Is Space Infinite?
Theories about size of space. Have people estimated different sizes? What have they based their predictions on? How would we then prove or disprove their ideas?
-
Our Milky Way is 150,000 to 100,000 light years across
There are more stars in the universe than grains of sand on all the beaches on Earth. That’s at least a billion trillion.
-
The observable universe is around 93 billion light years across one of the interesting things about the universe is that it is currently expanding
-
What technology has been sent into space? You could also ask how far have probes travelled? What data have they collected? Could they go further? Are there any planned missions?
Where is technology documented? You could add in NASA images, mission reviews etc
Current Estimates? you could consider discussing the ways we would travel to the edge of the solar system / universes / galaxies.

How is space categorised? I think you probably need to discuss the definitions of areas of space too. This links into your yellow arm. What is a solar system, galaxy and universe? Maybe since space is 3D could you consider the idea of a 4D or a multiverse?
