I dont think you understand what you are reading, saying water is less dense than air is ludicrous, "To go from moles to mass, multiply the moles by the formula weight of the compound.
Mass is not density.

I never said it was
Then why did you write about determing the mass of water and oxygen when the question was about the density?
Density is not weight.
And weight isn't mass. Edited by DrJones*, : No reason given.

At rest relative to what?
The driver

Well if you are sitting in a chair in the mall and I walk past you I will observe you motionless relative to me.
No, learn some grade school physics. That is not how relative velocities works.It's not enough to bash in heads, you've got to bash in minds soon I discovered that this rock thing was true Jerry Lee Lewis was the devil Jesus was an architect previous to his career as a prophet All of a sudden i found myself in love with the world And so there was only one thing I could do Was ding a ding dang my dang along ling long - Jesus Built my Hotrod Ministry Live every week like it's Shark Week! - Tracey Jordan Just a monkey in a long line of kings. - Matthew Good If "elitist" just means "not the dumbest motherfucker in the room", I'll be an elitist! - Get Your War On *not an actual doctor

Why does the driver observe the tracks going past him/her at 0.5 c?
Cause from her reference frame the tracks are going past her at 0.5c.It's not enough to bash in heads, you've got to bash in minds soon I discovered that this rock thing was true Jerry Lee Lewis was the devil Jesus was an architect previous to his career as a prophet All of a sudden i found myself in love with the world And so there was only one thing I could do Was ding a ding dang my dang along ling long - Jesus Built my Hotrod Ministry Live every week like it's Shark Week! - Tracey Jordan Just a monkey in a long line of kings. - Matthew Good If "elitist" just means "not the dumbest motherfucker in the room", I'll be an elitist! - Get Your War On *not an actual doctor

Bur what causes the tracks to go past her at 0.5 c?
Did you forget the experiment that you proposed?It's not enough to bash in heads, you've got to bash in minds soon I discovered that this rock thing was true Jerry Lee Lewis was the devil Jesus was an architect previous to his career as a prophet All of a sudden i found myself in love with the world And so there was only one thing I could do Was ding a ding dang my dang along ling long - Jesus Built my Hotrod Ministry Live every week like it's Shark Week! - Tracey Jordan Just a monkey in a long line of kings. - Matthew Good If "elitist" just means "not the dumbest motherfucker in the room", I'll be an elitist! - Get Your War On *not an actual doctor

Are you saying reality has nothing to do with a thought experiment?
He's saying that because it's just a thought experiemnt we don't have to worry about irrelevant details such as, how the driver survives travelling at 0.5c in a vaccum. How do the vital signs of the driver affect the physics under discussion?It's not enough to bash in heads, you've got to bash in minds soon I discovered that this rock thing was true Jerry Lee Lewis was the devil Jesus was an architect previous to his career as a prophet All of a sudden i found myself in love with the world And so there was only one thing I could do Was ding a ding dang my dang along ling long - Jesus Built my Hotrod Ministry Live every week like it's Shark Week! - Tracey Jordan Just a monkey in a long line of kings. - Matthew Good If "elitist" just means "not the dumbest motherfucker in the room", I'll be an elitist! - Get Your War On *not an actual doctor

So the only physics we are discussing is, does the photon travel in a straight line from the point emitted by the laser pen?
So why woud you bring in the question of how does the driver survive in the vaccum?
Either it does or does not there is no inbetween. Would you care to explain to me how postulate #2 can be true and the photon miss the detector?
I think we should get you understanding grade school physics before we move onto more advanced topics.It's not enough to bash in heads, you've got to bash in minds soon I discovered that this rock thing was true Jerry Lee Lewis was the devil Jesus was an architect previous to his career as a prophet All of a sudden i found myself in love with the world And so there was only one thing I could do Was ding a ding dang my dang along ling long - Jesus Built my Hotrod Ministry Live every week like it's Shark Week! - Tracey Jordan Just a monkey in a long line of kings. - Matthew Good If "elitist" just means "not the dumbest motherfucker in the room", I'll be an elitist! - Get Your War On *not an actual doctor

When you declare the car's reference frame at rest...
We're not declaring the car's reference frame to be at rest. The car's reference frame is the frame in which all other velocities are measured relative to the car. This is high school physics.It's not enough to bash in heads, you've got to bash in minds soon I discovered that this rock thing was true Jerry Lee Lewis was the devil Jesus was an architect previous to his career as a prophet All of a sudden i found myself in love with the world And so there was only one thing I could do Was ding a ding dang my dang along ling long - Jesus Built my Hotrod Ministry Live every week like it's Shark Week! - Tracey Jordan Just a monkey in a long line of kings. - Matthew Good If "elitist" just means "not the dumbest motherfucker in the room", I'll be an elitist! - Get Your War On *not an actual doctor

That says all inertial reference frames are moving and nothing about one of them being stationary or being able to declared stationary and cause them to cease their constant straight line motion relative to one another. Take reference frames A, B and C.Frame A is moving at +15 m/s. Frame B is moving at +45 m/s parallel to frame A. Frame C is moving at -45 m/s parallel to frame A. Frame B's velocity relative to A is +30 m/s. Frame C's velocity relative to A is -60m/s. this is high school physics.It's not enough to bash in heads, you've got to bash in minds soon I discovered that this rock thing was true Jerry Lee Lewis was the devil Jesus was an architect previous to his career as a prophet All of a sudden i found myself in love with the world And so there was only one thing I could do Was ding a ding dang my dang along ling long - Jesus Built my Hotrod Ministry Live every week like it's Shark Week! - Tracey Jordan Just a monkey in a long line of kings. - Matthew Good If "elitist" just means "not the dumbest motherfucker in the room", I'll be an elitist! - Get Your War On *not an actual doctor

Is the car's inertial reference frame moving at a constant 0.5 c speed relative to all other inertial reference frames?
All other reference frames? No. Some reference frames? Yes.
But the car inertial reference frame does move at a constant 0.5 c relative to all other inertial reference frames.
As above: false
Does that mean there is no such thing as a stationary object?
It depends on what reference frame you use.
So why can I find all kinds of different views expressed in so many different books written by so many different authors?
We're no longer arguing relativity, we're still trying to get you to understand stuff that was figured out hundreds of year ago.It's not enough to bash in heads, you've got to bash in minds soon I discovered that this rock thing was true Jerry Lee Lewis was the devil Jesus was an architect previous to his career as a prophet All of a sudden i found myself in love with the world And so there was only one thing I could do Was ding a ding dang my dang along ling long - Jesus Built my Hotrod Ministry Live every week like it's Shark Week! - Tracey Jordan Just a monkey in a long line of kings. - Matthew Good If "elitist" just means "not the dumbest motherfucker in the room", I'll be an elitist! - Get Your War On *not an actual doctor

So how do you propose to overcome the restriction's put on the photon by Newton's first law?
What makes you think the photon is governed by Newton's laws of motion?It's not enough to bash in heads, you've got to bash in minds soon I discovered that this rock thing was true Jerry Lee Lewis was the devil Jesus was an architect previous to his career as a prophet All of a sudden i found myself in love with the world And so there was only one thing I could do Was ding a ding dang my dang along ling long - Jesus Built my Hotrod Ministry Live every week like it's Shark Week! - Tracey Jordan Just a monkey in a long line of kings. - Matthew Good If "elitist" just means "not the dumbest motherfucker in the room", I'll be an elitist! - Get Your War On *not an actual doctor
