The second law of thermodynamics says that the total entropy of a closed system cannot decrease. Entropy is a measure of how many microscopic states are possible in a system.
At first, black holes might seem to have very little entropy because they are described by only a few properties, such as their mass, charge, and angular momentum.
However, in 1972, physicist Jacob Bekenstein proposed that black holes should have entropy.
His argument was based on the second law of thermodynamics. If an object with entropy falls into a black hole, its entropy would no longer be directly accessible outside the black hole. If the black hole had no entropy of its own, this could lead to a decrease in the total entropy of the universe, which would conflict with the second law.
So, how much entropy does a black hole have?
In 1974, Stephen Hawking showed that black holes have a temperature and emit thermal radiation, now called Hawking radiation. This means that black holes have thermodynamic properties.
Using the relationship between energy, temperature, and entropy, physicists found that the entropy of a black hole is proportional to the area of its event horizon.
This result is known as the Bekenstein–Hawking formula:
S = A/4ℓₚ²
where S is the black hole's entropy, A is the area of its event horizon, and ℓₚ is the Planck length.
The important point is that black holes do not violate the second law of thermodynamics. Instead, they can contain an extremely large amount of entropy. For a given region of space, a black hole represents the maximum possible entropy allowed by known physics.
So, although a black hole looks simple from the outside, its entropy can be extremely large.

It is indeed a disgrace. Those publications have an obligation to adhere to the truth and yet have become woke propaganda outlets.

This is what Tesla’s Robotaxi app looks like when your Cybercab arrives.
The screen glows to match whatever the color the RGB front light bar is on the Cybercab, while an arrow points to where the vehicle is located. You can also flash the lights and honk the horn to identity it.

Our society has gaslit its young women about their reality in terrible and destructive ways.
The Missing Data Depot@data_depot· Sep 2, 2026Young women's perceptions about how they are treated (particularly by men) have changed radically over the last 15 years.
In 2011, ~75% of young women believed women are treated w/ respect in America.
By 2024, however, that number had fallen to only 40%.

When you start a chess game, you have 20 possible moves available. After the first full move (White then Black), there are already over 400 possible positions. By the third move, that number jumps to around 8,900, and after the fourth it reaches nearly 200,000.

10 years after starting Hugging Face, open-source AI is at an inflection point. Thanks to the community, we’ve shown that it can be a complement, and even an alternative, to closed-source APIs. But for it to happen at larger scale, it needs more compute, more support, more collaboration and more visibility. That’s why we went to talk to Jensen, who offered to do exactly that with us.
In addition to doubling down on NVIDIA’s massive contributions to open-source AI (I called them the “King of American open-source AI” earlier this year), they’ve committed to strongly supporting Hugging Face and our mission while keeping the platform open, independent and compute agnostic. The founders and the team are all staying to keep pushing this mission forward.
Together, we think we can make open source the default way to build AI, with the goal of empowering 100 million AI builders to own their intelligence rather than rent it.
Excited about the next 10 years! 🤗🤗🤗

Ryan's Model Y@ryanjaycowan· Sep 3, 2026Today I drove past a house for sale that looked nice ... So I asked Grok in the Tesla how much it was. It pulled the listing, price, beds/baths, square footage, days on market, and market analysis — all while FSD kept driving. No phone. No searching. Just talking.
