Any object is there which can travel equal to or greater than light velocity?

Question

If any object is there which can travel greater than or equel to light velocity then we can prepare a space ship which can travel from one galaxy to another galaxy

Answer 1

No object with mass can travel at or faster than the speed of light in a vacuum.
However, the mere fact that we cannot travel at the speed of light in and of itself does not prevent us from building an intergalactic space craft....it just means that it will take significantly longer for the journey between galaxies to occur.
Even at the speed of light, as view from the Earth, a space craft would still take many thousands / millions of years to travel in between galaxies.

Answer 2

As far as we know at the moment no. But an interesting question. Based on current methods of calculation there are a number of problems, the massive increase in effective mass or density of the object should it exceed the speed of light and the association of the particles in the object with the speed of light or less suggesting the object would disintegrate. We have to be very carefull with laws, they by thier nature are created or worked out to explain conditions or effects that we can see, measure or experiment with. On this basis it is not correct to say somthing cannot happen if an existing law does not work for it. A good example of this is the change in laws or rules of aerodynamics when the speed of sound is exceeded.

Take a simplistic situation, a long pole with one end secured to a pivot point, if the halfway point is rotated with an effective linear velocity of the speed of light then the free end of the pole will be moving faster so in simple terms it would seem possible.

As regarding the mass of an object at no time during the acceleration of an object normally does its mass increase so why should it when the speed increases past the speed of light?

The next problem is what forces are normally involved in accelerating an object, friction or resistance against and the motive force to cause acceleration. Friction or resistance is caused by somthing else being in the space you want to go to so the simple awnser is to remove it or do it in an environment were the resistive material does not exist, how to do that??

Once this is achieved acceleration is considered, a large amount is required and the limiting factor is how quickly this can be applied. This really is the integrity of the structure of the object and its contents under acceleration.

So meet the criteria and why not?

Go to http://en.wikipedia.org/wiki/Special_relativity and you'll have a lot of informations to answer this question. Can not paste the image but i'll paste the text. Then you can go to wikipedia.


Causality and prohibition of motion faster than light

Diagram 2. light coneIn diagram 2 the interval AB is 'time-like'; i.e., there is a frame of reference in which event A and event B occur at the same location in space, separated only by occurring at different times. If A precedes B in that frame, then A precedes B in all frames. It is hypothetically possible for matter (or information) to travel from A to B, so there can be a causal relationship (with A the cause and B the effect).

The interval AC in the diagram is 'space-like'; i.e., there is a frame of reference in which event A and event C occur simultaneously, separated only in space. However there are also frames in which A precedes C (as shown) and frames in which C precedes A. If it was possible for a cause-and-effect relationship to exist between events A and C, then logical paradoxes would result. For example, if A was the cause, and C the effect, then there would be frames of reference in which the effect preceded the cause. Another way of looking at it is that if there were a technology that allowed faster-than-light motion, it would also function as a time machine. Therefore, one of the consequences of special relativity is that (assuming causality is to be preserved as a logical principle), no information or material object can travel faster than light. On the other hand, the logical situation is not as clear in the case of general relativity, so it is an open question whether or not there is some fundamental principle that preserves causality (and therefore prevents motion faster than light) in general relativity.

Even without considerations of causality, there are other strong reasons why faster-than-light travel is forbidden by special relativity. For example, if a constant force is applied to an object for a limitless amount of time, then integrating F=dp/dt gives a momentum that grows without bound, but this is simply because p = mγv approaches infinity as v approaches c. To an observer who is not accelerating, it appears as though the object's inertia is increasing, so as to produce a smaller acceleration in response to the same force. This behavior is in fact observed in particle accelerators.

Answer 4

The major problem with accelerating anything to the speed of light is it's inherant mass caused by whatever composite atoms it may be made of. The thing about light, or whatever particle light may be since we don't know for sure, is that it weights a lot less than even a single atom. Many million times less. There's no single material or object in the universe that could be as light as a light particle (no pun intended). It may be theoretically possibly to produce enough force to push an object to the speed of light, although it would take a huge amount of energy and a long time to accelerate to such a speed. We know that objects can be pulled at such great velocities through gravity (black holes for example can pull in even light particles).

Answer 5

U are on a spaceship that is equipped for a very long trip. No nothing travels at or near the speed of light except the material collapsing in a star that creates a black hole. As the gravity well increasees thing speed up and the mass begins to increas until it reaches infinite in mass which is the center of a black hole at the center of a Galaxy.

Answer 6

many people say no to this question,,,but i can give u an example.our computer has a speed of say 2ghz or 3 ghz.
this means that it can perform 2x 10^12 calculations in 1second.
sp the time taken by it to perform 1calculation is 1/(2x10^12) sec
during this the electronic signal might have to travell say 10 meters on wire.
therefore the speed of the signal is 10/ [1/(2x10^12) ] m/sec.
that comes out to be 2x10^13 m/sec which much more than speed of light....

Answer 7

As far as I am aware, it is theoretically impossible, given current thinking in physics, to travel at or beyond light velocity.

Spaceships travelling at warp speed... the stuff of science fiction.

However, researchers are currently looking at ways and means to bend space/time, thus making travel possible between galaxies. However, that, as far as i am aware, is centuries, even millennia, into the future.

But then, who knows?

Answer 8

Firstly discover what connects light with mattery. Then find a way how to change one into another and back again to its form. Find a way how to control the change with mathemathical perfection (sounds imposible - Gods restricted part it seems). Build that device with today greedy and argueing people in today economy and buroccracy system (laugh, that is for sure imposible, you must be imperor or at least his scientist to make what you want). You better estimate how many thousands of years will pass away if we survive and technology will go unstopable trough history into new eras of human nation. It seems you like sf with rational attitiude to posible inventions shown in them. Maybe I am the same... But I am more a sick realist. Maybe because I live in Poland. Many my dreams burried there, you know...

Answer 9

We have here
E = (M^2) * v
and the velocity equal the velocity of light so
V= C
E= (M^2) *C
M = root (E / C )
while C is too big so we must have an object infinitely small
No such object exist except the (photon) ..

Answer 10

No. The speed of light is the ultimate limiting velocity in the universe. Light (or other electromagnetic radiation) is the only thing that moves at that speed, and nothing moves faster.
