letra de rapping about the theory of relativity - mac lethal

[verse 1]
last week on my youtube channel
i told my subscribers to pick the topic
i said i’d rap about anything
i got lots of answers
but the most popular answer i got was:
rap about the theory of relativity
okay
i’m gonna try to make this easy to explain
a lot of people treat this topic like a needle in their brain
they say, “oh my god this stuff is so confusing”
well let me fix that for you, baby
mac lethal is my name
okay, look
this is the universe
where everything happens
every moment, every action
every whole and every fraction
every person, every atom
every person that’s named adam
every galaxy, planet, star
every forwards, every backwards
the universe is made of sp-ce
sp-ce is like a fabric…
it’s empty
literally empty, it’s a vacuum
the universe is so big that it’s infinite
which means the universe is so big that you could never reach the end of it
but even if you could reach the end of it
it’s expanding so f-cking fast
that the future is a moment in the past
which means: we not only have questions that we don’t know how to answer
we have questions that we don’t know how to ask
now wait
don’t let that get confusing
just know that everything in existence is moving
it’s always been moving, it’ll always be moving
and time is a direction, a dimension, and illusion

[verse 2]
the theory of relativity
was created by albert einstein
but let me make something clear to you
when you talk about the theory of relativity
you’re not talking about only one theory
you’re talking about two:
there’s special relativity and general relativity
both of ’em are amazing
both of ’em need explaining
both of ’em sound like they were written in an alien language
so hold up, i’ma say it in laymen’s
special relativity has two main ideas
and i’ma break em down without complicated words
one: the law of physics applies to
every non-accelerating person, place, and thing in the universe
it doesn’t matter if you’re in a moving or a parked car
it doesn’t matter if it’s a planet or an actual star
as long as it’s moving at a constant speed
the laws of physics apply to it, indeed
and remember what i said?
everything is moving
according to the smartest person ever isaac newton
“bro, i’m not moving, i’m right here in one place”
“wrong. you’re on earth, and earth is moving through sp-ce”

[verse 3]
earth is moving relative to the sun and uh
the sun is moving relative to the earth and uh
they’re both moving relative to the galaxy
which is moving relative to the universe
now, idea two of special relativity states:
the speed of light always moves at the same speed
it don’t matter what source it’s from
it could be coming from an iphone, or coming from the sun
the light from this flashlight
and the light from this light sabre
move at the exact same speed
but depending on where you’re at in the universe…
and how fast you’re moving
you might see them differently

[verse 4]
this is general relativity:
let’s say time is a road paved with sp-ce
there’s no beginning or no ending
the speed of light is the speed limit
and the faster that you move on the road
the more the road starts bending
because the faster that an object moves
the bigger the object gets
the more it pushes sp-ce to slope downward
as time slows down and gravity gets more dense
that’s the reason earth revolves around the sun
the m-ss from the sun pushes down sp-ce-time
earth rides the curvature of the sun’s gravity
but if the sun was gone, earth would move in a straight line
so in conclusion: sp-ce is the same thing as time
they’re not separate, they’re intertwined
it’s a behaviour, an action
the movement of atoms
coordinates in the universe for which things happen
you can set two stopwatches to the same time
but gravity could make them both tick at different speeds
gps has to use relativity to work
it’s not a hypothesis it’s guaranteed

[outro]
okay, i’m gonna end the video now
this was a challenge to make — i learned a lot
i’m feeling proud
sometimes it’s not about the reason, why? or how?
it’s simply what the universe allows
