Deep within our Milky Way, near its center, lies Sagittarius B2 an enormous molecular cloud packed with gas and dust. But this isn’t just any cosmic cloud. It contains a staggering amount of ethyl alcohol the same kind that’s in alcoholic drinks, enough to brew 400 trillion pints of beer.

This discovery blows open our understanding of the universe’s chemistry. Complex organic molecules like alcohol don’t just exist here on Earth they form naturally in the harshest corners of space. On tiny dust grains, simpler molecules combine and react, creating the building blocks that might one day give rise to life.

Using powerful radio telescopes, scientists have captured the unique “fingerprints” of these molecules, revealing a cosmic chemistry lab that’s been brewing for millions of years. The presence of alcohol and other organic compounds out there is a thrilling hint that the ingredients for life could be scattered all across the universe.

A Teaspoon of Neutron Star Material Weighs a Billion Tons

A neutron star is what’s left after a massive star explodes in a supernova and its core collapses. The gravity is so intense that protons and electrons are crushed together into neutrons, forming one of the densest objects in the universe.

![](https://m.stacker.news/92481)

To put it in perspective:

✓1 teaspoon of neutron star matter = ~6 billion tons (5.5 x 10¹² kg)
That’s about the weight of all the human-made structures on Earth combined.

✓The density is roughly 400 million tons per cubic inch.

✓If you dropped that teaspoon of neutron star on Earth, it would punch straight through the planet like a bullet through tissue paper nothing could hold its weight.


Neutron stars are so dense that their gravity warps space time, and their magnetic fields can be trillions of times stronger than Earth’s. They spin rapidly some hundreds of times per second and can emit beams of radiation like lighthouses in space (called pulsars).

It’s one of the most extreme, alien objects in existence and yet it's a natural outcome of star death.

One Signature to Rule Them All, the Power of MuSig2 on Bitcoin

Stacker_Stocks

Is the Stock Market Just a 400 Year Old Game?

Either way, reality takes a back seat to narrative.


The implementation of MuSig2, a groundbreaking multi signature scheme for Bitcoin. This protocol allows multiple parties to collaboratively produce a single, compact signature, enhancing both privacy and efficiency in Bitcoin transactions.

Key Highlights of MuSig2:

•✓ Enhanced Privacy: MuSig2 enables multiple signers to create a single aggregated signature, making multi signature transactions indistinguishable from regular single signature ones on the blockchain. This obfuscation enhances user privacy.

•✓ Efficiency Gains: By reducing the size of multi signature transactions, MuSig2 optimizes block space usage, leading to lower transaction fees and increased throughput.

•✓ Security Improvements: The protocol incorporates safeguards against rogue key attacks, ensuring the malicious actors cannot compromi signing process.

For a deeper dive into MuSig2 and its implications for Bitcoin's scalability and privacy, you can refer to the Bitshala BitDevs GitHub repository, which provides detailed discussions and resources on this topic.

This development is a testament to the continuous innovation within the Bitcoin community, showcasing how collaborative efforts can lead to significant advancements in blockchain technology.

Do you think they might give Concorde another chance in the near future?

There’s a rare neurological condition called Mirror Touch Synesthesia where people literally feel what they see others experience. Not emotionally physically.

![](https://m.stacker.news/92463)

![](https://m.stacker.news/92465)

Here’s how wild it gets:

✓If they see someone get slapped, they feel a slap on their own cheek.

✓If someone is touched on the shoulder, they feel a ghost touch in the same spot.

✓Some can’t handle crowds or medical shows because the input becomes overwhelming.

![](https://m.stacker.news/92466)

Brain scans show they have hyperactive mirror neurons the same system that helps us empathize but theirs don’t stop at observation. Their brain maps other people's experiences onto their own bodies.

It’s like being stuck in a constant, involuntary neural VR of everyone around you.

•Have you heard of this before?
•Could this kind of hypersensitivity become useful in human-ai interaction or virtual reality design?

What If We’re in a Simulation and Sats Aren’t Even Real?

•There was a moment in history when you could board a plane in London, sip champagne at Mach 2, and land in New York before your local departure time.

•That wasn’t science fiction. That was the Concorde.

![](https://m.stacker.news/92450)

![](https://m.stacker.news/92451)

•A supersonic masterpiece, flying at over 1,350 mph, the Concorde turned a 7-hour transatlantic slog into a 3 hour flex. You’d leave Heathrow at 10:30 AM and arrive at JFK at 9:20 AM. Earlier than you left. Wild.

•It was loud. Expensive. Inefficient. But it worked. For nearly 30 years, we lived in the future and then, in 2003, we walked away.

•No more sonic booms. No more time-bending flights. Just a quiet return to slow skies and economy seats.

Now, two decades later, the question feels louder than ever:

✓Why did we stop?

✓Was it cost? Carbon? Complacency?

And more importantly:

✓Is it time to start again?

•Startups like Boom Supersonic, along with legacy aerospace giants, are betting on a new wave of sustainable, faster than sound travel. But the world’s changed. Carbon footprints matter. Scalability matters. Equity matters.

So we’re left with a choice:

✓Was Concorde a beautiful, unsustainable blip or a prototype we abandoned too soon?

Curious what others think.
Is the dream of supersonic flight dead or just waiting for better timing?

Thanks means a lot coming from a higher level stacker like you.


The more you look at it, the more it feels like strategy, psychology, and timing matter more than fundamentals.


The Amsterdam Stock Exchange kicked off in 1602. Four centuries later, we still call it “investing” but what if it’s more like playing a very old complex game?

![](https://m.stacker.news/92433)

![](https://m.stacker.news/92435)

Here’s what blows my mind:

✓ Most short term price moves aren’t about fundamentals they’re about emotion: fear, hype, FOMO.
✓ Retail traders aren’t trading against people anymore they’re up against bots and HFT algorithms executing in microseconds.
✓ Stocks rise or fall not based on reality but on expectations of reality. It's not earnings, it's vibes.
✓ Most stocks don’t return profits directly (dividends) they sell narratives about future value.
✓ Those who win aren’t necessarily the smartest they’re the ones who understand it’s all a probabilistic, sentiment driven game.

So my question is:

Are we investing or just simulating rational behavior inside a highly gamified financial engine?

If the stock market is a simulation, who’s the player… and who’s played?




Yeah basically and I’ll be stacking until the devs pull the plug.

If we are in a simulation, love may still be the most authentic signal within it.

Maybe,but if it feels real,costs time,and burns energy it’s real enough for me.
