If the upper limit of speed is the speed of light, you would not be able to accelerate once you attain this speed, hence there are no G forces at the speed of light.


1. you, being a massive object, cannot attain the speed of light in any reference frame
2. "g forces" are fictitious forces arising due to the acceleration of the observer's ref frame.
as one approaches the speed of light, things aren't linear anymore due to the lorentz factor so it is possible to feel great forces despite tiny changes in velocity.

In fact, assuming infinite energy, it's completely possible plan out a route that can accelerate yourself to the speed of light without exceeding the minimum acceleration required to reach escape velocity from the sealevel.


In fact, assuming the impossible, it's completely possible to do the impossible. ya sure.

So... vision refreshes at 60FPS? Nice...

no more like infinite fps with motion blur (or temporal low-passing) that depends on the amount of light hitting your eyes. like what you see at time=5seconds is a mixture of what you see at time=4.7 4.8, 4.9, 4.95

1. I addressed that later -.-
2. G force being the nominal "unit" of force you see in those scientific documentaries. His words, not mine, I'm just setting up a reference point from which I can make a comparison between his claims and mine.

fine fine, 10^6 tons of force, can't I make mistakes anymore? Jeez

force is a vector
wat direction???


HAHAHAHA i lol'd @ your post...thx u made my day XDDDD

Still I agree faster travel would be nice...JUST NOT @ LIGHT SPEED D=

Yeah, sure, we can travel at the speed of light if we want some vehicle barreling into everything, material and living alike, at the speed of lightning

Seriously, we already seen how bad somebody getting hit by a falling plane would get, now multiply it by 5 million times and Bam, you've got a Berserk machine that could be mistaken by everybody to be a Super AI robot on the loose or something

Also, the G's would be massive, a normal human being can stand 4 G before blacking out, 6-7 G would turn a normal human being into something not so pleasant, Lightning flashes at about *100(Wild-ass guess) of our blinking time, so sure, if you want a hundred G's or so, go on, but i am staying here

Again, moving really really fast might not be the answer, rather more cunning ways of traveling through the stars.

like what? moving really really slow?

We'll need insane technology and heavy amounts of power to ensure a portal doesn't collapse on you right when you are travelling through them, so no

Perhaps some of these people really should not be participating in this conversation.

My 2 cents:
Light speed is perfectly possible, provided humans are not travelling in it, after all, travelling at light speed and suddenly being hit my a star's gravity would probably make your brain go splat on the side of the wall.

Technically, if we travel at a speed close to the speed of light, the time that we travel through will be close to zero.
So we can travel the 25k l.y. in about 0 seconds, but when we return to Earth, we won't find the scientists engaged in that project anymore, maybe we won't find even the Earth.

I agree with you but not every corner of space is full with meteors and asteroids. If we jump from place to place it doesnt need to happen

Time doesn't slow down if you go faster, I assure you. Time simply cannot be slowed down.


It is. We need to travel faster than time itself

@FlooD:
Actually, I think I finally got what you were trying to say in #1. When we perceive ourselves to be stationary, we are only so relative to the ground. As not only is the earth itself rotating around its own axis while revolving around the sun, but also the entire solar system and even the milky way galaxy is in constant motion relative to some other point, we can't ever claim that a body of mass is ever at rest because it will always be in motion with respect to some other body of mass.

Since all bodies of mass are equally favorable as the reference point of motion, we can't claim that there exists an absolute frame of reference. For this very reason, the concept of an object moving at a "constant" velocity is inherently contradictory.

On the other hand, maxwell's derivation of the speed of light is completely independent of any positional variables, which seems to fit the contradiction described above.

To better illustrate, let's say that we have two trains going in the same direction with the same relative speed on earth. To an observer standing on the ground, these trains appears to be moving; but to a person sitting inside the first train, the second train will appear to be stationary. This is pretty intuitive. So if the first train is moving at 90% of the speed of the second, the first train will observe the second as moving forward with a speed corresponding to 10% of that of the second train. Again, this is common sense, as the faster race car will undoubted surpass the slower one.

However, because light's speed is constant regardless of position, it doesn't change when we change the reference point.

In other words, if you stand still, you will find that relative to you, a ray of light will travel past at a rate of about 300000000 m/s, but if you were moving at 99.999% of the speed of light, that same ray of light will still travel past at 300000000 m/s. In fact, regardless of the reference frame, the speed at which light travels will always be the same. This becomes a bit problematic as we approach the speed of light ourselves.

Now we can blindly place our trust in a few crazed and ambitious men from the last century and take it at their words that there exists a "total speed" for all bodies of masses in this universe that includes x, y, z, and time as its components. Now this is a strange concept as this "total speed" is a constant speed in which the speed of the flow of time is also a part of its components in addition to what we normally consider the speed of an object in our 3D world. Anyways, this "total speed" is presumably the speed of light, and as it is the sum of its components, whenever we speed up in the x-y-z speed, since the "total speed" must remain constant, we must compensate by subtracting from the speed of time for that object. So for the sake of rhetorics, if we have an object approaching the speed of light, the flow of time approaches a screeching halt.

i couldnt agree more, thats impossible just like reversing time (time machine) or going forward in time

also, about aliens i completely belive in them.
no, not inteligent beings but rather alien critters intel equil to that of a dog or cat of something
but, however if aliens are smarter then an average animal
like the other guy said (sorry dont remember you name)
"they'd still be learning to start fires"
but who knows, maybe beyond all of those uninteligent aliens theirs an overlord or rather an intellegence equil to human or maybe even more...

also, thinking about unlimited space, its creepy dont you think going out so far... far... far... thinking "does this void ever end"

thing about space, its such a lonely, creepy, devilish place

@joel:
It is possible to REVERSE time, there would just be no way to get it back. Also, if you had to go through time the object will have the same universal position as it did when it was sent backwards, therefore discarding it in space during the past if the Earth ( or other mass it was on... ) was not in the EXACT same position as it was when the object was sent backwards in time.

I'M CONFUSING MYSELF READING THIS?!?

i have no idea what you just said... but think about it, how IS time travelling possible, time cannot be changed.
past does not change, only the future does
