Neutrinos: The Ghost Particles of the Universe

November 6, 2024

A surreal, almost abstract image depicting the elusive nature of neutrinos. Imagine a vast, dark expanse of space, a deep indigo void speckled with distant stars. Through this void, a stream of ghostly, shimmering particles - neutrinos - flows in a vibrant, swirling pattern of electric blue and neon green. These particles are almost invisible, but their movement leaves a trail of light and color, hinting at their presence and suggesting the incredible scale of the universe. The scene should convey a sense of mystery and awe, emphasizing the unseen forces at play in the cosmos.

Among the most plentiful particles in the universe, neutrinos are also quite elusive and travel through matter virtually undetectably. This page clarifies these ghost particles, showing how our knowledge of physics has evolved from solar activities to supernova explosions. Visiting an underground neutrino detector let me see the scope of research required to find these ...

Unseen Forces: The Quest to Understand Dark Matter

November 4, 2024

A cosmic landscape, a canvas of deep indigo and swirling nebulae. At the heart of the scene, a swirling vortex of black and purple represents dark matter, its tendrils stretching out, warping the surrounding fabric of spacetime. Tiny, bright stars twinkle in the distance, illuminating the darkness. In the foreground, a lone astronomer gazes up at the sky, their silhouette silhouetted against the swirling vortex, holding a telescope that points directly at the dark matter. The scene evokes a sense of awe and mystery, highlighting the invisible forces that shape our universe. Rendered in a painterly style, with a soft, ethereal glow, the image should convey the beauty and mystery of dark matter.

Though it makes around 27% of the cosmos invisible, dark matter affects cosmic gravity and remains one of the biggest riddle in physics. From gravitational lensing to galactic rotation curves, this page travels across the evidence of its existence. One night at an observatory, where astronomers discussed how dark matter forms the universe, my interest ...
