"Tear Apart Space." In other words, ripping a hole in the very fabric of space and time creating a cascading effect that will destroy the entire universe! Way to go f***ktard scientists.

[quote]but an engine generating power for 50 years accelerating at 16.43 km/s per day traveling in a straight line, with nothing affecting the vessel will not require more power at greater speed as there is no force attempting to slow the ship down.[/quote]

The problem is that you`re applying Newtonian physics to a situation where it doesn`t apply. Newtonian physics is an *approximation*. It`s still used because it`s an extremely accurate approximation in any circumstances that anyone encounters in daily life, but it becomes less accurate as speed increases. It`s irrelevant at a significant fraction of c.

What would happen is that the acceleration of a vessel under a constant force would decrease as its speed increased and the faster it got the more its acceleration would decrease. To reach c would require infinite force, which is clearly impossible.

That is true for slow-moving objects. "Slow" in this context being anything up to a few hundred million mph.

It is not true for objects approaching c. That is constant in all reference frames. Bizarre though it sounds, it really does seem to be true. From your reference frame, they would be approaching you at c. From their reference frame, you would be approaching them at c. From any other reference frame, you`d both be travelling at c. c is always the limit, that`s why it`s a constant. Your movement through spacetime will change as required to accomodate that constancy (time dilation, length contraction).

It`s weird, but it has been repeatedly confirmed by experiment.

Lolz at the people arguing over relativity on a subject that requires quantum mechanics. Catchup with the times.

Don`t watch television shows if you want to understand something. Television only gives the illusion of knowledge.

Oh great! First science says there`s no such thing as Ghosts and now Science says there are ghosts but they`re teeny tiny. You can`t see them but they`re there.

... his theories are forever being tested and questioned. Why? Because they are scientific theories and while his theory of relativity works in most Earthly situations, it does not seem to work by all the laws of the universe... like say at an Event Horizon or at what we call a Singularity. Furthermore, it is completely genious to be testing this laser idea to "rip" space fabric because of how little we know of Dark Energy and Matter (energy that is theorized to be pushing everything apart) (matter theorized to be holding our entire universe together)... and so on.

OK there Batmanners, that`s enough out of you. If you were so studious as you say then you would know that Einsteins theory is forever being challenged and there is concurrent evidence that his theory is flawed. For instance, there is evidence of Light slowing down in the universe. Plus in order for the big bang to have occured and is still ocurring today, Nothing (which is still something) is travelling faster than the speed of light. Being that the big bang did actually happen... it has been proven and we can actually see the universe when it was 360K years old (roughly 13.65 billion years in the past).

More over, we have proven the existence of dark matter, dark energy, and anit-matter and have shown them all to be the foundation by which our existence hinges... Einstein, while still a genious... (continued)

"Batmanners, no offence meant, but you need to read a book on this subject.È

I`ve read dozens, and watched all the Carl Sagan/Stephen Hawking TV shows I could, and many many others. What I haven`t done is enroll in a physics program in University. Because then my job would be to try and make an equation to prove Einstein wrong. And that is one hell of a job to do. In theory, his equation may make complete sense, but practically, I donèt know if it applies.

I`ve done "some" research on this subject when I was young, and came to a few conclusions, such as everybody jumping onto Einstein`s boat that it is impossible because of the theory of general and special relativity; to say FTL is possible is to try and prove Einstein wrong.

I`m not trying to prove Einstein wrong, but an engine generating power for 50 years accelerating at 16.43 km/s per day traveling in a straight line, with nothing affecting the vessel will not require more power at greater speed as there is no force attempting to slow the ship down. Well after 50 years they are at 99% of Lightspeed, the engine still has enough power to keep going for 5 years, all of a sudden the ship will stop accelerating? If so, at what point? I have heard that the closer you get to lightspeed the more you need to accelerate because time is distorted, but that should not matter, to an observer, you are just going really fast (maybe faster than light`s ability to reflect off y

"unless we have some super secret method of turning mass DIRECTLY into energy in a controllable way, which we don`t."

E=MC(squared) has been around for decades. It is essentially the equation for mass being turned to energy and the opposite. If it were not for this equation we would not have nuclear reactors, hence turning mass into energy in a "controllable" way.

I truly hate reading the gross ignorance in these comments. I am not a formally trained astrophysicist or anything of the like. Everything I have learned about modern science I have read in books or online. Why the drat are all you people commenting on poo you obviously know ZERO... drating NOTHING about? You pathetic monkeys...

I mean, FTL travel may not be possible, for us, but theoretically, I would like to know that I could if I was given the means.

Do you want to go faster than the speed of light? Go towards the light itself. Light is coming at you at the speed of light in our atmosphere, if you go against the light, you are technically going faster than light.

Compare it to a car going 100km/h and another car going the same speed in the opposite direction, what speed will they cross at? To either driver, the other car will be going 200km/h.

Now your walking speed may not even be a nudge in the grand scheme of FTL travel, but still, to you, the light is going faster than light.

If you`re in space in an incredibly fast vessel, what does it matter how fast the light is going past you (as you near light speed) if there is also light coming at you at nearly 2x the speed of light, and light hitting your sides at regular speed.

And in my honest opinion, look at everything big and significant in space, Pulsars, Quasars, Black Holes, White Dwarf Stars, they all have something in common: Extreme density with extreme gravity, exponentially grater than Earth`s by thousands, if not millions.

I`m no expert, but this test is absolutely useless. The best thing to do would be to take cues from objects with extreme gravity and learn from them (as extreme density control could be the key to .0001% below lightspeed travel)...not emit LASERs in space and cause destruction "a la Death Star".

And something I`ve been saying since childhood: What force is preventing you from reaching a speed greater than lightspeed in space? Does light`s own mass hit you with such force that you can`t go faster? Do you turn into energy? Does the space police stop you?

Pretend you have an engine that accelerates 10,000km/s per second. What will make the acceleration go down to 0?

Issue #1: I`m curious, what will be at the focal point that will redirect the beams of light into one? If the result of these beams is something beyond our sun, then no prism could withstand it, and the beams would go through each other, as light tends to do.

Issue #2: The expected result is to tear through the vaccuum. Where will the laser stop? Is it safe to aim something hotter than the sun anywhere we want? What if the laser has mass, goes into an extremely large orbit and comes back to kill humans in 5,000 years? (lol, as if we`ll make it another 5000 years)

Issue #3: If it will tear through the vaccuum, is Earth the best place to build it?

Great. The world is going to elect some grizzly, nasty old guy as their first galactic empire. Next thing we know, Pluto`s been destroyed by the lazer to prove once and for all it isn`t a planet.

If you need me, I`ll be moving to planet "Canada."

TKD:
It says power, not energy. So the laser fires for a very short time, during which the rate it expends energy at (also known as power) is the same as the rate that the sun delivers energy to the Earth. The difference is the sun does this continuously, and the laser would only support this for a very small fraction of a second.

"Capable of producing a beam of light so intense that it would be equivalent to the power received by the Earth from the sun"

Am i really the only person that caught this? This is currently impossible, unless we have some super secret method of turning mass DIRECTLY into energy in a controllable way, which we don`t. The amount of energy bestowed upon the earth each day is such a huge amount that we can`t even hope to generate a tenth of the amount with current tech. Point is, a laser with that much energy requires that much energy, which we do not have. Thus, this article is a lie. I`m not saying the story isn`t true, but this articles facts are as credible as a toddlers.

"Vacuum is nothing more than an absense of pressure (or atmospheric molecules). How can one "tear apart" something that`s literally NOT THERE?"

Wow, so Dark Matter, Dark Energy, Anti-matter, and a hundred other things that, ten years ago, was science fiction in hokey TV shows; all this is chalked up to simple nonsense by the armchair astro-physicist? You represent a (sadly) majority of people who not only will be left behind by science, but do not deserve to come along... being so dismissive about this scientific process by which you benefit is why humanity may not survive the brief existance it has already lived.

I mean, don`t you think for the sake of science we should fire it for a little longer? What if it`s JUST about to rip a hole in space to the parallel world where Pokemon is real, but it needs another 3 trillionths of a second?

I just did some interesting math. They talk about the huge amounts of energy that must be stored to use in the laser. The laser will fire a 200 petawatt beam for less that one trillionth of a second. That works out to about 0.055 kilowatt hours, or about half a penny worth of electricity from a North American power company.
