    Theoretical question about the Sun

    True, I suppose I should have said no reason in regards to producing energy. you can harness a profound amount of energy by building collectors around the star. in that respect there is no reason to pull anything physical from the star.

    Your favourite AI character

    "The Machine" From the Series "Person of Interest" I feel the series did a wonderful job fleshing out the humanity in a character that almost never speaks directly. Until the very last few episodes it always communicated in directly with the characters but it was my favorite character out of...

    Theoretical question about the Sun

    As others have stated, building a shell or swarm around the sun would be the best way to collect the energy. There is no reason to physically collect matter from the star. If you did remove matter you would not "drain" the star, in fact you would lengthen its lifespan because you would be...

    Writing: Input Wanted Some problem solving -- probe is traveling to Alpha centauri

    I agree with Ryan_m_b. There are plenty of logistical reasons that a probe would have a far easier time then humans. manned crafted would have to be many times more massive just to house all the air, food and water needed for the crew, not to mention radiation shielding If you are going with...

    Disintegrator residue?

    Janus said the half life was about 15 minutes so that gives you a time frame to work with. Could your character crawl 30 feet in 15 minutes? probably, so maybe make it a longer tunnel. and I would say being out of the tunnel when the first explosion happens would be a good idea because after...

    Disintegrator residue?

    The side effect of explosive e-comprresification leads to an interesting drama point in the story. The tunnel is only a meter wide by 10 meters long so it is going to take time to crawl through it. As stated however, as the effects of the ray dissipate, the original mass will begin to explode...

    Disintegrator residue?

    For practical, real life applications, this could be a night mare side effect of the device. For a story however, it is a pretty awesome side effect.

    Disintegrator residue?

    I think the implication is a severe radiation hazard.

    Disintegrator residue?

    Most of what makes up matter is pretty much space, consider an actual neutron star, it has a mass greater then our own sun, yet on average, they are only a few kilometers across. Collapsing down 300sq. meters of rock would still take up a microscopic amount of space.

    Disintegrator residue?

    Another idea is that the device could increase the matter's density, causing the molecules within the affected area to collapse together, perhaps even to neutron density. so zap a door and the door would seem to vanish, the matter the door was made of would still be there, it would just be a...

    Need a fact check on the end of the world

    Thank you, you are correct in that is what I was looking for, I need something that would cause extreme damage to the ozone layer. I am looking for a culprit for a mass extinction. I wanted to avoid asteroids because they seem the go to for all all end of the world plots.

    New Blade Runner

    Though doing a sequel like this does kind of ruin the mystery of his character being a Replicant or not.

    Physics Behind Time Loops In Movies?

    Thank you for the clarification.

    Physics Behind Time Loops In Movies?

    I believe the only known mechanism to alter Time, is gravity. so if you had a situation where time was so distorted that it bent back on itself, then you would also be in the presence of a gravity well so enormous that time looping would be the least of your worries.

    Need a fact check on the end of the world

    Ok good to know, so low in the believability department. I wanted something plausible, I didn't pick a random Super nova because I figured any star big enough to explode and yet be close enough to do us damage, we would know about it by now. I thought Betelgeuse might work because its close and...

    Questions about space travel

    Yep, I was. Bond's model uses an air breathing engine so it can greatly reduce the amount of O2 it has to carry into orbit.

    I wasn't aware anyone had build a successful prototype yet. I know Allen Bond has been working on it for decades but I thought he was still working out the bugs.

    Futuristic Space Travel

    Issac Aurthur does an Excellent series on Youtube, he is very detailed and distills the information into very easy to understand segments, its perfect fodder for sci fi writers. He recently did a multi part set on realistic near future methods of getting into space, I believe the set was called...

    Questions about space travel

    If you are working with current technology then you need a rocket with a large amount of fuel and multiple stages. Currently no one has figured out how to do a single stage craft that can leave the atmosphere. So you are talking a large undertaking by a significant crew of professionals and a...

    I am collecting facts for an story featuring the end of the world. In this Story Betelgeuse is the culprit. I know currently its poles are not lined up with Earth so I need to describe an event that would alter its position so that when it goes, Earth is in the line of fire. Would a black...

    How does the Ori black hole drive work

    Phind's Answer of Magic honestly wasn't far off, and the Ori, I think would appreciate it as they were a race so advanced that they wanted the inhabitants of their galaxy to worship them as Gods. Some of the only Ori tech explained in any degree was their genetic engineering of the Priors...

    A Structure or Material that can withstand a million years on Earth?

    Agreed on all accounts, but there is at least the possibility that a few might last that long thus given room for plot fuel in the OP's story.

    A Structure or Material that can withstand a million years on Earth?

    That is certainly one way to go, have something in orbit that eventually falls back to earth. The satellites in orbit will last practically forever barring any collisions, as their power supplies fail, their orbits will decay over a long period of time and eventually fall back to Earth. For the...

    I Question about Relatavistic mass

    I am trying to get my head abound something and I am hoping you guys can shed some light on this for me. When discussing objects moving an relativistic speeds, its often mentioned that as an object approaches the speed of light, it gains mass. My question is: is this mass real? If you...

    Writing: Input Wanted A completely alien sky

    Just make sure your plane is in relatively the same position in the galaxy. You can move it thousands of light years but you want it to be about the same distance from the central bulge and in between the arms of the Galaxy. This is important because much like solar systems, the Galaxy also...

    The future of technology in Sci Fi

    yeah there are ways to simulate the effect but what was shown in the scene was a thin foil like material that some how managed to trap 100% of the heat of the hot coffee and keep it perfectly contained for seemingly weeks or maybe months. Also it somehow managed not to expand from the steam...

    The future of technology in Sci Fi

    My favourite Tech would be perfect insulation. I forget what movie it was from but there is a scene where the character reaches into a cupboard and takes out a packet that is seemingly at room temperature, he opens it and pours steaming hot coffee into his cup. I remember not being very...

    The future of technology in Sci Fi

    I read about a very similar story in the 90s, An American Tourist and Japanese Tourist, I forgot which country they were visiting but they discovered that they both spoke Klingon and communicated that way without knowing each others' native tongue.

    Best way to sneak up on Earth?

    Well there are a couple of ways you could go here: If the aliens are crossing a gap of several lights years in a relatively short period of time then it means they are moving at a very large fraction of the speed of light. that kind of energy utilisation speaks of a civilisation far removed...

    Physics Problems on Flash Tv Series

    I have found almost no science on the Flash that resembles actual science. The very foundation of his ability relies on something called "The Speed Force" which is apparently sentient. Beyond that, even basic physics are inconsistent in the show. For example in one episode he can move so fast...

    B Survival on Mars?

    The big problem with setting up a colony on Mars is that it *would* take a staggering amount of resources to get it started, there is no real way to shoestring it. The biggest bottleneck is power. Things like building structures and 3D printers to fabricate tools and greenhouses all require...

    B Survival on Mars?

    I don't think we have to worry about anyone from Mars One dying on camera. It is extremely unlikely that this organisation will ever get anything off the ground. The plans they have proposed and the budget they outlined are not even close to realistic. You don't even need to get into the...

    Insights Planning to buy a first telescope? - Comments

    The really cheap telescopes are not very good at seeing dim objects because they have really small apertures and do not collect a lot of light. my first telescope cost around 100 quid and the moon was really the only thing I could easily see.

    Rogue One: A Star Wars Story

    While this story looks very promising, I hear it is the first in a series of side stories, the next one slotted for 2018 is a Han Solo & Chewy Origin story, for this I weep. I think with Rouge One they have a great idea, a story that has never been told that tucks neatly into the Star Wars...
