Black holes suck in light, so why are they black? | [
"We call them black because we believe that they suck in light and don't let it out. It's outgoing light we can see, you can't see light that's being absorbed only light that is being sent out or reflected."
] | [
"Black holes don't emit light. So by definition there is no way to see them directly. We observe them indirectly by seeing how the gravity of the black hole affects the objects around it that do emit light."

If something were to break the sound barrier in space, how would it differ from here on earth? | [
"The speed of sound depends on several variables even here on earth - humidity, air pressure, etc. Thus there is no \"speed of sound\" anywhere sound can't travel, such as in space."
] | [
"The sound of a sonic boom comes solely from the object breaking through the sound barrier. A bullet does the same thing, which is why a silencer doesn’t actually silence the whole thing. The bullet is still going to break through the sound barrier, and make a cracking sound. Any object that accelerates through the... | eli5_question_answer | {

How do they release HD movies that were out decades ago? | [
"Because the film originally used had higher resolution than the standard HD formats anyway. Quality 35mm film has a horizontal resolution of approximately [4096 pixels](_URL_1_), which is about twice the resolution (and four times the pixel count) of the [1080i/1080p](_URL_0_) HD format."

Where are the colors that a human can't see? Is my wall secretly another color? | [
