You got me. I misspoke (or miswrote) I meant inertia increases.
Both of you are wrong, the laws of relativity do not favor either, you can have an inertial deceleration and acceleration. Inertia is the resistance of acceleration and deceleration without the influence if an external force.
I don't believe a word you say dmoe...You are not fooling anyone.
But anyway for others that might like some possible explanation of your gobbldydook.......
[1] My twin paradox [no real paradox anyway] is a specific example that a GR expert relativist relayed to me.....
[2] The travelling twin experiences 12 months passage of time, both by physical clocks on his ship and biological.
[3] The passage of time that passed on Earth [IN THIS EXAMPLE] was around 225 years
[4] The passage of time is as per normal from each twins persepctive, within their own FoR.
[5] Therefor the stay at home twin has a much larger passage of time [225 years] then the travelling twin [12 moths]
Yes yes dmoe, we all realize [well most of us do] that the stay at home twin would also be obviously dead.
With your last highly confused statement, no no one has done it yet...Who said any different?
You need to lighten up and realize that what we see as science fiction today, may well be fact tomorrow.....
I have given plenty of examples of that fact, yet as per your usual style, you chose to ignore
What you believe is nether here nor there...it is not against any known law, and given TIME, again and given TIME, and once more given TIME, may well be achievable by some advanced earthly civilisation in the future.
paddoboy, you speak of "gobbldydook".(???!!!)
paddoboy, you speak of my "last highly confused statement".(???!!!)
paddoboy, how would you describe your last statement, in your Post #443, as follows ???!!! :
BTW, paddoboy, the reason that I am "not fooling anyone", is simply because I am not attempting to fool anyone!
paddoboy, your conduct in your Posts on this Forum, is...well...
All I can say is... If I were to respond in kind to your Posts - I would get Banned!
I would describe it as an emphasis supporting the many aspects of time , that are not against any known law, and may be achieved by some highly advanced Earthly civilisation....GIVEN TIME
Or do you really believe we are as a species, destined to stagnate on this fart arse little blue orb?
But just a question for you....
You have been pulled up before with your incessant pedalling of pedant meaningless nonsense, especially concerning me.
The following is a good example......
I mean fair dinkum dmoe, that is nothing short of moronic.
What sort of picture are you trying to reflect of yourself.
Bozo the clown wouldn't get a laugh that would compare to that.
Do tell?
So...the crowd now erupts in gut busting laughter?
paddoboy...Time Travel is Science Fiction!
And the utter confusion continues.......
Now there are four examples of showing how you misinterpret all and sundry....and there are probably many more, but not paying as much pedant detail as you, I'll settle for the four most recent.
You really seem to be getting to a desperate stage dmoe.
@ paddoboy
You quote 4 of your own Posts as examples of how I "misinterpret all and sundry..."!
You are, of course right, paddoboy!
Time Travel is Science Fiction! So...Note the time of this Post!
Edited to show that any Posts can be edited after they are Posted - but Time Travel is still Science Fiction!

????????? Wow!!!!!
Nuff said...except of course today's science fiction is tomorrows science fact, coupled with the knowledge that the laws of physics and GR do not forbid it, and that knowledgable people in reputable companies are researching all aspects of alternative propulsion systems, space/time warpage and manipulation, and the possible time travel spin offs.
Not real sure what you are on about, so I'll give you the benefit of the doubt.....
Here's an earlier post of mine [438] and there are probably many more......no editing at all.
But, yes my posts are edited after posting probably more times than not, due to my fairly heavy domestic agenda and the inevitable rush in typing and consequently spelling and grammar mistakes I need to fix up....that coupled with your own confusing misinterpreted posts,that need clearing up.
Read the following r-e-a-l-l-y s-l-o-w-l-y :
Scroll up and re-read your Post #447!
In your Post #447 - You quote 4 of your own Posts as examples of how I "misinterpret all and sundry..."!
Time Travel is still Science Fiction!
Good-Bye, paddoboy.
Yep, of course I quoted those posts [and there is many more of them] because you claim I'm saying time travel is not science fiction but fact.
That's not true, and is just another example of how you are apt to confuse what you read, or grossly misinterpret what you read, as was also recognised in the science methodology thread.
Obviously it is science fiction at this time March 2014......At least for human cargo. In reality though it is achieved every day in particle accelerators, and muon time frames.
But obviously that isn't what we are talking about...reading between the lines.
So in essence, and in line with the spirit of the thread, yes time travel at this time is science fiction.....Understood?
But nothing in the laws of physics and GR forbid time travel, and a possibility of some form of success is real in the future...understood?
And of course companies such as NASA JPL and John Glenn Labs are researching it along with other related concepts such as alternative propulsion methods.
Since you are unable to listen to me, I'll try another couple of links instead......

In the past few years, some scientists have used those distortions in space-time to think of possible ways time machines could work. Some like the idea of "worm holes," which may be shortcuts through space-time. This and other ideas are wonderfully interesting, but we don't know at this point whether they are possible for real objects. Still the ideas are based on good, solid science. In all time travel theories allowed by real science, there is no way a traveler can go back in time to before the time machine was built.
I am confident time travel into the future is possible, but we would need to develop some very advanced technology to do it. We could travel 10,000 years into the future and age only 1 year during that journey. However, such a trip would consume an extraordinary amount of energy. Time travel to the past is more difficult. We do not understand the science as well.
Actually, scientists and engineers who plan and operate some space missions must account for the time distortions that occur because of both General and Special Relativity. These effects are far too small to matter in most human terms or even over a human lifetime. However, very tiny fractions of a second do matter for the precise work necessary to fly spacecraft throughout the solar system.

From a pure physics point of view, travel into the future is not at all impossible and in fact happens all the . . . time. With all due respect to Doc Brown, however, backward time travel stacks up as a much tougher proposition.
"We can travel at different rates to the future," said Seth Lloyd, a professor of quantum mechanical engineering at the Massachusetts Institute of Technology. "To go into the past and mess around with it, that's more controversial."

Now its rather relevant to note that both Interpretations in both links basically say exactly what I have said in a different manner but the same ideas.
For you to recognise that fact is a long shot I realise, but just as you asked me, I now put it to you to read slowly...don't let anything get in the way of the obvious face value interretations and meanings
Then maybe we can both sit back have a beer and take it easy......
And being Friday night, and the footy about to start. I'm going to do that right now!

If time-travel is possible it will EVENTUALLY be discovered meaning time-travellers are here NOW! WHERE ARE THEY?
Where they always have been and always will be : firmly ensconced in the realms of Science Fiction!
First of all, a time travelling machine is equivalent to a transporter from Star Trek. You cannot just travel through time, you must travel through spacetime. If you went 24 hours into the past "where" would you be? In your same location? What does that mean? The Earth wasn't in that spot in any absolute sense 24 hours ago - you would likely be in the dead of space.
Anyway, my response to your comment is that, if backwards time travel ever becomes possible, it's more likely going to require a conduit at both points of travel to make this connection. We build one, wait ten years, then build another and travel 10 years into our past (to the point of the original invention). This would explain why we haven't seen anyone from the future yet.

Which would be the reason why planning to decelerate over the crest of a hill in a car helps you keep traction, get going quicker, and save gas.
That is not necessarily correct.
Firstly when we speak of the possibility of time travel, we can refer to things like "The Time Machine" from the movie, or the aspect of travelling at near relativistic speeds and returning to whence one came from as per the Twin paradox.
The first is pretty iffy, while the second remains a distinct possibility by a future advanced civilisation.
With the second scenario, no one logically would be able to go back any further then from the exact time that the traveller left for his journey anyway....So as yet we are unable to achieve near relativistic speeds to transport humans, so no one can as yet return.
If we look further into the scenario of time travel, it actually happens now in particle accelerators and sub atomic particles with very short lifespans, travelling to Earth, called muons...GPS also makes allowances for time dilation, and plane trips will also validate that fact.
The relevant point here, is that relativistic speeds are not obtained, so the effects are very tiny.
The Astronauts in the ISS also illustrate this fact.
