If the moon were only 1 pixel: A tediously accurate solar system model (2014) (joshworth.com)

Article summary

The article presents a tediously accurate solar system model where the moon is only 1 pixel, allowing for a unique perspective on the scale of the solar system. The model uses horizontal scrolling to display the vast distances between celestial bodies. The article also links to various translations and previous discussions on the topic. The model provides an interactive way to explore the solar system's scale.

Main themes

• scale of the solar system
• interstellar travel
• relativity and time dilation
• technological challenges
• cosmology and universal expansion
• theoretical physics and faster-than-light travel

What commenters say

• Traveling at a significant fraction of the speed of light could make interstellar travel possible within a human lifetime, but it would require immense energy and technological advancements.
• The universe's vast scale and the speed of light make it difficult for humans to explore and communicate with other star systems.
• Some commenters argue that faster-than-light travel is impossible according to current understanding of physics, while others suggest that it may be possible with new discoveries or technologies.
• The effects of time dilation and relativity would be significant for travelers approaching the speed of light, but the experience would be normal for the traveler themselves.
• The risk of colliding with small meteorites or dust particles at relativistic speeds is a concern, but the likelihood is difficult to estimate due to the vastness of space.
• The technological challenges of building a rocket capable of accelerating to significant fractions of the speed of light are significant, and may be insurmountable with current technology.
• Alternative approaches, such as manipulating the trajectory of the sun or using exotic propulsion methods, may be more feasible than high-speed travel.
• The expansion of the universe means that even if travel at a significant fraction of the speed of light were possible, the destination would be moving away from the starting point, making travel even more challenging.
