Why does twin who Travelled through space look younger after 60 years than the twin that remained on Earth?
After all, the twin on Earth can invoke time dilation: Moving clocks go slower, and so do the clocks of the moving twin. On these slower-moving clocks – and, by extension, in the whole spaceship – less time passes than on Earth, in other words: when the travelling twin returns, he is younger.
What is a paradox in science?
A paradox is an apparently true statement or group of statements that leads to a contradiction or a situation which defies intuition. The recognition of ambiguities, equivocations, and unstated assumptions underlying known paradoxes has led to significant advances in science, philosophy and mathematics. …
What is a scientific paradox?
It is a statement that, despite apparently valid reasoning from true premises, leads to a seemingly self-contradictory or a logically unacceptable conclusion. A paradox usually involves contradictory-yet-interrelated elements that exist simultaneously and persist over time.
How can the twin paradox be resolved?
The so-called “twin paradox” is easily resolved by noting that there is a physically meaningful disinction between the experiences of the two twins during the trip. The Earth-bound twin remains in a single constant velocity reference frame the entire time while the traveling twin must accelerate to turn around and come home.
What is the second paradox?
The second paradox is a bit more technical, and really comes to the heart of what physicists mean when they talk about relativity. The entire scenario is based on the idea that Biff was traveling very fast, so time slowed down for him.
What is the effect of acceleration on a traveling twin?
The acceleration causes the traveling twin to change from one constant velocity reference frame to another and produces effects that can be measured locally by the traveling twin in the form of inertial forces that can knock things over, compress springs, and generally endow objects with weight.
When was the acceleration paradox first presented?
This paradox (in a different form) was first presented in 1911 by Paul Langevin, in which the emphasis stressed the idea that the acceleration itself was the key element that caused the distinction. In Langevin’s view, acceleration, therefore, had an absolute meaning.
