What are black holes?

A black hole is a area in space where a pull of gravity is so strong, nothing can escape from it

Meanings

Gravity: gravity pulls us on the ground, it it weren't for gravity we would be flouting in the air.

Speed of light: this is the meaning of some really fast light that nothing can catch up to.

Hydrogen: a colorless, odorless, flammable gas that combines chemically with oxygen to form water: the lightest of the known elements. Symbol:H; atomic weight: 1.00797; atomic number: 1; density: 0.0899 g/l at 0°C and 760 mm pressure.Collapsing: falling

Universe: this is where we are living

Galaxy: The galaxy contains earth that mean it is containing us

Hubble Space Telescope: is a telescope that can look super far

Astronomer: an expert in astronomy; a scientific observer of the celestial bodies an expert in astronomy; a scientific observer of the celestial bodies

Facts!!!

1. Black Hole Facts. Black holes are among the strangest things in the universe.
2. They are massive objects – collections of mass – with gravity so strong that nothing can escape, not even light.
3. The most common types of black holes are the stellar-mass and supermassive black holes
4. The massive gravitational influence of a black hole distorts space and time in the near neighbourhood. The closer you get to a black hole, the slower time runs. Material that gets too close to a black hole gets sucked in and can never escape.
5. Material spirals into a black hole through an accretion disk — a disk of gas, dust, stars and planets that fall into orbit the black hole.
6. The “point of no return” around a black hole is called the “event horizon”. This is the region where the gravity of the black hole overcomes the momentum of material spinning around it in the accretion disk. Once something crosses the event horizon, it is lost to the pull of the black hole.
7. Black holes were first proposed to exist in the 18th century, but remained a mathematical curiosity until the first candidate black hole was found in 1964. It was called Cygnus X-1, an x-ray source in the constellation Cygnus.
8. Black holes do not emit radiation on their own. They are detected by the radiation given off as material is heated in the accretion disk, and also by the black hole’s gravitational effect on other nearby objects (or light passing by.

Application B

Poem time

Black holes will suck up our  North pole,

Which is not a good troll.

You get stuck in its soul,

And that’s its goal.

The hubble telescope can see so far,

It could even see a star.

There is no way you can escape,

From a hole darker than a grape.

Nothing can travel the speed of light,

It swoops away out of sight.

Let’s do something so this girl doesn't get sucked into black hole

!!!!!Did it!!!!!

Now I am going to write a sentence about what will happen when a black hole was forming:

If a black hole slowly appears I would ask a scientist to make a  portal to teleport as much people as possible and send us to a different milky way

Hope You Enjoyed!
