physical sensation. Their brains were simulating what the characters felt, as if it were happening to them. Those changes stuck around for 5 days after they finished the book.

Now flip to scrolling. A massive review published in Psychological Bulletin last September pulled together 71 studies covering 98,299 people. Heavy short-form video use (TikTok, Reels, Shorts) showed a clear pattern: worse attention, weaker self-control, and more anxiety. Consistent across teenagers and adults, across every platform tested. Oxford didn't name "brain rot" its 2024 Word of the Year for nothing.

A 2024 brain wave study found that people hooked on short-form video had weaker activity in the front of the brain, the part that controls focus and impulse control. Separate brain scans showed the same thing: heavy scrollers had less activation in the exact regions that deep reading strengthens.

UCLA neuroscientist Maryanne Wolf has been studying this for decades. Humans were never born to read. There's no gene for it. Reading is something we invented, and it hijacked neurons that were originally meant for recognizing faces. Over time, it built entirely new brain circuits connecting language, vision, and emotion. But those circuits only survive if you use them. Stop reading, and they fade. Wolf's conclusion is simple: screens built for speed produce a speed-wired brain. Books built for depth produce a depth-wired brain.

One honest caveat: most of these studies are snapshots, not long-term tracking. People who already struggle to focus might just prefer short videos. But the same pattern showing up across nearly 100,000 people is hard to shrug off.

The tweet repeats the line seven times. The research backs it up with brain scans, EEG data, and white-matter imaging across tens of thousands of people.
