  • The mass-velocity relationship and the light speed speed limit.

    From LaurenceClarkCrossen@21:1/5 to All on Tue Mar 11 04:04:42 2025
    Even an infinitesimal particle approaching the speed of light would have
    enough momentum to go over the speed of light because its increasing
    mass would increase its momentum.

    The mass-velocity relationship would not ensure that the particle
    accelerates over the speed of light since the additional mass would not accelerate it.

    "The acceleration of an object depends directly upon the net force
    acting upon the object, and inversely upon the mass of the object. As
    the force acting upon an object is increased, the acceleration of the
    object is increased. As the mass of an object is increased, the
    acceleration of the object is decreased."

    This is not true in gravity free space.

    The more massive it became, the more rapidly it would orbit anything
    bigger than it until it moved faster than light. Some stars spin faster
    than light.

    Velocity is always 'relative', or 'frame dependent'.

    A particles has therefore no 'rest mass' and no 'absolute velocity'.

    To talk about velocity would require to say, in respect to what that
    velocity shall be measured.

    There are two obvious possibilities in respect to which the particles
    could be in motion:

    the observer
    the particle itself

    'The universe' is not possible as reference, because the universe does
    not contain points, which do not move.

    Usually the observer is regarded as being at rest and placed in the
    center of his won coordinate system, because the other possibility is a
    little pointless as the particle does not move in respect to itself.

    This does not mean that a particle or any object cannot exceed the
    observable speed of light.

    "There will therefore exist an unsurpassable limit speed that will
    extend to all particles and all the laws of physics".
    Doctor Richard Hachel.

    If you accelerate a body by only 10 meters per second (Earth's gravity),
    you will realize that after four or five years, compared to you, it will
    have already exceeded the speed of light by five times.

    But you will not be able to observe it moving faster than c.

    Your observation of the speed will "squeeze" more and more, according to
    the equation between the observable speed and the real speed:

    Vo = Vr / sqrt (1 + Vr² / c²)

    This is due to the inescapable nature of the relationship between space
    and time.


    No, this is due a crazy idea of an insane maniac.

    Momentum is locally conserved, i.e., there is no other way to increase
    momentum but to transfer from elsewhere.
