A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying.

Because no light can get out, people can't see black holes. They are invisible. Space telescopes with special tools can help find black holes. The special tools can see how stars that are very close to black holes act differently than other stars.

How Big Are Black Holes?
Black holes can be big or small. Scientists think the smallest black holes are as small as just one atom. 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.

Another kind of black hole is called "stellar." Its mass can be up to 20 times more than the mass of the sun. There may be many, many stellar mass black holes in Earth's galaxy. Earth's galaxy is called the Milky Way.

The largest black holes are called "supermassive." These black holes have masses that are more than 1 million suns together. Scientists have found proof that every large galaxy contains a supermassive black hole at its center. The supermassive black hole at the center of the Milky Way galaxy is called Sagittarius A. It has a mass equal to about 4 million suns and would fit inside a very large ball that could hold a few million Earths.

How Do Black Holes Form?
Scientists think the smallest black holes formed when the universe began.

Stellar black holes are made when the center of a very big star falls in upon itself, or collapses. When this happens, it causes a supernova. A supernova is an exploding star that blasts part of the star into space.

Scientists think supermassive black holes were made at the same time as the galaxy they are in.

If Black Holes Are "Black," How Do Scientists Know They Are There?
A black hole can not be seen because strong gravity pulls all of the light into the middle of the black hole. But scientists can see how the strong gravity affects the stars and gas around the black hole. Scientists can study stars to find out if they are flying around, or orbiting, a black hole.

When a black hole and a star are close together, high-energy light is made. This kind of light can not be seen with human eyes. Scientists use satellites and telescopes in space to see the high-energy light.

Could a Black Hole Destroy Earth?
Black holes do not go around in space eating stars, moons and planets. Earth will not fall into a black hole because no black hole is close enough to the solar system for Earth to do that.

Even if a black hole the same mass as the sun were to take the place of the sun, Earth still would not fall in. The black hole would have the same gravity as the sun. Earth and the other planets would orbit the black hole as they orbit the sun now.

The sun will never turn into a black hole. The sun is not a big enough star to make a black hole.

How Is NASA Studying Black Holes?
NASA is using satellites and telescopes that are traveling in space to learn more about black holes. These spacecraft help scientists answer questions about the universe.

black hole
noun
ASTRONOMY
  1. a region of space having a gravitational field so intense that no matter or radiation can escape.
    • informal
      a place where people or things, especially money, disappear without trace.
      "the moribund economy has been a black hole for federal funds"
 
Alliens walikua wana shughuli hapo na NASA wakataka kujua ikawa balaa.Haya mi njaa inauma nitarudi jumamosi
 
DEFN: a region in space where gravity is so strong that nothing, not even light, can escape (from cambridge dictionary),
It is a center of a galaxy
 
It means all effects of gravitational force comes from the black hole? What will happen if the space station bounce on it? How do they even know that black hole exist?
Nevertheless what is the relationship between Planet X and Black hole?

Wadau wengine wote wataishia kukopi na kupest toka mitandao mingine kwa lugha ya kingereza.
 
Mkuu baada ya mlipuko wa Star yani nyota unaujulikana kama supernova basi black hole hutokea hutokea na the more star zinakufa hupoteza speed na kuvutwa na blackhole hivo black hole huzidi kuvuta died star na kuzikandamiza na kuwa kitu kidogo but very massive na kunakuwa na Gravity kubwa kana kwamba hata mwanga hauwezi kupita hapo ktk blackhole Kuna taasisi ya LIGO juzi juzi ilitangaza kudetect Gravational waves alizo detect Einstein miaka mia iliyopita Ugunduzi huo utafuta mipaka na ya uchunguzi wa universe yetu kila star huwa ina rotates ktk orbit ya blackhole ktk milkway kuna blackhole kati na star zinaizunguka hio blackhole

Ndg, naona watu wanatoa maana kwa kunakili maelezo ya wana sayansi katika vitabu vyao juu ya kile wanachodhani wamekielewa.Hakuna anaeleza hili TUNDU JEUSI ni kitu gani NJE YA DHANA ya wanaojaribu kutaka kujua wakijiita wanasayansi wa anga za juu.

Huhitaji kukariri, unatakiwa ujue. Hizo definitions ndizo zilizotudumaza tukaua udadisi wetu WAASILI kwa kupitia DNA za watu WEUSI (Kumbuka DNA is a Store House of Knowledge,) wala huhitaji kukaa darasa la wazungu kujua, bali ni kuua Subconscious mind zetu kwa canotation meaning za lugha zao.
Kitu cha kuDADISI HAPA NI KWANINI wamesema BLACK HOLE na sio WHITE HOLE. KUMBUKENI BLACKNESS IS THE SOURCE OF LIFE: Nilishawai kuchambua hili kwenye mijadala mingi tu humu JF. Lakini kwa faida ya wengine ngoja nirudie tena.

BLACK IS NOT A COLOUR, IS NOT ISM OR ISKISM, IS NOT A RELIGION AND IT HAS NOTHING TO DO WITH POLITICS.
BLACK IS A SOURCE FROM ONCE ALL COLORS COME, BLACK IS THE NATURE THAT HOLDS ALL LIFE FORM IN ITS WOMB.
THERE IS NOTHING BEFORE IT AND THERE IS NOTHING AFTER IT, EVERYTHING IS IN IT. ALL COLORS COMES OUT OF BLACK.

U CAN OVER-STAND EASILY THESE NATURAL FACTS, WHEN YOU START STUDYING YOURSELVES THROUGH "METAPHYSICS". IN ACTUAL FACTS, BLACK IS THE MOTHER NATURE.

Katika Bibilia Kitabu cha Mwanzo Sura ya 1 Mstari wa 1-4 unasema hivi:

1: In the beginning God created the heaven and the earth.
2: And the earth was without form, and void; and DARKNESS WAS UPON THE FACE OF THE DEEP. And the Spirit of God MOVED UPON THE FACE OF THE WATERS.
3: And God said, Let there be light: and there was light.
4: And God saw the light, that it was good: and God divided the light from the darkness.

So, FROM this story of creation we know that, DARKNESS (BLACKNESS) was there with GOD during CREATION. THAT MEANS, ALL THINGS CAME OUT OF/ FROM DARKNESS (BLACKNESS). Rejea Mstari wa 4 hapo juu KATIKA SURA HIO YA 1 KITABU CHA MWANZO, unasema God divided the LIGHT from the DARKNESS, sio God divided The DARKNESS from the LIGHT.

Sasa hapo juu nimesema Blackness is the source of all life form. Unaumbwa tumboni mwa mama kizani, Kifaranga kinatoka gizani kwenye YAI, Mbegu ili iote lazima izikwe gizani (Chini ya Ardhi) ndipo iweze kuota. Mimea inatengeneza chlorophyll kama chakula chake ambayo ni carbons (Blackness) yenye 6 protons, 6 Neutrons na 6 Electrones. Aina ya chakula tunachokula ni HYDROCARBONS au hydroblackness (WANGA, PROTEIN (AMINOACIDS), MAFUTA NA VITAMINS).

Na tunapata nguvu katika mwili sababu tuna black pigment (Melanin) ambayo ni kama ndio mafuta ya kuempower miili yetu, hivyo in black people no energy can escape, all energy sticks within, na UBONGO WETU ni kama UNIVERSE, NI WATER LIKE FLUID ambayo kwenye story ya UUMBAJI hapo juu unaona kuwa ROHO ya MUNGU ILIKAA katika Maji. BRAIN is the complex like milky way galaxy (universe).

Hivyo ili Life liwepo lazima kuwapo na DARK MATTER, DARK FORCE (Gravity), AIR (GASES), DARK ENERGY (Radiations) and H2O otherwise known as WATER na ndio maana Mungu akaumba viumbe vingi in nature ni BLACK, BROWN NA GREY. Ukiona kiumbe Cheupe kinatembea kimeumbwa maabara na ni dhaifu kwa kuwa hakiwezi kuabsorb dark energy zitasurvive vipi in Nature?.

Kwahio BLACK HOLE is where the CREATION starts and Ends. Because in nature, wherever there is Creation, there must be Destruction and Recreation. This is a life principle. Acheni kukariri definitions za watu wanaopenda kudumazaa akili za wengi ili wao wawe ndio maELITE.

SIRI ILIOKUBWA HAPA ULIMWENGUNI NI KWAMBA, MAARIFA YANAYOACHWA IN THE PUBLIC IS FULL OF LIES. WAKATI WAO WANAFAHAMU KIVINGINE.

Mfano: Ukisoma Geography kuanzia darasa la 4, unafundishwa kitu kinaitwa MISTARI ya Latitude na Longitude. na unafundishwa kuwa hii ni mistari iliyobuniwa. HAAAAAAHAHAAAAHAHA !!!!!!!!

In reality, the Latitudes and Longitudes are not imaginary Lines, these are actual force acting upon (Electromagnetic forces = Navigational Coordinates).
 
Katika moja kati ya physics ngumu kuelewa kwa layman ni hii.
All in all hizo zote ni theoretical physics za kina Hawking & co.

Ni kweli kuna thread nyingi ambazo Monstgala alielezea haya mambo kwa undani na uelewa mpana zaidi. New comers wa JF wangelikuwa wanatafuta hizi thread katika hili jukwaa, nafikiri wangelifaidika zaidi.
