How can you declare the answer is a 'yes' with no proof and no links to any proof. This is just hear-say and I thought there were rules on this site not allowing unsubstantiated statements like this?
Quick Thoughts:
Considering two equal masses and a small test mass midway between these, then yes, there will be a point of unstable-equlibrium. In a real situation, any minor deviation from this point would cause the test mass to move to the nearest large mass.
There will be a plane...
A point charge traveling at velocity v wrt to an observer will create 'rings' of magnetic field strength B centered along the axis of travel.
The magnitude of B will be greatest when the particle is at nearest distance to the Observer (O)when it path is at a right angle to O.
Using the...
Quote from link above:
If light always travels at c, how is it taking 'longer and longer'?
I see that light (and any other information) will be frequency shifted to be less energetic upon reaching the observer, but they still travel at c. The only other option is they don't emerge at all...
More questions!
In reference to StausX's reply:
Firstly, I think I have read that Einstein considered that the act of accelerating under say a rocket type propulsive force makes no time-dilation effect?
I also read a thread between 'MeJennifer' and 'Pervect' (I think?) where they were...
Yes, it is approx 8 minutes for light to travel from Sun to earth.
Now, assuming the Sun were Massive enough to collapse to a black-hole (I know it's not massive enough!), then how would the space-time curvature, already present, be up-dated?
I have heard Physicists talk on one-hand about...
It's hard for me to convey in writing what Iam trying to resolve, so I will try to be more precise:
In the post from Janus , he states the resultant difference in the Twins ages upon re-uniting is from the fact that B accelerates by turning around. There are 3 accelerations. The initial...
Another question.
I have another question:
In the scenario I described originally, If Twin B is traveling along an extended baseline of Twin A which are populated by clocks that were previously synchronized using Einsteins method; would Twin B infact be seeing two types of time info...
A few thoughts/questions:
This is very helpfull. I was indeed missing this point.
Are these different (simplified) scenario's correct? (after B has reached rel v):
1) Instead of turning around B decelerates and stops w.r.t A's frame.
Result: B is still younger.
2) As above , but Twin...
Thanks for the replies.
I think I need to mull this over a bit before I reply much more at the moment.
But I'd just like to add this bit to see if you agree or not:
'O.K So far I have the conclusion that a measurement is only relevant to the observers point of view. So my analogy of a...
When I say 'real' I mean physically in that state. E.g. Muon lifetimes in the atmosphere are physically real and not 'just' observably real.
The twin (B) said to be changing inertial frames is not just observed as being time-dilated, he is physically 'really' time-dilated; wheras Twin A is said...
I have gone through the previous posts on the subject in this forum but still have an issue.
So please tell me what is wrong with my following (qualitative) reasoning:
Assume the standard paradox is replaced with:
Twin A at origin of x-axis in free space.
Twin B accelerates away to speed...
