    Crap is a dimension when you throw it at a wall, but it gains two additional dimensions on impact.

    no it isn't that's the opposite. One doesn't emit arrows. Maybe the smell of the blood. Animals have good smell. tracking something with seismic vibrations is a practice. seismic probably travels at the speed of sound. so thats still 7 dimensions not 8 with seismic. movement would cause sound seismic and gravity waves where as energy would cause all radiations emitted by a person.

    if the object in question creating the coordinates is moving then its x,y,z coordinates are constantly changing while its moment in time begins to slow down. If its at a standstill at x,y,z coordinates then the energy it emits can pinpoint its location. But, it doesn't matter because its moment in time depends on your distance from it just like smell.

    You obviously have no idea what "dimension" means and are just making shit up as usual.

    If I wanted to set up a meeting with you on earth I would need 4 coordinates, latitude, longitude, height (which floor the meeting was on) and time. That is all that is needed.

    If I wanted to meet with you and used your smell coordinate I would say something like; I would like to meet at 1 pm at the smell of fresh brewed coffee. Not very helpful is it?

    I don't understand how time which is determined by the energy an object emits is different then the sound or smell it emits. It EMITS these things they don't just turn around and travel into a tiny space that's small but not infinitely small. I think using the analogy of scheduling a moment by your watch or time is no different then if I find the church by its bell or am a dog that finds a squirrel by scent. There is a specific moment in time for any event whether you find something by smell or sound or your watch, however an object's time coordinate may not be the most or least accurate and doesn't always match the x,y,z, coordinates of the object its displaying if the object is far enough away.

    That's because you're working from false premises: time isn't "determined by the energy an object emits".

    In flat spacetime there is a constant that appears in many guises - call it k(constant). As a result of the remarkable properties of light it is generally accepted that (where c is the speed of light) it is found that c=k. If light travelled in the same way as sound (or smell) this wouldn't affect the k(constant) but c(the speed of light) and k(constant) would not be the same. Over reliance on "the speed of light" in explanations of spacetime can easily conceal more than it reveals.

    it is actually, but time is more fundamental than just the energy an object has .

    time is also based on movement of a thing ; in any direction . three dimensionally . interaction . with other things .

    Two objects that are both at coodinates x,y,z,t are co-incident. If any one of those four coodinates are different between the two objects, they are not co-incident.
    Such cannot be said about the light, sound or smells emanating from the objects.

    that's it that's why I said smell and sound, where are those two gonna go?
    you don't really need the time coordinate, If a dog finds me by smell he does it at any moment he pleases. If I am to meet your grandma, and she has terrible flatulence. then the clock created by her smell is also jive'n when I arrive. If you go faster then the speed of sound then you can listen back on the sound that was. hence when you jump in the car with your friends and drive past some people with loud music the sound bends.

    What you actually wrote was "I don't understand how time which is determined by the energy an object emits is different then the sound or smell it emits".
    Time is not determined by the "energy an object emiss" nor is determined by any sound or smell it emits.

    Wrong.
    Both you and the dog have to be in the same location at the same time any meeting to take place.

    There is no "clock created by her smell".

    Pure drivel.

    But what causes these objects to be at any coordinates ?

    The definition of a coordinate system which gives every possible location in space-time a particular quadruple of coordinates.

    In this case, the world line of the object would pass through the point-like event identified by the coordinates.

    If two different objects both passed through the same point-like event identified by the particular coordinates, that event would be synonymous with the intersection of the two world-lines.

    Sure

    But what are you proving ?

    Great answer Dwids. I get so much smarter everytime you talk so please, keep the useful information coming!

    Time is based on energy that causes movement of either a object or more than one object . And any combination there of .

    Two objects or five objects in space that do not move for infinity ; has no time.
