[Intro]
Impossible?
(Theoretically possible)
[Verse 1]
Would you like to go
(On a trip both far and near)
Exploring what we know
(And what’s to fear)
[Bridge]
Impossible?
(Theoretically possible)
[Chorus]
Into the future
(Let’s ride)
An endeavor
(End? …nevermore)
[Verse 2]
Yow would come to know
(The physics… and quick)
The speed of light we go
(Better bring some music)
[Bridge]
Impossible?
(Theoretically possible)
[Chorus]
Into the future
(Let’s ride)
An endeavor
(End? …nevermore)
[Outro]
Speed and gravity
(Indeed gain clarity)
How fast can we go
(Guess it’s time we know)
ABOUT THE SONG
In physics, time travel into the future is not only theoretically possible but a well-established and measured phenomenon known as time dilation. According to Albert Einstein’s theories of relativity, the rate at which time passes is relative and can change depending on speed and gravity.
Primary Mechanisms of Future Time Travel
Physicists have identified two main ways to “jump” into the future by slowing down your own internal clock relative to the rest of the world:
* Velocity-Based Time Dilation (Special Relativity): The faster you move through space, the slower you move through time.
* The Effect: If you were to travel on a spaceship at near-light speeds (e.g., 99.9% the speed of light) for what felt like one year to you, several decades might have passed on Earth when you returned.
* Real-World Example: Astronauts on the International Space Station (ISS) travel at 17,500 mph. After six months, they have aged approximately 0.005 seconds less than people on Earth.
Gravitational Time Dilation (General Relativity): Time passes more slowly in stronger gravitational fields.
* The Effect: Clocks near massive objects (like stars or black holes) run slower than clocks in deep space.
* Extreme Scenarios: A person who orbits the edge of a massive black hole for a few hours might return to Earth to find 1,000 years have passed.
* Daily Technology: GPS satellites are farther from Earth’s gravity than we are, causing their clocks to run about 38 microseconds faster per day than clocks on the ground. Engineers must constantly correct for this “time travel” to keep GPS accurate.
Comparison with Past Time Travel
While traveling to the future is a standard consequence of modern physics, traveling into the past is far more controversial. Theories like “wormholes” or “closed timelike curves” suggest it might be mathematically possible, but many physicists, including the late Stephen Hawking, argue that the laws of nature likely prevent it to avoid causality paradoxes (like the “grandfather paradox”).
