1. ## Time Dilation with more than one observer

Thank you for all help, Will definitely be taking a look at that book.
2. ## Time Dilation with more than one observer

You answered it . Just wanted to confirm that this is the case. I would assume this is also true for Relative Velocity Time Dilation? E.X: Person A Stationery, V=0M/S, γ=1 Person B Moving, V=0.87 C, γ=2 Person C Moving, V= 0.97 C, γ=4 So does this mean that if Person C experiences 1 second of time, person B will experience 2? And at the same "time", will Person A Experience 4 seconds? Pictures are taken for a presentation that I will be giving to some High School kids soon. (Have to try to be funny or they will sleep). I actually will be mentioning that Jim will be is in the center of the biggest void discovered by mankind (CMB coldspot)
3. ## Time Dilation with more than one observer

I have been thinking recently about this, but I haven't really found a clear answer to this online. Almost all examples consider only two things, a stationary observer+Moving object. Now I wanted to know what exactly would happen if there was more than one observer, each one affecting spacetime differently (Through Gravity or Velocity), and each one can observe one another. As an example, let's remove velocity TIme Dilation and only use Gravitational Time dilation for now. Also, let's specify who exactly are the observers and where they are exactly. The first one is Tim. Tim is orbiting around a Supermassive black. His clock will be ticking the slowest The second one is Kim. She is on Earth. Her clock will be ticking on Earth's Scale The third is Jim. Jim is in the center of a big void area (Affected mostly by his own gravity). His clock will be ticking the fastest Now let's assume they can "observe" each other "Simultaneously" Now to Kim, Tim should seem like he's traveling into the future. To Jim, Kim would also seem like she's traveling into the future, but at the same "time", Jim would also see Tim as he's traveling into the future, but because of the gravitational differences between each other, technically speaking, Jim should see Both Tim and Kim as traveling into the future, but he would see Tim as he's traveling into the future more so than Kim. It's a headspinner this one, so I've attached an illustration to explain my point. Let me know what you think.
4. ## Time and approaching the Speed of Light

Hi, I'm trying to make a presentation about light and would like to include some interesting facts when presenting. I'm not a physics or a physics major, so I need your help . From my understanding, the more energy driving an object with mass, the more spacetime warps. Now this got me thinking of something and I was wondering if this is true or not. Let's say we have three people. Person A, Person B and Person C. They're all at an Olympic stadium. Person A is on the stands and he's going to watch Person B and Person C race around the track. The race is set to an infinite number of labs. Person B has some sort of a superpower, and the energy driving him doubles every few seconds. Person C is just a regular runner. Now what from my understanding, Person B is going to accelerate faster and faster until he reaches 99.9% the speed of light. But as he the energy driving him increases further and further, spacetime should also warp. Now my question is, would Person B, eventually, warp space time so much that Person A (The guy in the stadium) would see him slowing down and Person B passing him, or would he hit the limit before then and becomes a blackhole? and if the limit never existed, would this happen? Appreciate your help!
