Since light takes time to travel from distant stars to earth, does this mean our night sky is consistently being "updated" with new stars? | Yes, although it's not like they just "turn on" one night. Stars take many thousands of years to be born. > If so, would this mean that eventually the night sky would become so densely packed with stars that differentiating them from one another with the naked eye would be impossible?

Also, why, during eye fatigue, is it advised to look at distant object instead of simply shutting the eyes? | Don't quote me on this, but I wanna say your eyes try to pick up on images or shapes in the dark rather than completely relaxing.

Why you cannot make a super computer by adding lots of CPUs and ram together? | It is possible but it doesn't help for many problems. The classic example is that nine women can't make a baby in a month. Some things have to be done in a certain order.

How this company's stock went from $0.68 to $15.46 in 2 days | Bankruptcy isn't the process of dissolving the company, necessarily. Chapter 11 of the bankruptcy code is a reorganization.

Your creditors agre... |

Why do companies provide open source software? What is the benefit of providing free software when you could be making money? | Open Source Software is known for providing security advantages, because many more developers are working on and looking at the code at the same time, versus a proprietary software where the source code is closed source.

How does a spider form such a near perfectly angled and structured web? | I did a little bit of research into it and it seems they are not as "perfect" as it seems. For a traditional web that most will imagine it starts with a single "bridge thread" where the spider throws a line of silk hoping to get it to connect. The spider would then work on creating a frame and finish off with a spiral ... |
Basic Question: What IS the "Superposition" in Physics? | The basic idea of superposition is that something can hold multiple states simultaneously until it is observed/measured, in which case a single state is adopted .

How do you become a voice actor/ presentation reader? | First, we want to differentiate between voice acting and voiceover .

How can the batteries on Tesla vehicles manage to get fully charged within 15 mins; while latest smartphone batteries can take upwards of 1-2hrs minimum. | In the Tesla, the batteries are cooled much like the engine in a normal car. This is because discharging and charging batteries is not 100% efficient, you will always lose some energy to heat - the faster you're charging, the more you lose.

Why are BBC produced nature documentaries like Planet Earth and Frozen Planet given a new narator for US audiences? Why not keep David Attenborough in the US version? | Like every TV network decision, it's based on what they think will appeal to the widest audience and thus make them the most money. Maybe they think that having a British narrator will make the show be perceived as a "stuffy" documentary and therefore too boring. Maybe they just think that people will be more comfortab... |
How does "home field advantage" work? | While these other factors certainly play a role, the vast majority of homefield advantage arises because officials tend to be subconsciously biased towards home teams.

why are spinning objects more stable and balanced? | Since there the velocity of any point is pointing tangential to its rotation, when you apply any force perpendicular to the plane of rotation of the disk the two momenta add up and cause it to tilt 90º away from where the force acted. This way, the object precesses instead of falling straight down. It's all perfectly e... |
How does DNA actually contain the blueprint for an entire organism? | DNA is a chain of four bases in any order for millions upon millions of bases. Eg: ATTTCGGAGC TAGCG.

can anyone give an insight on what is happening inside a computer, from the layer of logic gates up to the OS? Thanks | If you literaly want someone to walk you down from the operation system down to the electronics you need a lot of time. Anyway, i will try to give a very vague explenation: all software today, including OS, are written in so called higher programming languages such as C, C++, Java, Python, whatever. This code is then a... |
Why does fat usually gather around the midsection/waist (lovehandles) instead elsewhere on the body? | Because your core doesn't have the same range of motion and precision requirements as your arms and legs.

Why non-veterans and military get off from work ( & school?) on Veteran's Day. | It's a federal holiday. Schools are off on most federal holidays.

How can computers give random numbers? Please explain it from the transistor level too | There are various levels of "random".

Why is a green screen "green" as opposed to other colors? | Technically speaking, the colors can be gray, white, black, or purple, but green and blue are used most often because they "stand out" the best.

how to predict trajectory angle and power to shoot a target at known distance (for games like Bowmasters and pocket tanks). | The range formula allows you to calculate the horizontal distance from the initial velocity of a projectile at a certain angle : R = Vi^2 * sin / gravityGeneral rule of thumb, try to estimate a velocity, angle and timestep and do some classical mechanics. But a better rule of thumb is that each game may implement proje... |
Why 30 fps and 60 fps? | It has to do with the frequency of mains electricity. In Europe we generally have 50 hertz, which is why PAL is 25fps. The US has 60 hertz therefor NTSC is 30 FPS.
