tinelmis What is Planck Time? Planck Time is the smallest possible unit of time in the universe, named after the physicist Max Planck. It is defined as the time it takes for light to travel the Planck length in a vacuum, which is approximately 5.39 x 10^-44 seconds. At this scale, the laws of physics as … Read more
I. What is Navajo Starlore? Navajo Starlore is the traditional astronomical knowledge and beliefs of the Navajo people, an indigenous tribe in the southwestern United States. It encompasses a rich tapestry of stories, myths, and practical knowledge related to the stars, constellations, and celestial bodies. For the Navajo people, the stars are not just distant … Read more
What is Flux Density? Flux density is a measure of the amount of energy passing through a given area in a specific amount of time. In simpler terms, it is the amount of energy per unit area. Flux density is commonly used in various fields such as physics, engineering, and astronomy to quantify the amount … Read more
I. What is a Cosmic Ray Shower? Cosmic rays are high-energy particles that originate from outer space. When these particles enter Earth’s atmosphere, they interact with the atoms and molecules in the air, creating a cascade of secondary particles known as a cosmic ray shower. These showers can contain a vast number of particles, ranging … Read more
I. What is microgravity? Microgravity, also known as weightlessness, is the condition in which an object appears to be weightless due to the absence of gravitational forces. This phenomenon occurs when an object is in free fall or orbiting in space, where the gravitational pull is significantly reduced. In microgravity, objects float freely and do … Read more
I. What is the Carrington Event? The Carrington Event, also known as the Carrington Flare, was a powerful geomagnetic storm that occurred in September 1859. It was named after Richard Carrington, an English astronomer who observed a significant solar flare on the surface of the sun just before the event. The solar flare was so … Read more
I. What is the Big Bang Theory? The Big Bang Theory is the prevailing cosmological model for the observable universe from the earliest known periods through its subsequent large-scale evolution. It suggests that the universe began as a hot, dense state and has been expanding ever since. The theory is supported by a wide range … Read more
What is the Hubble Space Telescope? The Hubble Space Telescope, often referred to simply as Hubble, is a space telescope that was launched into orbit by NASA in 1990. It is named after the renowned astronomer Edwin Hubble and is one of the largest and most versatile telescopes ever built. Hubble’s primary mission is to … Read more
I. What is Galaxy Quenching? Galaxy quenching is a phenomenon in astrophysics where a galaxy stops forming new stars. This process is crucial in understanding the evolution of galaxies and the overall structure of the universe. When a galaxy undergoes quenching, it essentially halts its star formation activity, leading to a decrease in the number … Read more
I. What is the Thirty Meter Telescope (TMT)? The Thirty Meter Telescope (TMT) is a proposed extremely large telescope that is planned to be built on Mauna Kea, a dormant volcano in Hawaii. The TMT is designed to have a primary mirror that is 30 meters in diameter, which will allow it to gather more … Read more
