- Who is the Cosmology poster for?
- Cosmology 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 Cosmology poster?
- Space itself expands. Galaxies are not moving through space away from us. A wall chart earns its place by being glanceable from where the work is happening, so Cosmology belongs on the wall where that physical science work actually happens, within glancing distance, rather than filed away.
- What other posters go with Cosmology?
- Black Holes, General Relativity and Gravitational Time Dilation sit alongside Cosmology 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 HolesGeneral RelativityGravitational Time Dilation
- Is the Cosmology poster free to download and print?
- Yes. Cosmology 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 Cosmology poster print at?
- Cosmology 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 Cosmology loses nothing.Printing guide
