negative mass doesn't exist

>>5889098
So what would I use instead of negative mass?

>>5889089
All science-fiction is hand waving. That's what makes it fiction. Your job is to explore the consequences of the technology existing, not to explain how it works.

>>5889098
Anti-particles are like negative mass if you think about them mathematically. Particle+Antiparticle=annihilation=no more particles=no more mass.

>>5889105
I know, but I like being able to say that technology within my fiction is based on real life and is plausible.

>Is FTL plausible

No. Didn't even have to read it.

Bump

>>5889106
No, they fucking aren't. They are more like particles moving backward through time.

Seriously, read 'A Brief History of Time' or some Feynman or Krauss or something, son.

Shit son.

>>5889141
>They are more like particles moving backward through time.
listen to yourself man.

>someone's never seen a Feynman diagram

>>5889089
it might be more "realistic" if the ship opens the whole wormhole end to end

it doesn't really make sense to go into a wormhole with no opening at the end.

>>5889089
sounds like the ship Event Horizon in that one movie. I think it was called "The bus that couldn't slow down."

>>5889180
Thanks, fixed it.

>>5889182
Nope, movie and the ship had the same name.

>>5889105
this
also, go deep into what this kind of technology allows or its limitations.
can wormholes be generated anywhere? is it bad to open them inside an atmosphere? has that happened before with disastrous consequences?

if they can be opened anywhere, even at micro scales, could all electronics use these to allow for instant communication? has to revolutionized the internet? how about manufacturing? or shipping of products using home wormholes?

did one of the characters design this system? does he work with them like a mechanic? was he debilitated by them and now has a missing arm or something and distrusts them intensely?

explore these questions

- The wormholes are used for interstellar travel, not being generated anywhere. Using it inside of an atmosphere has...bad consequences. During one of the wars the Earth and colonies fought against an alien threat (in the story, we've fought three wars with them), a Human ship made a "jump" into a wormhole inside of an enemy planet's atmosphere and basically burned the planet whole.

- No, the "FTL" system has been around since 2077. The main storyline takes place in 2219, so the main character hasn't helped develop it. But the Internet has been revolutionized since then. Cross-planetary communications is huge and the Internet is much more free than it is now; manufacturing/shipping is bigger with the colonies than on Earth itself.

>>5889236
In the early years, "FTL" was still being expanded on. Short jumps were common, but as scientists worked and expanded on it, larger jumps became more and more common. Now, a ship could jump from Earth to the Kepler-10 system (500+ ly away) in about three days.

>>5889236
dude you can't use shit in new stories that is so passe it is used in video games. play mass effect and halo again, watch the new star trek movie, and then don't do anything they do.
space travel in the dune series was actually unique and interesting. come up with something unique, doesn't need to be practical in the least

>>5889098
how can anyone on here say negative matter doesn't exist? We don't fucking know, you twat

OP is referring to the alcubierre drive I think, same "princible" behind space travel of the USG ishimura on dead space

If FTL travel was *possible*, aliens would have colonized our planet thousands of times over.

>So, rather than being straight FTL, they're more folding space to get from Point A to Point B
I'm not an expert, but couldn't you just call this 4th dimensional travel?

>>5889106
>Anti-particles are like negative mass if you think about them mathematically.
No, they are not. You have no idea what you are talking about.

>>5889264
Maybe its exceedingly rare for a civilisation to develop FTL travel.

So exceedingly rare in fact that no civilisation has been able to survive long enough to produce it.

jesus, this board is autism

>No, they fucking aren't.
You are righ..
>They are more like particles moving backward through time.
..wha..
>Seriously, read 'A Brief History of Time'
..

Christ, the popsci tripfags have invaded again.

oh my sugar i have never been more excited about an upcoming experiment

>>5889653
In particle physics in some situations a particle traveling forwards in time is equivalent , to some extant, to an antiparticle traveling backwards in time.

>>5889264 or maybe they dont fucking care about us.

>>5889653
He's right though.
You know about T-symmetry, right? There's a reason the arrows on anti-particles are drawn facing backwards. If you flip time on the diagram, you get an equally valid diagram. Likewise for other symmetries. It's like you've never studied QFT.
