An outside observer will perceive my spaceship as being shorter, but what will i see of my outside surroundings? Will they be longer?
Depends what you mean by perceive. He certainly will not actually see it shorter. Only when he draws a choordinate chart he will conclude it is shorter.sodaMay said:An outside observer will perceive my spaceship as being shorter, but what will i see of my outside surroundings? Will they be longer?
In relativity there's a difference between what you see visually and what you measure in your own rest frame. What you see is affected by the fact that light from different events (or different parts of a single object) takes different amounts of time to reach you; the coordinates you assign to events are based on compensating for such delays, the usual method being for each observer to use a network of rulers and synchronized clocks at rest relative to himself, and defining the coordinates of events purely in terms of local measurements on this system (for example, if I see an explosion happen next to the 12-meter mark on my x-axis ruler, and the clock sitting on that mark reads 5 seconds at the moment the explosion happens next to it, then I assign that event coordinates x=12 meters, t=5 seconds in my frame).sodaMay said:An outside observer will perceive my spaceship as being shorter, but what will i see of my outside surroundings?

The visual effects are symmetric. The 'distortion' seen by the outside observer as he looks at your spaceship will be the same as the 'distortion' seen by you as you look outside.sodaMay said:An outside observer will perceive my spaceship as being shorter, but what will i see of my outside surroundings?

Terrell's paper pointed out that although special relativity appeared to describe an "observed contraction" in moving objects, these interpreted "observations" were not to be confused with the theory's literal predictions for the visible appearance of a moving object. Thanks to the differential timelag effects in signals reaching the observer from the object's different parts, a receding object would appear contracted, an approaching object would appear elongated (even under special relativity) and the geometry of a passing object would appear skewed.
I'd say the relativistic Doppler effect is the closest analogy; because of this effect, a clock moving towards you will visually appear sped up rather than slowed down, and a clock moving away from you will visually appear slowed down by a factor greater than the time dilation factor.Naty1 said:I had forgotton reading about this for the first time about a month or so ago and never got to post the obvious question: Is there an analogous effect for time dilation? Why?
Spaceships use advanced technology such as rocket propulsion, navigation systems, and life support systems to travel through space.
Yes, you can see stars and planets while journeying in a spaceship. However, the view may be different from what you see on Earth due to the lack of atmosphere and other factors.
The time it takes to reach a destination in a spaceship varies depending on the distance and speed of the spaceship. It can take anywhere from a few days to several years to reach a destination.
Journeying in a spaceship can be risky and requires extensive training and precautions. However, with advanced technology and proper safety measures, it can be relatively safe.
Some of the challenges of journeying in a spaceship include exposure to radiation, potential equipment malfunctions, and the physical and psychological effects of being in a confined space for an extended period.
