Special relativity is a theory proposed by Albert Einstein in 1905 that explains how time, space, and motion are perceived differently by observers in different frames of reference.
0.95c refers to a speed that is 0.95 times the speed of light, which is approximately 299,792,458 meters per second. This is a very high speed and can only be achieved by objects with a huge amount of energy, such as particles in a particle accelerator.
According to special relativity, time appears to pass slower for objects traveling at high speeds. This means that for an observer on Earth, time would appear to pass faster for a spaceship traveling at 0.95c compared to a stationary object. This is known as time dilation.
Yes, according to the principles of special relativity, time dilation is a real phenomenon that has been observed and confirmed through experiments. It is an important factor to consider when dealing with objects traveling at high speeds, such as satellites and spacecraft.
Special relativity predicts that time slows down for objects traveling at high speeds. This means that astronauts on a spaceship traveling at 0.95c would age slower compared to people on Earth. This has been observed in experiments with atomic clocks on high-speed airplanes and satellites, and is known as the "twin paradox".
