thank you for advice ; ithink you read much more than i did , but if a particle has the speed of light enter this hole . i suppose you can tell me what kind of physics or mathematics can describe its motion .

Many times we heard about black holes and other holes differs from one hole to another . assume we have a hole where this hole trans you from place to place , inside this hole we do moves a distance and let's called it (h) . if you want to use this hole to move from Earth to sun for example ...

okey . what is the difference when a satellite moves in the same plane which planets takes from one planet to another and a higher plane . this question has no sense , you may think , but think a bout the moon and the Earth and the sun and the light .

If we have two parallel plane in the space in addition to another two objects moving in parallel with the same velocity .what is the time for both. i mean does the time differe?

What is the meaning of floatin and flying and moveing freely in space?

What is the difference between the float and fly and move freely in space first, and within the Earth's atmosphere?

why the electron does not stick to the nuclei?

can i empty a wire from its free electron.

thank you very much LCKurtz.

thank you for reply. that's help.

the question gives just the initial and terminals points of the vector , nothing else. and thank you for reply.

thank you sethric for reply, but can not i calculate those vectors without drawing ?

vector 3D If i given a terminal and initial points of a vector in x,y,z positive plane . how to find three other vectors in the same plane having the same magnitude and the same direction and the same slope ?
