If a spaceship is traveling at 90% the speed of light on the X axis. And it is also traveling 90% the speed of light on the Y axis. What is its velocity?

Hi android34, welcome to PFandroid34 said:Morgan (l982) estimated that the exhaust velocity of a pion- relecting matter/antimatter rocket could be in excess of 0.9c. If the spaceship is a sphere, and one antimatter rocket is aimed in the X axis, and one antimatter at 90 degrees to X 1/4 the way across the sphere is aimed in the Y axis, and both push to 0.9c, is what you say still true?
Propulsion systems do not "push to [a velocity]"; they provide (a force which results in) an acceleration.android34 said:and both push to 0.9c, is what you say still true?
The choice of propulsion is largely academic, so lack of a reference is not a show-stopper. Any propulsion that can (theoretically) accelerate a craft to .9c will do. There are a few well-known ones that are unlikely to be contested.ZapperZ said:You need a better and more complete reference than that!

The vector drive uses a type of propulsion that manipulates space-time to create a "warp bubble" around the spacecraft. This bubble compresses the space in front of the ship and expands the space behind it, allowing the ship to essentially "ride" the wave and travel faster than the speed of light.
While the concept of faster than light travel using a vector drive is theoretically possible, it has not been proven to be possible in practice. Scientists are still studying and researching the technology to determine its feasibility and potential drawbacks.
One potential risk of using a vector drive for faster than light travel is the potential for collisions with debris or other objects in space. The warp bubble could also have unforeseen effects on the surrounding space or the ship itself. Additionally, the high levels of energy required for the drive could be dangerous if not properly contained.
The speed of a vector drive is not limited by the speed of light, so it is theoretically possible to travel infinitely fast. However, the amount of energy required to reach such speeds is currently beyond our technological capabilities.
One limitation of using a vector drive is the need for a large amount of energy to create the warp bubble and sustain it throughout the journey. This could potentially limit the distance and duration of travel. Additionally, the technology is still in its early stages and there may be unforeseen limitations or challenges that arise as it is further developed.
