Black Holes: Where infinity resides! The most strange and fascinating objects of outer space. MUSIC: Kevin MacLeod

What is a Black Hole? A Black hole can be defined as a large amount of matter packed into a very small space.



Think of a star hundred times larger than the sun squeezed into a space approximately the diameter of Pluto, which which gives rise to a gravitational pull so strong that nothing, not even light can escape.

Did you know our galaxy is covered in black holes? The one most probably to digest us and nearest to our solar system is still beyond 1600 light years.

The Discovery Black holes were predicted by Einstein in his theory of general relativity, which showed that when a star dies, it leaves behind a small, dense core.



The term was not coined until 1967 by John Wheeler and the first Black Hole was found in 1971.

Star's End: A Black Hole's Beginning A black hole comes into being when a star runs out of fuel and starts to collapse under its own gravity.

Singularity Singularity is the single point in space-time where all the mass of the black hole is concentrated.

Fun Fact If a person falls into a Black hole, theory has long suggested that he would be stretched out like a spaghetti, though his death would come only after reaching singularity but a study also found out that entering a black hole would cause instant death due to event horizon acting as a firewall.

Freezing of the objects To an observer with a telescope, an object passing the event horizon will appear to slow down then freeze without even seeming to pass through the event horizon.



This is because light cannot escape the black hole’s gravitational pull and light won’t reach the viewer for an infinitely long time.

Massive black holes at the center of galaxies It is now thought that most galaxies are held by super massive black holes at their centres, which hold together hundreds of solar systems.



Moreover, 30,000 light years away from Earth, at the centre of Milky Way galaxy, lies a black hole 30 million times the mass of our own sun.
