Why the Lorentz factor?

The Lorentz factor or Lorentz term is the factor by which time, length, and relativistic mass change for an object while that object is moving. The expression appears in several equations in special relativity, and it arises in derivations of the Lorentz transformations. The name originates from its earlier appearance in Lorentzian electrodynamics – named after the Dutch physicist Hendrik Lorentz.

Are there any particular aspects that you need more explanation of?

It depends what frame of reference you measure the acceleration in.

For example, if you are in a rocket that is being accelerated at a steady 1g (comfortable) then without relativity, you would reach the speed of light in about a year.

But what actually happens is that the people back on Earth would see the rate at which your speed increases (your apparent acceleration) decrease. You can think of this being because your "relativistic mass" increases (and so the force of the rockets have less effect). Or you can say it is because velocities do not add linearly in relativity (because the Lorentz factor needs to be taken into account): http://hyperphysics.phy-astr.gsu.edu/hbase/Relativ/einvel.html

However, in your space ship, you would still feel 1g and so think you are undergoing constant acceleration.

Actually calculating acceleration in relativity is slightly more complex: https://en.wikipedia.org/wiki/Acceleration_(special_relativity)

I am not an expert on this, someone else will correct me.

What I understand is that the Lorentz transformation gives you what on observer measures when observing a moving object. It does not give you anything about your own motion (because motion is relative). So answering your question, no, you will be accelerating all the time.

But some observer far away will measure things bizarrely, like your mass increasing and your velocity never reaching Speed Of Light. Reversely, you yourself accelerating and looking back will measure the observer increasing in mass and never receding from you at velocity more than SOL.

So i will, in my referential (rocket), go over the speed of light ?

You cant get corrected, under the current theory, you are 100% right.

That's my problem:

unless, something, i don't understand, E <> Imaginery

I took it from his own work:

No.

I don't know where you got that equation from and the right hand part is not equal to the middle part.

It looks like you don't understand mathematics.

[math]1 - \frac{v^2}{c^2}[/math]is always positive so you can't get an imaginary result. So where do you get [math]I^x[/math] from, and what is x?

You will need to be more specific. I am not going to read 165 pages to find something you appear to have misunderstood.

And why not find a better source? I have always found Einstein's writings on the subject to rather obtuse.

Lets take a look to my theory:

Not unless you present it here, in the Speculations forum, no.

However, as you have no model and no evidence you do not even have a hypothesis, never mind a theory. You have some incoherent drivel and some nice pictures of cats. This is not science.

Sorry about my link, i did not know, but is this note is about the link of Einstein work too?

I removed links you identified as being to your work. If you want to link to Einstein's papers (e.g. "On the Electrodynamics of Moving Bodies"), that would be fine.

So now, with all those links remove, what still wrong? could i return to the main thread again

!

Moderator Note

What main thread? I didn't split this off from another discussion. I moved it here, because you are claiming mainstream physics is wrong.

I don't know what that means. Nobody watching?

If you refuse to address this, the thread will be closed

That's OK, I'm watching....I often get a laugh out of the number of Tom, Dick, and Harry's that come to a public forum, claiming that they have shown Einstein to be wrong. :D
