1. ### Sending Information at Relativistic speeds?

I just read this article: http://abcnews.go.com/Technology/plutos-majestic-mountains-atmospheric-haze-revealed-photo-horizons/story?id=33832751 The article itself is really cool, but something at the bottom of it caught my attention. I don't know how fast New Horizons is traveling, but say...
2. ### Time Dilation and Length Contraction

It was a question of IF that would work, not a declaration that it would work. And after playing with the equations I did see that it would not work.
3. ### Time Dilation and Length Contraction

That makes sense, and that's where my head is at right now, but I'm still unclear on how exactly that relationship works in relativity. And I'm still a bit confused. I was reluctant to do this, but I'm going to post the problem that led to this confusion in the homework section...
4. ### Time Dilation and Length Contraction

Find the proper length and multiply 1/##\gamma##. But I mean that's just me applying the formula from the book. I'm trying to understand it further than that. The book says the two(time dilation and length contraction) are closely related, but that's it, as far as I can tell, that's all it...
5. ### Time Dilation and Length Contraction

I know how to find them, but that's not really what I'm asking. I'm asking, COULD each be found directly from the other, given relative velocity? Or more generally:
6. ### Time Dilation and Length Contraction

I had a quick question about Time Dilation and Length Contraction. Are the two just different ways of measuring/describing the same effect? Or rather they both follow as a consequence from one another? i.e. I can find how much a length is contracted by finding the dilated time interval and...
7. ### Confusion about special relativity

@ghwellsjr: Thanks this reaffirms my understanding before I asked my professor that question. And now I have a follow up question to be sure I understand what's going on with time dilation. Here's an example given in class. I'll start with a crude version of the diagram given in class: We...
8. ### Confusion about special relativity

Thank you all, it seems the consensus is that either my professor was wrong, I misunderstood, or he misspoke. I'm thinking there was just lots of misunderstanding I'm the exchange. I haven't had a chance to read each response in detail, bit rest assured next time I get in front of my text book...
9. ### Confusion about special relativity

Maybe I misunderstood this, but if the light from both events reached my eyes at the same time, how would I conclude that the events took place 4 seconds apart?
10. ### Confusion about special relativity

So I just started taking Modern Physics and we are currently discussing special relativity. And needless to say, its giving me a headache. Here's my confusion: First, my Professor is Russian, and while his accent isn't so thick that I can't understand him, his grasp of English itself, is such...
11. ### What exactly is Time Dilation?

Ok, so I'm almost there then. I'll do some more reading and come back if I've got anymore questions. Thanks!
12. ### What exactly is Time Dilation?

Thank you both, I think I have what you two have described, but to be sure that I'm not starting from a misconception, I want to be sure that my interpretation is a valid one. So, in short, correct, or why not?
13. ### What exactly is Time Dilation?

So I know it has to do with reference frames and such, and I know that it is all about time relative to different observers, what I don't understand is how exactly is it that when you're moving at a speed close to 'c', you actually physically experience a different time interval than someone who...
