Are scientist doing anything about inventing something that can travel with the speed of light?

I mean more space mysteries could be better and easily solved if we could travel or send probe to these light-years-away planets. is there any hidden or current development going on around this topic?

nope, they say it can't be done
but i wish they would try

It's rather beyond our technological capabilities at present.

well theoretically if you travel at the speed of light you will be demolecularised, and so therefor you cannot travel to the speed of light

and by the way, the scientists are working hard on an antimatter based programme to propel futuristic spacerockets

I think there are many other obstacles to overcome before we even begin thinking about the speed of light. Like, maybe getting to 1% the speed of light first. The big problem is energy use. The nice little equation e=mc^2 which also states the closer to light speed you get, mass increases, meaning it would take even more energy, so right at c would take an infinite amount of energy. So with traditional propulsion, it is not possible. However there are some theories like worm holes and warping of space that may get around that.

I believe N.A.S.A. has an advanced propulsion department that is working on the situation, i'll give you a few links so you can see some of the idea's for faster than light propulsion.

Theres plenty of ideas thrown around at the moment, but no real proposals for funding or serious experiments. One idea thats showing promise is Buckhard Heims work, which, while utter gibberish for someone like me, apparently makes a whole lot of sense to more educated people.

Michael J wrote of the formula e=mc^2, but a better formula to describe the increase of mass as v approaches c (v -> c) is

e= mc^2 / sqrt (1 - v^2/c^2)

As v -> c, the denominator approaches 0. Dividing something by zero is undefined, but approaches infinity.

Not really. The fuel requirements for speeds like that defy the imagination. If we were to use chemical rockets like the shuttle's we would need more fuel than there is mass in the universe for an interstellar journey of 900 years. A nuclear rocket would require a million supertankers worth of fuel. A fusion powered rocket would require a thousand supertankers. The power requirements are seperate and are equally as high. And high speeds involve seriously high risks. Space is not a complete vacuum. Space is littered with stuff. Not that much to be sure, but there are considerable quantities of interstellar hydrogen and the occasional particle of matter. Just running into the hydrogen at relativistic speeds would yield LOTS of radiation. Run into a sand sized particle of matter and the resulting explosion would be of a nuclear sized yield.
We have no expertise in life support. Long interplanetary and interstellar journeys would require almost 100% recycling of air, water, and human waste. You simply cannot carry enough supplies. A rather strange organization with fantastic funding performed the BIOSPHERE II project some years ago. They constructed a huge environment under glass that should have allowed their researchers to survive in an enclosed environment. It didn't. As soon as the doors closed the environment inside went south. It was a major fiasco. The US hasn't attempted anything similar. Until we can build completely self-sustaining environments, long space journeys are almost impossible.

You need to study the theory of relativity. No matter can travel anywhere near the speed of light, because inertia increases exponentially at higher speeds. One could burn the rest of the universe to power a rocket and still not achieve light speed. In effect, at the speed of light, the rocket's mass would be infinite, its time would be zero and so would its length in direction of travel. Einstein gave us equations that show us that. Do you understand now that scientists do not waste time on impossibilities, e.g. a rocket travelling at the speed of light?
