With no drag in space, can we potentially accelerate an object up to the speed of light?

If NASA's deep space 1 craft could accelerate to 10,000mph given that it had constant power for 2 years, couldn't a bigger shuttle over time build up so much speed it catch's up with the speed of light? and what would be stopping it from accelerating further still?

By accelerating at 1 g (9.8m/sec^2), you would ';close in'; on the speed of light rather quickly. But don't forget about the mass that you would have as you near that speed. You could get very close, but you could never reach or exceed the speed of light.With no drag in space, can we potentially accelerate an object up to the speed of light?
The problem is,even in deep space,the vacuum isn't total. Hydrogen atoms of almost zero mass are still attracted to one-another,as they are the only gravitational masses within the attraction area of their respective molecules,but they WILL eventually meet. So,if light as a particle-wave has no mass,it will bend around any mass within it's path. You also have the question of-if light has had several billion years to travel


between point A and point B,why doesn't it keep on accelerating infinitely? The answer seems to be,because all known matter,wether of quantifiable mass or not,have an ultimate attainable speed,and that speed is the speed of light.
Look at Einstein's equations that have been proved quite well. At the speed of light, an object made of matter has infinite inertia and thus infinite mass, in effect, and its length in direction of travel becomes zero. So does time for it. There is not enough matter and energy in the universe or a googloplex like it to overcome infinite inertia, so material objects cannot closely approach the speed of light. They would also be squashed absolutely flat.

1) The speed of light in a vacuum is not the fastest speed attainable by something of mass in the universe. This has already been shown.





';But in an experiment in Princeton, New Jersey, physicists sent a pulse of laser light through cesium vapor so quickly that it left the chamber before it had even finished entering.';

Just like the article above states, ';However, our experiment does show that the generally held misconception that `nothing can travel faster than the speed of light' is wrong.'; It is a misconception that the speed of light is some universal speed limit.









You cannot reach light speed if you have mass.


You could keep accelerating and getting closer and closer to light speed, but never quite get there. Not to mention the ridiculous mass ratio that sort of constant acceleration would entail.
To accelerate to the speed of light, you would require infinite energy.
