El astrofísico Neil deGrasse Tyson lo resume con datos que no admiten mucha discusión:
En la época de las cavernas, un ser humano vivía en promedio 30 años. Para 1840, la esperanza de vida apenas había subido a 35. Y eso que todo era “orgánico”: aire puro, agua sin procesar y animales de libre pastoreo.
Aun así, la gente moría joven.
Lo que realmente disparó la expectativa de vida no fue la “vida natural”, sino la ciencia: vacunas, antibióticos, saneamiento, tecnología médica y conocimiento acumulado.
Por eso las expectativas razonables deben alinearse con lo que muestra la evidencia científica.
Y si algo enseña la historia es esto: cada vez que confiamos en la evidencia, avanzamos; cada vez que la ignoramos, retrocedemos.

Perspective is everything when observing the cosmos.
The phases of the moon aren't caused by the Earth's shadow, but by our shifting vantage point of the lunar surface as it orbits our planet.
It's a continuous, 29.5-day cosmic dance of light and geometry; a profound reminder that half the moon is always bathed in sunlight, we just happen to be watching the transition.

Artemis Mission Route in 3D
- This animation visualizes the Artemis mission trajectory in a dynamic 3D perspective, showing how the spacecraft travels through the Earth–Moon system while all celestial bodies are in motion. Instead of a static path, the Sun, Earth, and Moon move simultaneously, revealing the true complexity of orbital mechanics. The result highlights how the Artemis route is not a simple curve, but a constantly shifting trajectory shaped by gravity and motion. This view provides a clearer understanding of how modern space missions navigate through space in real time. Right now, Artemis is on its return path to Earth and is expected to arrive back soon as it completes its mission. The sizes and distances of the Sun, Earth, and Moon are not to scale and are adjusted for visual purposes.
