what is time? and how is it related to space?

Question

there was a show on tv that said that, on sub molecular level, there is no time.. does that mean that there is no space there?

Answer 1

Time is widely considered to be a dimension of our reality much similar to space. Objects travel through it at a certain speed, often dictated by their current speed going through space. Both can be affected by certain things such as gravity.

Imagine every object can move through a vacuum at the speed of light. The faster it moves through space the slower it moves through time. Two planets can revolve around the sun. If one spun round twice as fast as the other, time would be slower on the faster planet. However, people on that planet would experience time normally, but to observers on the other they would move in slow motion, whilst the slower planet would seem faster. It is thought that to objects travelling at light speed time stops for them, there is no energy left to move through time because it is all used to mvoe through space. This theory has come under attack with the recent developments of objects moving faster than light or the slowing of light, but so far the theory stays sound.

Answer 2

Absolute, true, and mathematical time, of itself and from its own nature, flows equably without relation to anything external, and by another name is called "duration"; relative, apparent, and common time is some sensible and external (whether accurate or unequable) measure of duration by the means of motion, which is commonly used instead of true time, such as an hour, a day, a month, a year.
Absolute space, in its own nature, without relation to anything external, remains always similar and immovable. Relative space is some movable dimension or measure of the absolute spaces, which our senses determine by its position to bodies and which is commonly taken for immovable space; such is the dimension of a subterraneous, an aerial, or celestial space, determined by its position in respect of the earth. Absolute and relative space are the same in figure and magnitude, but they do not remain always numerically the same. For if the earth, for instance, moves, a space of our air, which relatively and in respect of the earth remains always the same, will at one time be one part of the absolute space into which the air passes; at another time it will be another part of the same, and so, absolutely understood, it will be continually changed.

Answer 3

time is the fourth dimension. Time makes space to travel. Space travel on the path of time. If you change the time, the space will change in different dimension.
So, if you control the time, you have control of the change of space.

Answer 4

hey dude! nice ques....! time is a fhrame of reference with which u maeasure everything.for measuring any thing in this world it must exiat right??? for existance it must be gravitized.there is no objrct in this world without been gravitized.even the smallest of the objects are affliated to gravity.this is known as space time principle.but!!!!!!!! a photon has sometimes mass and aomrtimes in the form of waves!!!!!!!!!! man......... how cool quantum physics is!!!!!!!!!!!!!

Answer 5

Einstein said, "Time and space are modes in which we think, and not conditions in which we live"

Sometimes it is "now", and other times it is "now".

I met Richard Nixond once.

Answer 6

time is just another geometric dimension, the 4th one. it is related space through einstein's theory of relativity.
