Gravitational lensing is an observed phenomenon. Can one have a gravitational mirror?
A slightly unrelated question: Can gravitational waves be reflected?
You can get these on amazon but no way of getting other vehicles that are made to the same scale, I resorted to drawing them for my daughter, so she could appreciate the size of Saturn V compared to the rest.
agreed, great idea. at the moment you have to build your own or buy some kit from an oldy worldy website. not ideal – not sure why nobody just makes and sells these for schools, they could be as standard as plastic toy cars or geometric shapes.
Gravitational lensing could be the way forward, now that we know most of the universe isn’t visible to us, yet.
“In this video we explore a design for what would be the largest telescope humanity will ever use. It would allow us to take images of an exoplanet from over 100 light years away at better resolution than hubble is able to see mars from earth. The proposed FOCAL spacecraft uses a weird property of space called gravitational lensing to bend light around the sun as if it was a giant lens.”
Not a new idea but an interesting one. Been discussed on stack exchange / physics for a while, here is a thread.
Its possible to use gravity as a lens, they should be possible to use it as a mirror also. Nice idea.
there are a few options for this already. see https://www.skyatnightmagazine.com/top-astronomy-kit/best-gadgets-turn-smartphone-into-astrophotography-camera/
Wow, can’t believe these already exist and less than 50 pounds. Are they any good?

Great idea that others are working on
