Warp Drive Might Actually Be Possible

[ShadowKatt]

How do you hit the brakes in space..?

Braking in a zero gravity/zero friction environment means that you simply apply thrust opposite the direction you're going. It either means putting engines in the front of your ship to slow you down or rotating the ship to fire the engines against your current velocity.

As for the warp thing...I'm less worried about how to stop and more about how you see where you're going. If you warp the fabric of space then you also warp everything IN that fabric of space like light and other forms of radiation. Meaning you could not see(clearly) what you were flying into.

Hmmm.....
Isn't that similar to how FTL travel works in Mass Effect?

No, in mass effect they flow a current through element zero via dark energy, with a positive current, mass is increased, with a negative current, mass is decreased. So they lower the ships mass to nothing and this allows ftl speeds, so to do it the mass effect way we'd need a element that bioware made up and a hypothetical form of energy that may exist.

Wouldn't being massless mean that they travel at the speed of light, not faster than it?

Just wondering - if a functional FTL drive is invented, what happens to the funny time-related consequences? Would you arrive at your destination before you left?

Well if its possible then the laws of physics would have to be re-written.

Nothing in Quantum Theory states that warp drive can't exist. I'm not aware of anything in physics that would need to be rewritten.

You aren't moving faster than light, you are bending space. The ship itself isn't actually moving. Similar to pulling on a table cloth to move a salt shaker on it, the shaker is motionless in relation to its surroundings. It is the distance itself that is being shortened.

According to the Codex it reduces the mass completely, creating greater acceleration, which somehow raises the speed of light within the mass effect field, which also removes Time Dilation (which is effectively travelling forwards in time by moving so fast).

Indeed, it's not as much "FTL" as it is "Taking a short cut while the light goes the long way around" thing. Similar to you making 10 steps uphill while your friend in the car has to take the road up the incline and make a wide turn, you're still slower than them, but you'll be from point A to point B quicker than they are.

However, since "light" is our main means of transmitting and receieving information, that could lead to some funky stuff. Or at least it's going to look funky until we have this spacebending thing observed more extensively. And they thought bloodbending was the real deal, pfsh.

I have a feeling the codex writers never took a science class.

That was fun to read but mostly made no sense. Thanks for the insight though.

Basically the speed of light (c) IS presuming a vacuum devoid of mass [non-photon particles].

If the space it is traveling in is not completely particle free the speed of light becomes slower (mostly due to it bouncing off of particles as it travels, changing the straight line into a zig zag one).

Well, to be entirely honest I think Einstein will be proven wrong at some point, just like other great minds before him. To me the idea that light speed is as fast as you can go, and that to travel faster would effectively mean you'd be travelling through time has always struck me as being pretty wonky, even if it can be justified mathematically for the moment.

That said, this is an interesting development, time will tell what's going to happen with it.

I honestly expect we're likely to re-write what we know about physics more than a few times, maybe even before my lifetime is done.

The world economy as it is is sadly built around exploiting that starving side, and that includes science as well. Such sacrifice is made for theories. One can only hope that some day, these theories can somehow help those of us starving and killing each other to stop. To me, that's as important, nay, more important, than getting to other stars.

Let's try to make this world as good a place as it can be, -before- we try to go ruin other places. That at least makes sense.

The world economy really just cares little about the poorest nations of the world. They have minimal infrastructure (for transporting products and electricity), little education (for a workforce that can do stuff other than manual labour) and no stability or safety (Kinda hard to set up any industries when they might be raided, looted and burned down with all the employees killed). The only reason to ever set up industries in these nations is because the wages are low.

The vast majority of science is done for the purpose of making this place as good as possible. The 20th century has been the least violent century so far, in terms of % of male deaths that are caused by warfare, and the 21st century looks like it will top that record. More people now die from obesity instead of starvation.

We produce enough food for 12 billion people. Why are some people starving? Is it all the people in the first world being greedy gits and eating it all? Not really. You know the infrastructure problems I mentioned earlier that exist in the poorest nations. They make it very difficult to transport and sell excess food to them. Additionally, mass-dumping food on these nations tends to destroy the economy as it puts the farmers that live there out of business.

I love reading articles like this. Always nice to get a good dose of optimism.

Even the comments so far are better than the typical for these types of threads. There are fewer posts by cynical folk who like to pretend they know what they're talking about with regards to science/mechanics.

 

[UnderCoverGuest]

Science is cool.

 

[iblis666]

ok so we now need to find a way to harness dark energy or zero point energy or reduce the energy cost to a manageable amount of antimatter

 

[FieryTrainwreck]

They should probably test this stuff in space. Preferably the next solar system over.

Although it is fun to think about them perturbing space on the surface of this planet. What if it's a shockwave that shifts every particle on the planet like 1cm? Would everything be instantly disintegrated?

How do you hit the brakes in space..?

The problem with current theoretical brakes that would be easily developed is that the brakes would kind of destroy your destination. They're still working on that part.

Brakes aren't needed at all, since the object in the warp bubble is not actually moving. What the field is doing moving space around the object. In Star Trek this is why they aren't affected by time dilation. If this works the same way, then it too should avoid the time dilation effect.

in addition, its prety safe! power goes off > movement of the bubble stops. but your still IN the bubble. so even if you would stick in say, a ROCK your air bubble would still be there so you would not get crushed! *dont ask me where the rock part would be, im guessing where you can from*

clearly the pursuit of scientific knowledge is a waste of time and we should continue to cut governmental funding to such endeavors *glares angrily at the NIH & NASA*

All I could think of while i read this was Star Trek First Contact
