Is it possible to have objects faster than light in the universe?
The equation of mass is,
m = m_o / √ (1-v ^ 2 / c ^ 2)
Here,
m = relative mass
m_o = stationary mass
v = velocity of the object
c = speed of light
Now, we want to observe an object moving faster than light. That is, the value of the relative mass m of the object will be a real number. Because, this relative mass is the mass of the object relative to the observer. So if the relative mass is not real, then we cannot observe that object.
Suppose we want to observe an object that is twice as fast as light (2 c).
So, put v = 2c in the equation ...
m = m_o / √ (1- (2c) 2 / c ^ 2)
=> m = m_o / √ (-3)
=> m = m_o / √3i [i = √ (-1)]
As you can see in this last line, to get the real value of m, the value of m_o, that is, the fixed mass of the object must be unreal. ["Static mass" means the mass of the object relative to itself
Assuming, the stationary mass of the object is i3i kg. Let's put it in the equation,
Thus, m = 1 kg
That is, we are able to observe an object with a mass of i3i at twice the speed of light and a mass of 1 kg in this universe.
The stationary mass of the object was i3i kg. That is, the object has an unreal mass. So we can say that the object does not belong to our universe. Even if the object were moving at a speed less than light, we would not perceive the existence of the object. m) would be unrealistic. 'Unreal' means something that has no existence in our three-dimensional world.
That is, an object moving at twice the speed of the light we observe could be a high-level object ......
Thanks buddy wrote an important article I really need to know a lot
