Thanks.

Thanks.

So, distance isn't absolute but it depends at the speed of observer who makes measurements?

Does that mean my friend in tenth floor of building is moving relative to me if I am in first floor of building? Even if we do not move? Well, point A can be earth. Point B are me in first floor of building and point C is my friend in tenth floor of building. Earth rotates around it's axis, so...

We have 3 clocks A, B and C. They are in a straight line (Time 1). Clock A rotates around it's axis and clocks B and C rotates around clock A at distance L1 and L2 respectively. Distance L2 > L1. Clocks B and C rotates around clock A so they stay in straight line. Clock A rotates around it's...

Hi, here are image of situation. We have observer in point A. He have clock and know distance L between points B and C. He is observing rocket travel from point B to point C at speed near light speed. Can he calculate the speed of rocket using v = L / TimeA? In rocket at point B here are...

Hi, I have read Hafele-Keating experiment. Don't know if I understood it right. So I will try to explain how I understood it. Clock on Earth surface have speed v in space sum of Earth rotation about it's axis, rotation about sun, sun rotation and so on. Clock on flight going eastward will have...

This is exactly what I had in mind. If you make ruler in 20°C environment and measure size of object in 100 °C environment will it show size of object correctly? All materials have different expansion properties. So ruler size (length) will differ in 20°C environment and in 100 °C environment...

Really? Rubber sheet is so popular I was thinking it is standard in thinking. Even this video uses it. So majority of internet sources are misleading.

I mean this one https://www.google.lt/url?sa=i&rct=j&q=&esrc=s&source=images&cd=&cad=rja&uact=8&ved=0ahUKEwjdqZHDjpLQAhVJhSwKHQmADQAQjRwIBw&url=https%3A%2F%2Fwww.dreamstime.com%2Fstock-photo-space-time-gravity-image11748480&psig=AFQjCNFrtb59mb7LFZVpXPEzWzelsIbeDw&ust=1478452364975773

Yes. From watch youtube documentary movies I realized that it is very simplified and many things are missing. The same go with articles on blogs and similar. It is made so simple that if you start to think about it will start to make less and less sense.

Hi. Recently I was watching youtube about time and spacetime. And I have few questions about it. If I well understood no one knows what is the time. Here are no formulas to describe time. If it is true how we know if other watches measure time and not our perception on time which can be...
