Oldest Sphinx statue found at Giza


(Ancient Architects) The oldest Sphinx statuette found at Giza, Egypt! Aug.18, 2025: Archaeologists have uncovered what may be the oldest Sphinx statuette ever found at Giza, hidden in a long-forgotten dump. Kromer Dump artifacts suggest there was a predynastic civilization or culture in Giza before the Fourth Dynasty related to the Maadi culture. The Oldest Sphinx Statuette Found at Giza

Science: There's NO objective reality

A quantum experiment suggests there’s no such thing as objective reality
TechnologyReview.com, 3/12/19

Physicists have long suspected that quantum mechanics allows two observers to experience different, conflicting realities. Now they’ve performed the first experiment that proves it. 

Back in 1961 the Nobel Prize-winning physicist Eugene Wigner outlined a thought experiment that demonstrated one of the lesser-known paradoxes of quantum mechanics.

The experiment shows how the strange nature of the universe allows two observers -- say, Wigner and Wigner’s friend -- to experience different realities.
Since then physicists have used the “Wigner’s Friend” thought experiment to explore the nature of measurement and to argue over whether objective facts can exist. That’s important because scientists carry out experiments to establish objective facts.

But if they experience different realities, the argument goes, how can they agree on what these facts might be?
 
That’s provided some entertaining fodder for after-dinner conversation, but Wigner’s thought experiment has never been more than that—just a thought experiment.

Last year, however, physicists noticed that recent advances in quantum technologies have made it possible to reproduce the Wigner’s Friend test in a real experiment. In other words, it ought to be possible to create different realities and compare them in the lab to find out whether they can be reconciled.
 
And today, Massimiliano Proietti at Heriot-Watt University in Edinburgh and a few colleagues say they have performed this experiment for the first time: They have created different realities and compared them.

Their conclusion is that Wigner was correct: These realities can be made irreconcilable so that it is impossible to agree on objective facts about an experiment. More

    Space: Farthest, Oldest Object Seen

    A stellar explosion has smashed the record for most distant object in the known universe.

    The gamma-ray burst came from about 13 billion light-years away, and represents a relic from when the universe was just 630 million years old.

    "It easily surpassed the most distant galaxies and quasars," said Edo Berger, an astrophysicist at Harvard University and a leading member of the team that first demonstrated the burst's origin. "In fact, it showed that we can use these spectacular events to pinpoint the first generation of stars and galaxies."

    "The burst most likely arose from the explosion of a massive star," said Derek Fox, an astrophysicist at Penn State University. "We're seeing the demise of a star — and probably the birth of a black hole — in one of the universe's earliest stellar generations."

    Gamma-ray bursts mark the dying explosion of large stars that have run out of fuel. The collapsing star cores form either black holes or neutron stars that create an intense burst of high-energy gamma-rays and form some of the brightest explosions in the early universe.

    A light-year is the distance that light can travel in a year, or about 6 trillion miles (10 trillion kilometers). So astronomers are seeing this particular burst as it existed 13 billion years ago, because... More>>
