Astronomers may soon have the answer to what is perhaps the greatest mystery of modern science is dark energy a uniform force across space and time, or has its strength evolved over eons?

Moore’s Law Homo Sapiens May be the Milky Way’s First Intelligent Civilization Posted on Oct 11, 2021

As life has evolved its complexity has increased exponentially, just like Moore’s law, which states that the number of transistors on an integrated circuit doubles approximately every two years. The regression suggests that if life takes 10 billion years to evolve to the level of complexity associated with homo sapiens, then we may be among the first, if not the first, intelligent civilization in the Milky Way, negating Drakes Equation.

Colossal Cosmic Cold Front Survived Over 1/3 the Age of the Universe (Weekend Feature) Posted on Oct 9, 2021

A colossal cold front hurtling through the Perseus galaxy cluster spans about two million light years and has been traveling for over five billion years, over a third of the age of the universe, longer than the existence of our Solar System. Astronomers expected that such an old cold front would have been blurred out or eroded over time because it has traveled for billions of years through a harsh environment of sound waves and turbulence caused by outbursts from the huge black hole at the center of Perseus.

Black Hole Enigma Does the Event Horizon Exist? Posted on Oct 8, 2021

Could there be as yet unknown supermassive objects lurking at the hearts of galaxies other than black holes? An object so strange that it has managed to avoid gravitational collapse to form a singularity, the smallest object in the universe in an infinitely Planck-scale space, where density and gravity become infinite and space-time curves infinitely, and where the laws of physics as we know them cease to operate?

The Great Collision Epic Unprecedented Change to Life On Earth Posted on Oct 7, 2021

 

“Contrary to our first expectations, global climate was not the primary cause of this change in ocean oxygen and nitrogen cycling,” said biogeochemist Emma Kast currently at  the University of Cambridge about the planet’s dramatic increase in oxygen 55 million years ago. The more likely culprit? Plate tectonics. The collision of India with Asia — dubbed “the collision that changed the world” by Columbia University geoscientist Wally Broecker, a pioneer in the ocean’s role in climate change.— closed off an ancient sea called the Tethys, disturbing the continental shelves and their connections with the open ocean.

Plancks Star A Primordial Object the Age of the Universe Posted on Oct 6, 2021

The final stage in the life of a star, observes physicist Carlo Rovelli in Seven Brief Lessons on Physics, where the quantum fluctuations of space-time balance the weight of matter, is what is known as a Planck star. If the sun were to stop burning and to form a black hole, the event horizon would measure about six kilometers in diameter. The black hole’s event horizon is not a physical barrier, but simply the boundary where the black hole’s gravitational field becomes so intense that the escape velocity exceeds the speed of light. Nothing, not even light, can escape the event horizon.
