🎯 Space Travel Tips
Higher speeds mean shorter ship time but greater time dilation
Time dilation becomes significant above 50% light speed
Pack light! Resources scale with trip duration
Consider your family - they'll age differently!
This assumes constant velocity travel
Understanding Interstellar Travel Physics
Time Dilation Effects
When traveling at speeds close to the speed of light, time moves differently for you compared to people on Earth. This is Einstein's special relativity in action - time literally slows down for the traveler.
Why Exoplanet Travel is Challenging
- •Vast distances require years or decades of travel time
- •Resource requirements are enormous for long journeys
- •Relativistic effects create temporal disconnection
- •Current technology is nowhere near capable
Relativistic Formulas
γ = 1/√(1 - v²/c²)
t' = t/γ
- γ (gamma): Lorentz factor
- v: Velocity of spacecraft
- c: Speed of light
- t': Proper time (ship time)
- t: Coordinate time (Earth time)
Note: These calculations assume constant velocity travel and don't account for acceleration phases, which would be required in reality.
James Webb Space Telescope Discoveries
🔭 LHS 475b
The first exoplanet confirmed by JWST. Earth-sized and rocky, located 41 light years away in the constellation Octans.
💧 K2-18 b
A sub-Neptune with water vapor, CO₂, and methane detected. Located in the habitable zone of its red dwarf star.
🌍 TOI-715 b
A super-Earth 1.5 times Earth's size, orbiting in the conservative habitable zone of a nearby red dwarf.
