Will man ever achieve light speed in outer space?

Question

Remember that light is not solid matter; it's energy. This is why it travels at 186,000 miles per SECOND. Besides that, it has no weight. Solid matter has mass and weight. Please give your research along with your answer.

Answer 1

No.
I'm not sure how well-versed you are in relativity and special relativity. But.....the gist of it is that if take an object and start accelerating it faster, nothing noticeable happens for awhile. But when it starts getting significantly fast compared to the speed of light, let's say 30% of the speed of light, interesting phenomena begin to happen. The speed of light MUST remain the same, so time begins to dilate, or slow down, for the object, and its linear distance begins to shrink. This must happen in order for distance = rate x time to still hold in effect with speed of light for the rate. Distances and times actually have to change in order to make that constant stay the same. The speed of light in a vacuum is the one and only true constant that is always constant.
Another thing that occurs is that objects gain mass as they get nearer to the speed of light. So.....what happens is that as you accelerate it faster, it gets heavier, and requires even more force to accelerate faster, and then it gets heavier, requiring even more force........and you begin to see the problem. As the object, even a very tiny one, approaches the speed of light it begins to take enormous amounts of force and energy to speed it up just a little more. So much that we can't collect all that energy and direct it in one place, it's much more energy than is available even in our solar system.
So......no......people will never conquer that problem. We can't figure out how to collect enough energy to fuel our own economies through the next 50 years, and that is a much, much smaller energy problem actually.

Answer 2

Nope can't/won't be done...period.

m = m0/sqrt(1 - (v/c)^2) is the major reason why.

m is the inertial mass of man traveling at v = c the speed of light. m0 is man's rest mass as he takes a snooze in a hammock on Earth.

Check out the equation to see what happens at v = c. We have m = m0/sqrt(1 - 1) don't we? That's m = m0/sqrt(0) = m0/0 -------> infinity. Anything divided by zero is an indeterminate, which is sometimes called infinity.

Thus, according to Al Einstein's own equation, your rest mass m0 acts like a mass of infinite size when you hop along at light speed. That's clearly impossible; there's no way around it.

If you or your buddies have mass, they are just not going to get to the speed of light. This results because f = ma so that a = f/m; where a is your acceleration towards that speed of light. But look what happens when v = c...m --> infinity; so that a = f/infinity = 0 and you cannot accelerate any faster because your mass is way too big...infinity if you will.

In fact, one can show, using m = m0/sqrt(1 - (v/c)^2), that way before v = c, m gets so big that all the forces in the universe could not accelerate your inertial mass one more m/sec^2. That is, there is not enough energy is the entire universe to get your velocity up to exactly c; you will fall way short of the speed of light.

By the way L(v) = 1/sqrt(1 - (v/c)^2) is called the Lorentz Transform. Look it up on the web, its fascinating reading.

Answer 3

well it took me some time to get behind the concept of relativity about spacetime and so on and on.
it did not take quite as long to recognize that Einsteins theories break down under specific circumstances.

relativity is one thing quantumn physics another.

As long as there is no satisfying unified theory i won't go that far to tell everybody its impossible.
It looks like it is, but 70 years ago we thought time is abolute and some dozen decades before the earth was flat.

>^..^<

Did anyone put an eye on Quantumnelectrodynamics ?
it strongly suggests that there are a few things more going on. Advanced and retarted subatomic entities. The nature of light and its odd behaviour.

science findings often came when someone threw away traditional ideas to set feet on new grounds.
The history books are full of such stories.
Relativity is such a traditional thing in these days, that science seems really lurking for something new

I'm sure someday someone finds a way to sneak around relativity, like producing an infinite ammount of energy, but for a fraction of a second only to push matter in a state where its no more present in conventional sense, but having a hook to move it around.

who knows ?

aaah and putting my research along with my answer ... well
If i would be soo sure about such a method you would see me on the list of nobel-price winners

I would give QED a try .. you really get some insight about the current dilemma with light.

Answer 4

I think it would be pretty useless, as there are other means to travel much faster and I think we'll see their development in the following decades. One of those incredible ways to travel is known as the "wrap drive", which you probably heard of through Star Trek. It consists in bending space time so much that the points a and b end up being at the same place for a few moments, allowing you to travel well, without moving. At the moment it would take 6 months to go to mars, and that's just one way! Last year, NASA said it would be testing an engine capable of taking to mars in a few hours, within 5 years.

Answer 5

NO.
well this keyboard does not have enough symbols to represent the equations but i'll try-
It's all based upon Theory of relativity.
moving mass m=m0*gamma
where m0 is rest mass and gamma=1/underroot 1-v^2/c^2
where v is the speed of that substance and c is the speed of light.
Thus,
m0=m underoot 1-v^2/c^2
by this equation
if v=c then m0=0
that means if that substance gets the speed equal to the speed of light then its rest mass should be zero(which is not possible).

So on the basis of Theory of relativity by Sir Einstein, we can formulate that man can not achieve the speed of light.

Answer 6

Not according to Einstein's Theory. Light has zero rest mass. As an object increases in speed the mass increases, which will require more energy to accelerate the object to a higher speed. Once you have accelerate the object to a specific speed, then it requires zero energy to keep it at that speed. An object that does not have zero rest mass, will have infinite mass at speed of light, thus, it would take infinite energy to accelerate it to light speed. See link for the equation that relates Mass in motion and mass at rest.

Answer 7

I believe Einstein's theories show that travel at the speed of light is not possible. I'm sorry but I cannot remember the exact theory.

Answer 8

I don't see we can't.. many fictitious matters of the past in now a reality.

some examples:

Jules Vern's writings which are now happening.
cars before are ridiculed by horseback riders, now they are the main transportation.
the first flight,

as long as it is quantifiable, it is just a matter of when.
