Time and Space Indistinguishable - How Can This Be???

Suppose you had 2 inertial frames of reference, one stationary and one moving at the speed of light. It was once said that for the one moving at the speed of light that both the space and time axes of its spacetime diagram would become one, and that space and time would be indistinguishable. Although I (sort of) understand how the two axes would become one, I'm kind of confused how space and time would be indistinguishable within a frame moving at the speed of light. Intuitively, this seems to make no sense. If you step forward would you go forward in time, if you stepped backward would you go backward in time, etc.? How would a person experience such a frame? If someone could please explain this murky concept to me, I'd greatly appreciate it. Thanks!

Thanks for the reply Creedo, but, first of all, what's "space gravity magnetic mass"? Using two search engines, I couldn't find this term. Also, I was wondering, how would a person inside the light-speed frame of reference psychologically experience this frame of reference, especially as compared to a frame of reference such as
Earth? Thanks!
Youi wont find this anywhere except from aliens or me.

Got a privete e-mail then go to tec-time and contact me.

first off, one could NOT travel AT light speed, perhaps 99% of light speed, but if a ship ever reached light speed, it would become a black hole and you as its passenger might experience the mystical oneness of being merged with every atom, but not much more....
that is, if Einstein is correct about what happens at light speed...which so far tests indicate he is.
....so, assuming we are NOT at light speed, but just below it...and still seem able to breath, we would find that the seperation between us and home world <stationary object> is very close to a one for one ratio...for every near light second we move away from them, they age one second in their time. since light takes longer and longer to reach us, it would seem to us that they were the ones slowing down...to a near dead stop...when in fact we would be moving relative to them at the near dead stop rate...which would seem normal to us.
moving forward in the ship is moving in a direction which has been shortened so significantly that any measurements we make still puts us far less than light speed and so we never move outside any relativistic time frame...moving backwards in the ship does not change this either.
there is always an adjustment made for the spacetime velocity vector using a formula that contains squareroot of <1-velocity squared/lightspeed squared> or (1-(v^2/c^2))^-2
which always keeps us less than lightspeed relative to any other point in the universe.
what seems to be confusing many, they are taking a paper vector of time and mistaking it for an actual travellable thing like space...time is a dimension, that is a measurement, but not of a spacelike entity, but of relationships through space that vary with mass and speed. time travel is not a possibility because changing relationships cannot be reversed...the universe cannot be rewound by any machine which is within the universe.
