What I feel we should do when/if we develope Faster-Than-Light travel

If it was real, it should be used to transport people in need to hospitals, lots of people died during their way to a hospital.
What we should do is not leave it in control of one godlike psychic emperor.

Sufficient accuracy for me.

There are so many blatant scientific impossibilities and you chose to say that you'd need a huge telescope?

Yes clearly I did.
[QUOTE=commander204;28206671]Nice one.
Anyway, there is no reason why you can't go faster than the speed of light. Other than that you can't accelerate without hitting something. Remember Newton's laws. One of them is: An object will not loose it's monumentum without another force influencing it. Now what happens if you push a rock for several years? At some point it has to go as fast as the speed of light. If it will go faster? No Idea, because it's energy tends to be really high.[/QUOTE]
Don't you love it when people just pull bullshit out of their arse?

No, no, no, a thousand times no.

[QUOTE=Contag;28207428]Basically, (even though relativistic mass, and Newtonian mass are different, it's good enough to get the point across), as the energy of an object increases, it becomes more difficult (requires more energy) to increase its velocity.
To reach the speed of light, an object must have an infinite amount of energy, just the same as the relationship between energy input of a car traveling 100 metres per second, and 0.50c would not be linear.
But what about light? If something requires an infinite amount of energy to move at the speed of light, how can photons travel at that speed?
They can travel at the speed of light, because photons have no (rest) mass, which is why the speed of light is deemed as the absolute maximum speed a non-negative mass particle can travel.[/QUOTE]
There is no such thing as relativistic mass. Mass is a Lorentz invariant.

Ok guys, we need ideas for infinite energy![/QUOTE]

How is it that I managed to learn more about the Universe in less than 100 posts than I did in Quarter 3 of Intro to Physical Science?
[QUOTE=Ardosos;28196815]While chipping away at the ice today, I was thinking about Space. I was thinking about how everything that we see happened several thousand years ago, and light takes time to travel to our planet from other stars.

Are you sure you weren't [i]smoking[/i] ice?
I never grasped it.. Cookies if you read and relate.
Let's say I am right now on point A, and I wish to fly straight to point B..
Point B, however, is in another entire galaxy, and there is a person waiting for me to visit right there sitting on the spot!
I do not know how long it would take me to travel the length, but just for the sakes, let's say it would take me 9 years.
Point A -> 9 years -> point B, somewhere very far away.
In year 2011, I tell my friend sitting on point B that I will be coming right over, he says "okay, I will wait for your arrival", and off I go. He waits for 9 years, while I spend the time traveling, then we will finally meet.
Time rolled on same as ever, but according to science, this is not the case. Why, or how? [b]Are they even certain that no mind can share the same thought at the same time somewhere so far away it would take the speed of light to travel the length?[/b]

quote me again, i edited. also, the bolded question, if you wouldn't mind to briefly cover it, as the wikipedia article seems like a long and a bothersome read and after all i am not a scientist but merely interested about the matter
I'm confused as to your question. Sure two people can think the same thing, or relatively similar things, at the same time, but if two events are connected by a space-like interval, they're causally disconnected.
[editline]22nd February 2011[/editline]
i.e. since light is the maximum speed limit, information cannot be transferred faster than light, so events that occur close enough together in time and far enough apart in space cannot possibly be causally related to one another because light cannot have traveled between them in the time between the events and therefore nothing can have traveled between them.

If I were you, I'd be interested about the energy too.
[editline]22nd February 2011[/editline]
Also, no distance is so far away that it would "require" a certain speed to get there anyway. To get there in a certain time, of course, but not just to get there at all.

Not if you are planning to get to another universe without a worm hole or vigorous amounts of energy in one spot. Going past the speed of light would technically set you in another universe which physics support FTL speeds to prevent the universe you know and love from crumbling into oblivion.
[editline]23rd February 2011[/editline]
Although that is just a theory.
First off, we will not be able to travel faster than the speed of light. Our bodies just cannot handle that kind of stress.

Not if we are light. Matter to Energy conversion.
[editline]23rd February 2011[/editline]
Or creating a deadspace bubble of sorts, allowing time and matter to float past a object while the area enclosing the object is still, using something of a strong as shit magnetic field, kind of like how an atmosphere protects a planet from cosmic threats.
Is it possible to make a light that goes faster than light?
Assuming FTL travel is possible, and ANYTHING is possible, probably not. The only way I can think we would travel faster than light would be by bending space around us (warp drive), and setting it back. When we set it back, we would have not altered time, AH FUCK IT JUST READ THIS

Yes, everyone, we will send patients to hospitals at lightspeed. This will no doubt have no problems such as colliding with pretty much everything, the stress on the patients body, or the theoretical major passing of time during that speed.
It is perfect.

Just wondering, if we can make things travel at faster-than-light speed, then how would weapons develop? Faster than light nukes?
What about wormholes?
[QUOTE=Contag;28207848]He's right though, you can time travel forward, just go in circles at 0.99c, and barely any time will pass on your end, whereas time will pass normally from Earth's frame of reference.[/QUOTE]
Going in circles at 0.99c, Do you want to be a microscopic layer of diamond on your spacecraft's wall.
[QUOTE=Kingy_who;28228430]Going in circles at 0.99c, Do you want to be a microscopic layer of diamond on your spacecraft's wall.[/QUOTE]
It's all a thought experiment anyway, I think the 'going at 0.99c' is where it got massively unrealistic.
Of course, if you could go that fast, you could probably upload yourself to a computer and put yourself on standby.

I don't think any computer could handle to forces involved involved unless the circles covered billions of light years.

You could probably fly in a circle the size of Earth's orbit around the Sun (~ 1/9000 ly) and the centrifugal force would hardly be noticable.
