The universe is everything, It even includes time itself and, of course, it includes you..
Here are a few that come to mind:
- The International Space Station is the third brightest object in the sky after the Sun and the Moon.
- A full Moon is 9-10 time brighter than a half Moon due to the Lunar regolith having retroreflective properties.
- Due to the effects of time dilation, if you had a spacecraft that could continuously accelerate at 1G indefinitely, you could cross the entire Milky Way in about 12 years despite traveling about 100,000 light years
- You cant reach speed of light. But you can come damn close like 99,9999%. And anything beyond 99% starts to slow your time exponentially. But also increases energy required to accelerate exponentially too
- J1047B is a ringed planet orbiting V1400 Centauri. What is interesting about this planet is that its ring system is approximately 640x larger than Saturn’s. If J1047B was where Saturn is in our Solar System, it would dominate our sky (please google how it would look, it’s amazing :))
