Strange Posted March 31, 2018 Posted March 31, 2018 Quote 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. https://en.wikipedia.org/wiki/Lorentz_factor Are there any particular aspects that you need more explanation of?
MaximThibodeau Posted March 31, 2018 Author Posted March 31, 2018 What is happening to the quantity that is acceleration when the object is close to light speed ? I mean, why when we push on the acceleration pedal we actually slow down, close to light speed ?
Strange Posted March 31, 2018 Posted March 31, 2018 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)
michel123456 Posted March 31, 2018 Posted March 31, 2018 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.
MaximThibodeau Posted March 31, 2018 Author Posted March 31, 2018 So i will, in my referential (rocket), go over the speed of light ? 1 hour ago, michel123456 said: I am not an expert on this, someone else will correct me.

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: link deleted

[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? 1 hour ago, MaximThibodeau said: I took it from his own work 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.

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.
MaximThibodeau Posted March 31, 2018 Author Posted March 31, 2018 4 minutes is not enough to have read it?

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.
