We’ve all seen that vast black hole. Its six billion solar masses are so dense no light can escape. It is so far away light from hot gas falling in takes 55 million years to reach us. Well actually, we’ve seen an image. Now that we’ve seen it, what do we know now we didn’t […]
Ant-Man is back this week in a new sci-fi movie. Rumor says your favorite shrinking superhero’s set to shrink even smaller than before. This could set a trend. Will we soon see Ant-Man in action all the way down to Planck-scale? The sixties comics and the 2015 movie Ant-Man were about scale and a suit […]
Planck-scale physics is more than a hundred years old. Physics is starting to take it seriously. This is great because we can hope for exciting new science and technology to drive a new economy. Planck scale is the incredibly tiny scale at which physics actually happens. It is the scale at which space no longer […]
The Large Hadron Collider or LHC was to find new particles. Aside from possibly the expected Higgs boson the report from the physics front is a deafening silence. This silence says a lot. At some $10 billion, the LHC is the world’s biggest and most costly science experiment ever. It pushes atom-smashing to new energy […]
What is mass? An apple has it. Put one on a supermarket scale: Earth’s gravity guarantees you pay in precise proportion. In 1684 Isaac Newton does the math for mass and gravity. In 1915 Albert Einstein cleans it up. But a deep problem remains untouched: Up close and personal, neither Isaac nor Albert nor anyone […]
He that breaks a thing to find out what it is has left the path of wisdom. – J.R.R. Tolkien How can we possibly develop Planck-scale physics? Since 1899 we’ve known that Planck scale is incredibly tiny. We need to go there; it’s where the real action is. New theories (such as string theory) tap […]
The mystery of the missing WIMPs is heading for a crisis. It’s looking like the reason we can’t find them is they don’t exist. Most people never heard of them. What is a WIMP? It is Dark Matter by another name. It stands for Weakly Interacting Massive Particle. They must be weakly interacting because no-one’s […]
Good news for India and for science: welcome to a new sophisticated telescope called Astrosat. The India Space Research Organization (ISRO) designed and built it. Launched a month ago on India’s Polar Satellite Launch Vehicle from the Satish Dhawan Space Centre, it is now in its 400-mile high orbit over the equator. Astrosat has new […]
— For Bill Rachinger, sine quo nihil . . . CERN’s Large Hadron Collider or LHC is back in the news. And behind the scenes there is fine physics that is little-known. It is the world’s biggest machine. Liquid-helium-cooled magnets bend twin beams of hydrogen nuclei (aka protons) in a circle. They collide at up […]
