For your grandson who likes cosmology, here are some ideas:
1. A telescope - this can help your grandson explore the stars and the world beyond.
2. A book on cosmology - get him a book that explores the wonders of the universe, with illustrations and explanations to help him understand further.
3. A telescope smartphone adapter - this can allow your grandson to take pictures of celestial bodies with his phone.
4. A poster or wall art - find a high-quality poster depicting astronomy or cosmology, something he can hang over his bed or study desk.
5. A planetarium projector or virtual reality headset - this can give him the experience of being in space, virtually exploring the universe.
All of these ideas should be fun for your grandson and can help him learn more about cosmology.
Or you can get him a star map with the date when he was born.
