How do celebrities get social media handles with their names? Do companies like Twitter or Instagram assist celebs in getting a marketable handle? | [

Why does the sound of the explosion take almost 15 seconds delay to reach the guys on boat when it doesn't look that far away? (see comment for video link | [
"Light, or what you see when the volcano erupts, travels at 186,000 *miles per second*, while sound travels exponentially slower at about 767 *miles per hour*. It takes just a fraction of a millisecond for the light from the volcano to reach your eyes, as opposed tot he 15 seconds it takes the sound to reach your e... | [
"Usually it will not make a big difference. But if you were watching a movie, an explosion that occurred off screen to the left would sound like it came from the right, which might be momentarily confusing."

Why are advertisers still using click bait? | [
"It still works. There is an old saying that there is a sucker born every minute, and with the growing population that rate has increased."

What are they trying to accomplish at the LHC? How will this help humankind? | [

How do they get such incredible shots of animals in documentaries? | [
"They shoot A LOT of footage. Multiple guys shooting, multiple cameras, over the course of a long time. They have to comb through it all, but they can edit it and use only the best."

"Those are indeed \"fake\". These extraordinary pictures of unborn baby animals inside their mother's womb (or in some cases, eggs) are fascinating, even if somewhat creepy.

Are humans the only animal that cries? If so, why? | [
"Most animals that are social have some behavior that indicates emotional or physical distress (such as your dog whining) but as far as we know the physical act of shedding tears for a purely emotional reason, and not due to irritation, appears to be a uniquely human way to express feeling a strong emotion.

Why does it take "2-6 weeks" to deliver goods purchased via TV but you could typically get it in less than half that time if you order online? | [

Siri's very good at understanding what I say, and yet Youtube's auto-generated subtitles are incredibly wrong. How so ? | [

why do humans perceive time at the 'rate' that we do? Does time even have a natural 'rate', or is it just a property of consciousness and our perception? | [
"Perception of time is relative. If you ever get into a car accident or other life-or-death scenario, you will know what I mean.
