The sun warms up our planet but space is cold. If I lit a candle and stood 20 feet away, I could see the light but not feel the warmth. So, why do we feel warmth from the sun but space isn’t warmed by it?
It’s both. Depends if you’re in direct sunlight or not. In the near-vacuum of space, there’s very little to be warmed by the Sun. Space itself acts more as an insulator than a source of hot or cold.
