to me, even we are native on Earth doesn't mean we completely 'own' thing (in term of unmovable like 'land') if new comer don't interfere with native very own way of life, to me, they don't need permission... be it human&alien or native american&European colonists (but we all know how European...

If alien were to establish a colony on earth, do they need human permission? ----------------------------------------- let's say they show up on sky where not belong to any country and create artificial island on international water to set up their own colony. even assume that they were...

If I'm really gain weight more than 100 gram from 100 gram food where that extra mass came form?

simple question, please tell me if my understanding is correctly or not ------------------- our body mass can't come form nothing, it have to come from 'food' we eat. so, If I'm eat 100 gram of food, no matter how high calorie that food is, I never gain weight more than 100 gram. correct...

sorry if like I'm not respond, I just try to understand what you guys are talking. so... in theory, not just star but anything can become black hole as long as it's escape velocity greater than light. right? I also post same question in my country as well, some says, if planet mass keep...

first, what I know about black hole is; It has so much mass that collapse into itself create gravity field so strong that even light can't escape. and normally, black hole born only in giant star explosion. but what 'IF' normal rocky planet happen to collect mass (by asteroid, gas or...

sorry to push this up again, but I don't want to post a new topic. if photon can act like wave by passing both slit at same time to create interference pattern. is it only happen in small scale? if it a wave-like particle, it should create interference pattern at any scale regardless to size...

okay... sorry but another question. If we can see light source through both slit. when I slowly move fringe A to B C D... E which direction light source will move to reappear and disappear? left? right? or popup from shadow between two slit?

than what we'll see? or just like #1 say? see light source through both slit?

from picture, If we put camera directly at screen and look back at slit. move camera around fringe A, B, C ... what we going to see? in bright fringe A, we should see light source through one of two slit, when in dark fringe, we should shadow between slit, and when in bright fringe B...

Hello there, it's quite a longtime since last time I pose my question here. ---------------------- '90% of money in the world don't really exist' I can't remember when or where I heard this form, not really matter. but... is it true? Imagine that Every single person in the world...

Hello, Chitose here Just as the topic said, I'm I right? to believe that our body never gain weight more than weight of food we eat (and drink). 'cause mass won't come from nothing. we eat 100g of food, when it came out is less than that, part of it become our body mass (weight, height...

yeah, but how they mix in match head in the first place?

this is relate to my work. If white phosphorus is ignite upon contact with air, How old Friction match use them as part of material without ignite it? http://en.wikipedia.org/wiki/Match#The_replacement_of_white_phosphorus and how they extract white phosphorus anyway? this...

I see, even hunger feeling is various form person to person. still no specific way to measure it in reasonable way. Calorie is like Gasoline, the harder we work, the more we want... nutrients is like motor oil, need to maintain moving parts... without any of those two... I'm doom.
