Story of our Universe in 1 minute - Science Loop

The time-lapse of the entire universe is pretty interesting. "How did it begin" is an interesting question. "How vast is our universe" is also puzzling. The Story of our Great Universe is here in 1 minute. The visuals are pretty exciting.

See the extreme Timelapse of the evolution of Universe. The video compressed the Entire Timeline Of universe (13.8 B Years ) in a Minute scale. From the Big-Bang to Present. Primordial clouds to Our Sun. Supernova Explosion and formation of the Black-hole. Collision to exciting Formation. And the  Rise of life. The visual images put together are pretty exciting in : Time-Lapse of the Entire Universe. This video is: Extream Animation, VFX, SFX. Use Headphones for a really better Experience.

How did the universe start? There are theories out there. The Big Bang theory is a cosmological model of the observable universe from the so-called earliest known periods through its subsequent large-scale evolution. The model describes how the universe expanded from an initial state of high density and temperature, and offers a comprehensive interesting deep explanation for a broad range of observed phenomena, including the abundance of light elements, the cosmic microwave background (CMB) radiation, and large-scale structure.

Crucially, the theory is compatible with Hubble-LemaƮtre law - the certain observation that the farther away galaxies are, the faster they are moving away from Earth. Extrapolating this cosmic expansion backwards in time using the known laws of physics, the theory describes a high density state preceded by a singularity in which space and time lose meaning. There is certainly no evidence of any phenomena prior to the singularity. Detailed measurements of the so-called expansion rate of the universe place the Big Bang at around 13.8 billion years ago, which is thus considered the age of the universe.

First Space Hurricane Discovered : Science Loop

This is pretty interesting - the first-ever (first ever that was observed by humans) 'space hurricane' was detected over the North Pole. For the first time, astronomers have detected a powerful, 600-mile-wide (1,000 kilometers) hurricane of plasma in Earth's upper atmosphere - a phenomenon they're calling a "space hurricane." The space hurricane certainly raged for nearly 8 hours on Aug. 20, 2014. This fascinating phenomenon behaved similarly to the wind-based hurricanes we find on Earth, but this space version rained electrons instead of water. It seems that any planet with plasma and a magnetic field could have these 'violent' space storms, researchers said.

The hurricane seems to be formed from a tangled mess of magnetic field lines and fast-flying solar wind. The hurricane was invisible to the naked eye. However, 4 weather satellites that passed over the North Pole detected a formation not unlike a typical terrestrial hurricane. The intense space hurricane was shaped like a funnel with a quiet "eye" at the center. It was surrounded by several counterclockwise-spinning spiral arms of plasma (ionized gas found all over the solar system, including in Earth's atmosphere).

Usually, the "eye of the storm" is a region of mostly calm weather at the center of tropical cyclones. The eye of a storm is a roughly circular area, typically 30-65 kilometers in diameter. It is surrounded by the eyewall, a ring of towering massive thunderstorms where the most severe weather and highest winds certainly occur.

Until this important space discovery, it was uncertain if space plasma hurricanes existed. The existence was proved with this striking observation. These space hurricanes must be created by unusually large and fast transfer of solar wind energy and charged particles into the Earth's upper atmosphere.

Plasma and magnetic fields in the atmosphere of planets certainly exist throughout the universe, so the findings suggest space hurricanes should be a widespread phenomena.

This science phenomenon was discovered by a team of researchers from Shandong University in China. They had observed the storm over the Arctic region on 20 August 2014, before identifying its nature in 2021. The research team also consisted of scientists from the United States, the United Kingdom, and Norway. The team observed the space hurricane for 8 hours, before it gradually broke down. The storm was observed during a certain period of low solar and geomagnetic activity.
