A Light is shone out the side window of a spaceship ( moving close to light speed ), will the light still travel at the speed of light in the B axis?
A Light ( or laser ) is shone out of the side window of a spaceship ( which is moving as close to the speed of light as possible ), WILL THE LIGHT STILL TRAVEL AT THE SPEED OF LIGHT IN THE B AXIS ON THE DIAGRAM BELOW ?
NOTE - No one seems to have clearly answered the question ( although they do indicate a diagonal trajectory )
" WILL THE LIGHT STILL TRAVEL AT THE SPEED OF LIGHT IN THE B AXIS ON THE DIAGRAM BELOW ? "
NOTE - There is no need for the concept of the observer in this question, since the B axis is always the B axis .
* Also, if the light does continue travelling at the speed of light, IN THE B AXIS, but it also travels 'SIDEWAYS' in the axis that the spaceship was travelling ( AXIS A ON THE DIAGRAM ABOVE ) , would that indicate that light / photons have mass ( since I often read that light / photons have no mass ) ?
* Yes, surely I should think of this as the resulting DIAGONAL trajectory of the light, or should I, I have no qualifications in this area.
* [ I Should ask this in a different question - How would physicists consider this light when it hits an object ( maybe an object travelling as close to the speed of light as possible, but in the exact opposite direction that the original spaceship was travelling in ), could the light / photons hit an object 'SIDEWAYS', or will it be DIAGONAL, and could the combined speed of the impact cause the light to hit the object at a speed greater than the speed of light ( I know the answer is always no ) .
* Surely this has been answered in other questions, but it would be difficult to find .
NOTE - - I had deleted this question, due to an error I made in the question, I originally accidentally used the word 'PERPENDICULAR', when I intended to mean 'DIAGONAL'. This was a very significant error I made, and the results may still be present in one or more peoples answers . And, I have now also made a correction / clarification in the question title and initial description .
NOTE - I cannot post any comments, or reply to any comments, due to a technical problem which cannot be fixed. 275
