A light year is the distance covered by light in a year. So a light year is greatest when the speed of light is greatest: that is, in vacuum. However, since much of outer space is near vacuum, a light year is near enough a constant measure.
light years? :P
9 times greater.
The parallax effect becomes unnoticeable after 1,000 light years.
Violet light has greater energy because it has higher frequency than yellow light
A light year is about 63,000 times greater than an astronomical unit.
Light travels slower in a material with greater optical density.
You become younger by donating to the temple of light with i think $50,000 and then then the monks will take away 5 years of your age. But you can only do this once.
You have to flip the inequality sign. If it is less than(<) it has to become greater than(>). If it is greater than(>), it has to become less than(<). If it is less than equal to(<=), it has to become greater than equal to(>=). If it is greater than equal to(>=)., it must become less than equal to(<=).
Three decades is 30 years, so obviously 33 years is greater.
5 decades equals 50 years which is greater than 48 years
Numbers become greater proceeding to the right.
Exoplanets are located outside our solar system, so their distances can vary widely. The closest known exoplanet to Earth is Proxima Centauri b, which is about 4.24 light-years away. However, some exoplanets have been discovered at much greater distances, hundreds or even thousands of light-years away.
