We know so many fields like electric field, magnetic field, gravitational and radiation field. But ever wondered what are these field's speed ? We know no matter can be moved beyond the speed of light. But what about the field of that object ???
There is a field associated with every body which posses the
particular property like charge, magnetism, mass etc.. for electric , magnetic
and gravitational fields respectively... lets now consider gravitational field
as every thing that we can imagine posses mass. Now take a body of mass M
, and take our observation point as pt P. Now when this body is at distance
X from P, then the gravitation potential is G*M/(X*X) where
G is gravitation constant, now if this body is coming near to the point
P, the gravitation potential will increase accordingly... but a hypothetical
question arises when I say what will be the Expression when the body is moving
with speed near or more than that of speed of light ???
How the theory of relatively explains the field of a moving
body ???
Time, is it continuous or discrete ?
We can easily say without thinking much that the Time is
discrete
as we have watch, we divide time into many units, we have seconds, milliseconds
.... but is really time discrete or we are just making our job easier by assuming
that time is discrete ?
Answer to this question can be obtained by this question , when we throw any
object up in the air, how long does it stay in the top most position ? I mean
how long it has zero vertical velocity?
I can't answer this if you can answer this then please mail me, and hence I
consider the time continuous and not discrete...
