It sounds to me like you mean the theoretical Buzzard Ramjet starship. This design involves
a gigantic (hundreds of miles in diameter) force field scoop at the front, sucking in hydrogen
and then accelerating it out the back to produce thrust. This ship could reach 0.99999999c
but there are several problems:
1. At relativistic speeds flying through space hydrogen would be like flying through
liquid metal, remember hydrogen is an alkali metal in the periodic table
2. There is no known radiaition shielding capable of protecting the astronauts from the
amount of energy released by splitting the protons from the electrons
3. There is nothing that says we can't go faster than light, we just can't go at the
speed of light, only a ship made of light could do that
4. The scoop would have to be very large but not made of any physical material

My own theory for exceeding light speed involves creating/capturing several black holes of
equal mass and arranging them in a ring orbiting a common center of gravity. Feeding the black
holes electrical energy would give them electrical fields and hence a method of controlling
their movement via magnetic beams. Position a spacecraft far away at right angles to the plane
of rotation and then fire up the engines. As the ship accelerates towards the ring of black holes
you cause the ring's radius to begin to decrease. Timing is critical so that the event horizons
of all the black holes would overlap slightly at the same instant that the ship passes through
the center of gravity. Since not even light can escape a black hole, then the escape velocity
inside a black hole must be greater than c. By doing this the ship would briefly exceed c and
then shot out the other side to, who knows where? Of course, this requires magic box technology.

Too much O2 in the air and we get forest fires. Too much H2O = excessive humidity.
Too much CO2 = greenhouse effect. I read in The Weather Conspiracy that 50 years ago
Earth's atmosphere was 30% O2 and now it's only 20%.
