Could you use the formula "planck length/c=planck time" to convert time into a spatial distance? Using that to tell how far something is through time.

What's mass got to do with it?alw34 said:only for massless objects, like the photon
In the real universe, that may be true. I'm assuming flat space-time for simplicity's sake.alw34 said:they are never 'perpendicular'
Yes. Or you can use any units you like. For instance you can say that a typical human is about 7E17 m long in time compared to about 2 m long in height. The conversion factor is c in whatever units you use.mcjosep said:Could you use the formula "planck length/c=planck time" to convert time into a spatial distance?

He is talking about four-vectors, ##(ct,x,y,z)##. Where ##(1,0,0,0)\cdot(0,1,0,0)=0## indicates that time is perpendicular to space, although "orthogonal" may be a better word.alw34 said:they are never 'perpendicular'
No.mcjosep said:So could you say I am gravitationally attracted to something in a different time than right now and calculate that attraction by using this conversion formula and saying that length is the my radius to that object?
It is not clear from your question, but I assume that you are thinking of "calculate that attraction" being Newton's law of gravitation. Unfortunately, Newtonian gravity is not compatible with relativity, so that won't work. Instead you would need to calculate gravity using the Einstein field equations.mcjosep said:So could you say I am gravitationally attracted to something in a different time than right now and calculate that attraction by using this conversion formula and saying that length is the my radius to that object?
Time is often referred to as the fourth dimension alongside the three dimensions of space (length, width, and height). This concept suggests that just like space, time can be measured and represented as a coordinate in a four-dimensional space-time continuum.
Unlike the three spatial dimensions, time is one-dimensional and only moves in one direction - forward. While space can be measured in units such as meters or feet, time is measured in units such as seconds or years.
No, spatial length cannot be applied to time as they are fundamentally different concepts. While length refers to the physical distance between two points in space, time refers to the duration or interval between two events.
Time is a crucial component in many scientific theories, including Einstein's theory of relativity and the concept of space-time in physics. Time as a dimension allows for a better understanding of the relationship between space, matter, and energy.
No, time is not the only dimension that moves at a constant rate. While time moves forward at a constant pace, the other three spatial dimensions can change based on factors such as gravity and motion. For example, time may feel slower for someone experiencing stronger gravitational forces.
