What is a White Hole?

Possible White Hole spotted?

A white hole is a hypothetical astronomical object that is the reverse of a black hole. While a black hole is known for its immense gravitational pull, which prevents anything, including light, from escaping its event horizon, a white hole is theorized to be a region of spacetime from which matter and energy can only emerge.

What are the Most Energetic Events in the Universe?

Astronomers catch fizzled-out gamma-ray burst from supernova

Here is a list of the most energetic events in the universe, arranged in order. Please note that the ordering of these events can vary depending on specific criteria used, such as total energy released, peak luminosity, or different types of radiation considered. The references provided should offer comprehensive information on each topic.

What Is Planck’s Constant?

What is a constant? In mathematics and science, a constant is a fixed value that remains unchanged throughout an equation, experiment, or mathematical operation. Constants are pivotal in providing stability and consistency to calculations and observations, playing a fundamental role in various fields of study.

Why do Nuclear Bombs Form Mushroom Clouds?

There have been historical accounts and depictions of massive explosions and cloud formations in various contexts that might resemble or be reminiscent of mushroom clouds that pre-date any nuclear explosions.

A mushroom cloud is a distinctive cloud-shaped formation that appears after the detonation of a nuclear bomb or a large-scale explosion. The cloud’s formation is the result of several factors, including the initial blast, the intense heat generated, and the subsequent rapid cooling and condensation of water vapor.

Correlation is Not Causation

“Correlation is not causation” is a critical concept in statistics and research methodology, reminding us that just because two variables are related does not necessarily mean that one causes the other.

Cosmic Inflation

Cosmic inflation is a theory of exponential expansion of space in the early universe, believed to have lasted from 1036 seconds to between 1033 and 1032 seconds after the Big Bang.

Inflation is a concept in cosmology that refers to a period of rapid expansion of the universe in its early stages. It is a theory proposed to explain several observed features of the universe, such as its overall homogeneity, isotropy, and the absence of certain types of relics.

Lots of Gold? Two Neutron Stars Colliding? What Happened?

A kilonova is an astronomical event that occurs when two neutron stars collide.

One of the most significant astronomical events in recent history occurred on August 17, 2017, when astronomers detected the collision of two neutron stars some 130 million light-years away.

What is a Globular Cluster?

To achieve the spatial distribution of stars in a Globular Cluster, as has been observed, a black hole fraction of 22% is necessary.

Globular clusters are fascinating astronomical objects composed of densely packed groups of stars. They are distinct from open clusters, which typically contain a few hundred stars, as globular clusters can host hundreds of thousands to millions of stars.

Rheology of Cats: Are cats liquid?

Can a cat be both a solid and a liquid?

Rheology is the branch of physics that studies the deformation and flow of matter. It applies to materials such as liquids, gases, and solids, and it plays an essential role in fields such as engineering, geology, and materials science. Rheological properties include viscosity, elasticity, plasticity, and viscoelasticity, which determine how a material responds to different stresses and strains.
