Under what conditions will two events appear to be simultaneous to all observers?
Section Summary. Two events are defined to be simultaneous if an observer measures them as occurring at the same time. They are not necessarily simultaneous to all observers—simultaneity is not absolute. Time dilation is the phenomenon of time passing slower for an observer who is moving relative to another observer.
What are 2 consequences of special relativity?
Special relativity had strange and unexpected consequences such as length of objects vary when measured in moving reference frames, mass cannot be accelerated to the speed of light and that time and space are not independent.
What is meant by observer in special relativity?
In special relativity, an observer is a frame of reference from which a set of objects or events are being measured. Usually this is an inertial reference frame or “inertial observer”. The effects of special relativity occur whether or not there is a sentient being within the inertial reference frame to witness them.
What is the main reason according to special relativity why two events as seen by different inertial observers may not happen simultaneously?
The two events were not simultaneous, according to the new observer. Notice that the reasoning requires the light postulate: both light flashes must move at the same speed; that is, each must require the same time to cover the same distance. The reasoning extends to the clocks.
What is meant by relativity of simultaneity?
In physics, the relativity of simultaneity is the concept that distant simultaneity – whether two spatially separated events occur at the same time – is not absolute, but depends on the observer’s reference frame.
What is special about special relativity?
The rules of special relativity are a special case of general relativity, where you can ignore the gravitational fields. The special advance of special relativity was combining the fact that the speed of light is constant with the fact that observers in all reference frames perceive the same laws of nature.
What can observers detect?
As observers can detect the state of other observers, placing two adjacent observers, each watching the other, can make a fast and compact redstone clock. They send out a pulse….Limitations.

What is an example of special relativity?
Another interesting result of special relativity is length contraction. Length contraction is when objects appear shorter the faster they are moving in relation to the observer. To give you an example of how objects moving very fast appear shorter.
What are the main principles of special relativity?
The special principle of relativity states that physical laws should be the same in every inertial frame of reference, but that they may vary across non-inertial ones. This principle is used in both Newtonian mechanics and the theory of special relativity.
