Black Hole Story

What is a Black Hole?

A black hole is a region of spacetime where gravity is so strong that nothing, including light and other electromagnetic waves, has enough energy to escape it. 

Extreme Mass

These black holes are very tiny but have the mass of a large mountain. (Mass is the amount of matter, or “stuff,” in an object.) A  kind of black hole is called “stellar.” Its mass can be up to 20 times more than the mass of the Sun.

There are four types of black holes: stellar, intermediate, supermassive, and miniature.

What if you land in Black Hole

If you land  heroically into a stellar-mass black hole, your body would be subjected to a process called 'spaghettification'. . The black hole's gravity force would compress you from top to toe, while stretching you at the same time… thus, spaghetti.

Milky Way Galaxy - Sagittarius A*'

Astronomers estimate that the Milky Way has anywhere from 10 million to 1 billion stellar black holes,

Sagittarius A* (, abbreviated Sgr A*), is the supermassive black hole at the Galactic Center of the Milky Way.


Chance of encontering a black hole

Given how many black holes we expect are out there and how long our Solar System has been around, that's only about a ~0.000000001% chance, or 1-in-100 billion, that any planet would encounter a black hole over the past 4.5 billion years.

Sixth Sense

Sixth Senses  Sixth sense (ESP extra sensory perception)is a power of perception beyond the five senses.  It is an inner sense of guidance that can help you navigate your way through life, to better relationships, health, well-being, and success. It is a cumulative power of all your other senses - sight, sound, taste, touch, smell - that culminates in a stronger sense of inner knowing.

Neurodivergence -  Mental illness or Mad Scientist? Who Is Neurodiverse/Neurotypical? The terms "neurodivergent" and "neurodiverse" refer to people whose thought patterns, behaviors, or learning styles fall outside of what is considered "normal," or neurotypical of humans. The concept of neurodiversity is not necessarily disabilities. Some differences can be real strengths. Who are Neurodivergent? The neurodiverse population includes people with specific diagnoses that are considered developmental disorders (as opposed to intellectual disabilities or mental illnesses). These include but are not limited to: Autism : A developmental disorder that includes differences in social communication skills, fine and gross motor skills, speech, and more Attention deficit hyperactivity disorder ( ADHD ): A neurodevelopmental disorder that includes features of inattention, hyperactivity, and impulsivity Tourette's syndrome : A tic disorder that starts in childhood ...
