When Actually Are You?

how long is

now there is a legend among the more

advanced civilizations of the universe

one whispered quietly passed down

through the

generations the story of the star

whale a formidable creature that can

open its Cosmic mouth and swallow solar

systems whole in a single gulp one flick

of its Mighty fluke can lay waste to

entire civilization

the oldest libraries in the cosmos hold

the most ancient of books all with

drawings of this Leviathan pieced

together from rumor and

heay its leathery skin is said to be

encrusted with Barnacles of star stuff

it's enormous baline plates peppered

with billions of years worth of

interplanetary

Plankton at least that is billions of

years to us for the star whale travels

at as close to the speed of light as it

is possible for an object with mass to

get to it time passes very differently

indeed making our sense of now a

nonsense to the star whale all 13.8

billion years of the universe's history

unfolds in a single quintilian of a

second the entirety of human history

happens in far less not even noticeable

to its senses every war every invention

every lost love and every laughing child

gone in no time at

[Music]

all and as we'll see as we follow the

story of this great creature the notion

of now is not only highly mysterious but

also wildly subjective and you don't

need to be a giant Intergalactic whale

to have an altered perception of

[Music]

it a car races down a road towards a

flock of pigeons seemingly oblivious to

the oncoming danger it looks through all

the world like the birds will become one

with the tarmac only for them to scatter

at the very last moment why did they

leave it so

long the truth is they didn't our sense

of now when theirs is different pigeons

experience the world at over 100 frames

per second as opposed to the 25 to 30

that films do it helps them keep track

of fast moving insects so in the case of

the onrushing car they simply have more

time to react to it than it naively

seems to you or I they experience the

world in slow

motion and so now can last longer or

shorter depending on how you have

evolved what you are doing and like the

star whale in the most extreme cases how

fast you are

traveling indeed it is even possible for

two people to see a series of Nows

unfold in a completely different order

human intuition is no yard stick for the

way the universe really

works and so as we journey with the star

whale into the far distant Universe Giga

anoms passing in the blink of an eye we

are left with one big question what is

now and does it even exist outside of

our

heads

YouTube what does space taste

like stars swirl in the void at dizzying

speeds as the very fabric of time and

space is tugged and stretched we are in

the shadow of Sagittarius AAR the

monstrous black hole at the heart of our

Milky Way galaxy just 390 light years

away from this dark heart an

astronomical footstep lies a vast cloud

of gas and dust known as Sagittarius B2

it's been the subject of much scr

with astronomers pouring over its

Ancient Light In Search for Clues to

what lies within among the many

ingredients they found there is a

molecule known as ethyl formate it may

sound unfamiliar but it's the same

molecule that gives raspberries their

distinctive flavor and so this begs the

question what does space taste like does

the star whale find some Celestial

snacks more delicious than others and

what about what space smells like well

ethyl formate is also responsible for

the smell of rum then there's the

kickstarter campaign that's raised over

half a million dollars to manufacture

odor space a perfume based on astronauts

accounts of the universe's distinctive

odor think burnt meat burnt cakes spent

gunpowder and the welding of

metal but whatever the star whales

culinary preference is it's still Bound

senses help you interpret the world

such as salty sweet sour bitter and

then passes them onto a part of your

brain called the thalamus next they are

shuffled to a small region right in the

middle of your brain known as the gustat

are carefully decoded like a spy pouring
