mindless rambling 2222222222222222222222222
Another train related question.
Imgine a larger circular rail track upon whcih there is a long train, so long in fact that the last carriage joins up with the front.
Wth me so far?
So next step is to do away with the carriage ends so you in effect one circular carriage on wheels on the track.
Still folowing?
Now put a circular rail track inside and another similar train on top. And repeat this.
Now the outermost train starts off to run at 500 mph. So the does train inside it and the one inside that and so on.
If you evauate air from each train expect for the smallest one wher you are sitting, you are only overcoming resistance in the driving gear so it
should be doable.
Given enough trains, you should be able to go faster than the speed of light.
So it that possible and could you do it on a budget of £ 250?

LOL!!!
The inner most train wont go any faster than the outer one...

LOL you are bonkers!
apart from the whole lot exploding from the G-forces, even if that could be overcome the trains that were nearing the speed of light would increase in
mass to the point of becoming immovable.
What you’re describing is the train equivalent of a multistage rocket!

Why?
You speed relative to the train outside yours is 500 mph, but is 1,000 releative to the one outside that one and so on.
Imagine the traisn are transparet and you are an observer looking at them,
Again you see outermost train going at 500, the one inside it even faster and so on.
You'll have to explain why.
Laws of physics? Do you believe these are set in stone waiting for mankind to discover them?
What I belive in is the Kantian viewpoint in that we humans are the observers, see see stuff, come up with a theory to explain it that is either
proved or disproved.
Engery is not being created in this case so not sure how that applies.

Speed of light is roughly
6706I66Z9 mph
So you would need I34IZ34 trains within trains to reach the magic c.
Unfortunately assuming you could solve the small packaging issue of doing that I suspect the gravitational effect would be to instantaneously create a
dirty great black hole where you're track used to be.

What you need is a MagLev inside a vacuum tunnel. There was a show on Discovery Channel a while back with a floating tunnel a couple of 100 feet under
the surface with a vacuum connecting London and New York, the predicted something like 7000 miles an hour or something.
Relative to the speed of light if you turned the lights on a maglev doing 7000mph surly the light coming from the lights would be doing the speed of
light plus 7000

My mistake...
I kinda ignored the fact that each sepperate train was going at 500MPH....
Now it makes sence...
And yes.,..the laws of physics as we know them are bound to change at some point....

Assuming this experiment could be carried, I am pretty sure there is something in the theory of relativity that means you cannot exceed C.
just like if you could travel in a ricket at C and shine a torch out of the front window.,
Seems a trip to google land is in order.
I may be some time.

For a physical object this does hold true i.e. firing a gun from the train. However light does not behave in the same way, the speed stays constant.
So the light from the train traveling in the opposite direction would still be travelling at the speed of light NOT the speed of light plus 7000.
Dont ask how i know this.....too much late night/early morning TV i think

Ah, but the laws of relativity tells us that light always travels at 186k mps relative to the observers position, so no!

Thats what I just said
You can get quite close to C in experiments they use to smash atoms together

No, but the light would shift from the red end of the spectrum towards the blue.
This might cause a problem with signalling where a red stop light at the terminal might appear to be green

When I get home I'm gonna mock up my own mini experiment.
I'll get a big wheel for an elephant, then a smaller one for a bufallo, then an even smaller one for a gazelle, right down to a teeny tiny one
for the humble flea and see how fast that bad boy goes!!

only if its in a vaccum.
I always liked the way the speed of light is roughly a foot a nanosecond - yay imperial rules

Each train would see the subsequent one running at a slightly slower time rate. This effect would increase nearer the speed of light till in the end
just before one gets there time stands still. Thus preventing that last watt of power pushing it to light speed. At the same time is mass would be
almost infinite so yet again the attempt is foiled.
This does not mean all is lost. Space it's self seems to be able to move and expand at much higher speeds. For example the universe is reckoned
to have jumped in size from smaller than an atom to larger than the Milky Way in a fraction of a second just after the big bang. What's more
quantum physic’s has shown through particle entailment that information can travel by some unknown means instantly to any point in space, this has
been proven experimentally. It has also been shown that space/time can be dragged around by rotating planets and even moved by the presence of high
energy light, opening up the possibly one day of space travel by space/time distortion, also more commonly know as warp drive.
It is always unadvisable to say things are impossible rather say, we don't know yet.

<personal nit>
The ancients never thought the earth was flat, navigation would have been impossible and someone would have noticed the horizon curves out at sea - in
other words it's a bit bl**dy obvious we live on a big ball.
The whole notion that the ancients believed on a flat earth was invented in 1828 by Washington Irving's publication of The Life and Voyages of
Christopher Columbus.
In other words the whole thing is a modern conceit.
