What ever happened to the Space Opera science fiction? | Viewers got a bit burned out on them, because there were a good number of them around for a while.

Why can't we build a massive building with an elevator that takes you into space? | Hey dude! In short, it's because we're limited by the strength of materials that, well, exist. In long, there are a bunch of reasons why we really can't do it! It would require a LOT of material to make a building reach all the way to space.

What's the point of /r/meirl? | It's basically /r/funny, but with a focus on self-deprecating humour, like you said.

What's really happening inside our heads when we suddenly don't remember driving somewhere (space out), but we still made it just fine without crashing? | I think there's actually a name for it, but I can't remember it.

In the U.S., why are there only two major political parties, and why don't the other parties get equal time in the media?

Dis... |
How Stephen Hawking speaks through his computer | That's the gist of it, although Steven Hawking can no longer type since he lost the use of his hands.

We do not detect any such matter-antimatter borde... |

Read an article that said a large hadron collider disproves the existence of ghosts.

Can we run out of 7 digit phone numbers one day? If not why? If so what would we do to give new phone owners new numbers? | Same thing we've been doing for the last 70 years - add new area codes.

The shift away from 3D and vividly colored graphics to flatter more geometric designs. | I'm pretty sure there is precedent in psychology that I can find but I think it relates to us wanting to make these things as simple as possible so we don't have to think about it at all.

Why does the mass media present or exclude information as they see fit? | It is for the same reason that buzzfeed uses clickbait titles. Revenue.

Why when making a new product (food most of the times) advertised as limited edition companies sell it for very, very long time and it becomes available permanently? | They are implying scarcity, which makes people want to buy more of it or not put off purchasing it.

That being said, there are also cases where... |
Is "being chilled" a real thing or am I imagining it? | This could be a result of your body producing less internal heat. Your body produces heat as waste energy in a number of processes.

Why are world leaders tolerating Kim Jong-un? | [This is Seoul]. It's a fucking huge city, with 25 million people in the metro area.

Why do colossal creatures appear to move so slowly? | Ask yourself this: are they really moving slowly? Say a humanoid creature ten times the size of a normal human is capable of swinging its fist just as fast as a normal human can.

Since the two jobs are really quite different it just makes more se... |
How does the face wash or your skin, even know what time it is for you to apply and it to work? | The time of the day doesn't really matter. What matters is that you wash your face before you rest.

Therefore, it's best t... |
Is there a hard limit to the maximum possible weight for an aircraft? | Kind of. The cube square law makes building heavier and heavier more difficult.

what would happen if the moon broke apart and/ or exploded? | The moon's own gravity holds it together. An impact of sufficient mass and speed could destroy or badly disrupt the moon and launch huge pieces of planetary debris into orbit around the Earth. Some of those pieces would eventually strike Earth and we'll have a really bad time. Fun fact: the moon itself likely formed fr... |
