What’s on the Time Dilation poster
The rule, 3 worked examples, and the mistake everyone makes.
- A clock moving relative to an observer ticks slower by the Lorentz factor.
- Δt = γΔt₀
- Muons from the atmosphere = Reach the ground
- Atomic clocks flown around = Measurably behind
- GPS satellites = Corrected daily
- Common mistake: Asking which clock is really slow → Each observes the other's as slow
GPS would accumulate about 10 km of error per day without relativistic correction. This is engineering, not philosophy.

- Who is the Time Dilation poster for?
- Time Dilation belongs to the Physics section rather than to a school year, because physical science is not something one grade owns. Anyone learning relativity can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the Time Dilation poster?
- Not an illusion and not a clock fault. Time itself passes differently. A wall chart earns its place by being glanceable from where the work is happening, so Time Dilation belongs on the wall where that physical science work actually happens, within glancing distance, rather than filed away.
- What other posters go with Time Dilation?
- Black Holes, Cosmology and General Relativity sit alongside Time Dilation in the Physics section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Black HolesCosmologyGeneral Relativity
- Is the Time Dilation poster free to download and print?
- Yes. Time Dilation downloads as a free PDF with no account, no email and no watermark, like everything else in the Physics section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the Time Dilation poster print at?
- Time Dilation is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Time Dilation loses nothing.Printing guide
