There is a guy named Mavis on a space ship. The space ship is at rest
and he measures the ship to be "60m" long. The ship then accelerates
to a speed of "0.8c", where "c" is the speed of light. Now, due to
relativity Mavis will no longer measure the ship to be "60m". Instead,
the length of the ship as measured by Mavis will be longer than "60m".

I'm sure you are all familiar with the equation

"l = 1/y * l_o"

where
"l" is the length of the space ship at rest and equals "60m"
"l_o" is the length of the ship travelling at "0.8c" as measured by
Mavis
"y" equals "1/sqrt(1-vē/cē)"

Now "1/y" equals "0.6".

So "l_0" equals "100m".

Now, Mavis can measure the ship in various ways. If he measures the
space ship using light signals he will find that the ship is "100m"
long. However, if he measures the ship with a ruler he will find that
the ship measures "60m". The reason why the ship hasn't expanded when
measured with a ruler is because the ruler *itself* has also expanded!

This leads to the Big Question:

the Big Question #1: Does this not contradict Einstein's first
postulate, the Principle of Relativity, which states that "the laws of
physics are the same in every inertial frame of reference." Because
obviously if Mavis can figure out what velocity the ship is travelling
at then there must be an absolute frame of reference, that is, a frame
of reference from which to measure the velocity of the ship.

Here's another way of looking at it:

We all are familiar with the fact that "relativistic mass" and "rest
mass" are related by the following equation:

"m_r = y * m"

where
"m_r" is the "relativistic mass"
"m" is the "rest mass"
"y" equals "1/sqrt(1-vē/cē)"

Let's say that we have a brick on a scale on the Earth. Right now it
weighs "3 kg". Now, what if by some extraordinary spacial event that
the Earth was sent out into space accelerating till is acquired a
velocity of "0.8c". Now, the relativistic mass of the brick will be "5
kg". The scale will definetely weigh the brick to be more than "3 kg"!
We again return to the Big Question:

the Big Question: Does this not contradict Einstein's first postulate,
the Principle of Relativity, which states that "the laws of physics are
the same in every inertial frame of reference." Because obviously if
Mavis can figure out what velocity the ship is travelling at then there
must be an absolute frame of reference, that is, a frame of reference
from which to measure the velocity of the ship.

Crucially this somebody will also see Mavis' ruler shrunk in the same
proportion as the spaceship itself.

A *guy* named Mavis?!? The only Mavis I know is the female of the species.

What about the late JP2? That was his name (though it might have been spelt
with a K) before he was elected.

The Marion who lives next door to me is definitely the female of the
species.

How about the wrestler Shirley Crabtree aka Big Daddy?
