so I would like to start off today by first asking you to close your eyes so

first asking you to close your eyes so

first asking you to close your eyes so imagine yourself deep in outer space you

imagine yourself deep in outer space you

imagine yourself deep in outer space you are thousands of light-years away from

are thousands of light-years away from

are thousands of light-years away from here you’re in a place where time runs

here you’re in a place where time runs

here you’re in a place where time runs in slow motion so you see galaxies

in slow motion so you see galaxies

in slow motion so you see galaxies merging and stars exploding as the rest

merging and stars exploding as the rest

merging and stars exploding as the rest of the universe is running in

of the universe is running in

of the universe is running in fast-forwarding you’re in a place where

fast-forwarding you’re in a place where

fast-forwarding you’re in a place where gravitational forces are so strong that

gravitational forces are so strong that

gravitational forces are so strong that even the tiniest of the human cells are

even the tiniest of the human cells are

even the tiniest of the human cells are stretched and shredded into thee he can

stretched and shredded into thee he can open eyes hear what I described to you

open eyes hear what I described to you

open eyes hear what I described to you are just a few of the many bizarre and

are just a few of the many bizarre and

are just a few of the many bizarre and fascinating things that happen near a

fascinating things that happen near a

fascinating things that happen near a black hole

black hole

black hole my name is near spatula I’m an

my name is near spatula I’m an

my name is near spatula I’m an astronomer at MIT that I find black

astronomer at MIT that I find black

astronomer at MIT that I find black holes and today I’m gonna tell you how

holes and today I’m gonna tell you how

holes and today I’m gonna tell you how we astronomers find bladders a black

we astronomers find bladders a black

we astronomers find bladders a black hole is a region in space inside rifts

the Faculty of this vision is known as the event horizon conceptually you can

the event horizon conceptually you can

the event horizon conceptually you can understand what a black hole is by

understand what a black hole is by

understand what a black hole is by thinking about Earth’s gravity

thinking about Earth’s gravity

thinking about Earth’s gravity Earth’s gravity is what is called it’s

Earth’s gravity is what is called it’s

Earth’s gravity is what is called it’s equality to your chairs right there

equality to your chairs right there but imagine putting on a jetpack and

but imagine putting on a jetpack and

but imagine putting on a jetpack and launching yourself vertically upwards at

launching yourself vertically upwards at

launching yourself vertically upwards at 40,000 kilometers grab with that kind of

40,000 kilometers grab with that kind of

40,000 kilometers grab with that kind of speed you will be able to escape Earth’s

speed you will be able to escape Earth’s

speed you will be able to escape Earth’s gravity and venture out into space as

gravity and venture out into space as

gravity and venture out into space as far as you want and you slower than this

far as you want and you slower than this

far as you want and you slower than this you like to fall back down to earth or

you like to fall back down to earth or

you like to fall back down to earth or get trapped in orbit around Earth so

get trapped in orbit around Earth so

get trapped in orbit around Earth so let’s compress earth by a factor of

let’s compress earth by a factor of

let’s compress earth by a factor of 10,000 by keeping the massive earth is

10,000 by keeping the massive earth is

10,000 by keeping the massive earth is not roughly one kilometer in diameter

not roughly one kilometer in diameter

not roughly one kilometer in diameter the gravity in the surface of this earth

the gravity in the surface of this earth

the gravity in the surface of this earth is now hundred million times stronger

is now hundred million times stronger

is now hundred million times stronger than usual in order to get off desert

than usual in order to get off desert

than usual in order to get off desert you have to launch yourself

you have to launch yourself

you have to launch yourself at four million kilometers per hour

at four million kilometers per hour

at four million kilometers per hour that’s a factor of 100 times faster than

that’s a factor of 100 times faster than

that’s a factor of 100 times faster than this work now let’s take this a step

this work now let’s take this a step

this work now let’s take this a step further and compressed earth down to the

further and compressed earth down to the

further and compressed earth down to the size of a metal ball is being passed

size of a metal ball is being passed

size of a metal ball is being passed around only one centimeter in diameter

around only one centimeter in diameter

around only one centimeter in diameter earth is now the size of typical

earth is now the size of typical

earth is now the size of typical blueberry the grab be inside this

it will turn into a black hole in order

it will turn into a black hole in order to get off this earth you have to launch

to get off this earth you have to launch

to get off this earth you have to launch yourself at greater than the speed of

yourself at greater than the speed of

yourself at greater than the speed of light but that is not possible because

light but that is not possible because

light but that is not possible because Einstein theory of relativity tells us

Einstein theory of relativity tells us

Einstein theory of relativity tells us that nothing can go faster than the

that nothing can go faster than the

that nothing can go faster than the speed of light so that means your stuff

speed of light so that means your stuff

speed of light so that means your stuff no matter what you do you will not be

no matter what you do you will not be

no matter what you do you will not be able to get off this new very sensor but
