Challenge: superluminal average speed

In summary, the conversation discusses the possibility of achieving superluminal speed and reaching Andromeda in one's lifetime, but clarifies that distance in an accelerated frame cannot simply be added. Therefore, distance and time are not directly proportional and cannot be divided to determine speed.

This is good one! I like it.

So for practical purposes an answer to your question is YES, in can achive a superluminal average speed and reach Andromeda in your lifetime.

But strictly speaking, in an accelerated frame can not simply add distances measured when you were moving at different speed. So distance becomes non-additive. Hence you can not just divide the total distance by time.

To clarify, asking about the distance Da (in a rest frame of observer A) covered by observer B in his proper time Tb, then Da/Tb can be >> c, but as you see it is a clear mixture of data from different observers and frames.

היא תופעה פיזית שמתארת את המהירות המקסימלית שבה חלקיק יכול לטייל בחלל. על פי תורת היחסות הכללית של איינשטיין, אין אפשרות לעבור את מהירות האור ולכן כל חלקיק עם מסה גדולה יותר מאפס לא יכול להגיע למהירות גבוהה יותר מהמהירות האור.

למרבה המזל, תורת המוצא הכללית גם מאפשרת לפנות את חלקי האנרגיה של החלקיק למהירות גדולה יותר ממהירות האור. זה מתאפשר על ידי יצירת חלל זמן, שבו החלקיק יכול להתקדם יותר מהר ממהירות האור. אך גם זה מתאפשר רק במקרים מסוימים ולא ניתן להשתמש בו כדי להשיג מהירות גבוהה יותר ממהירות האור בצורה קבוע
 

Related to Challenge: superluminal average speed

1. What is superluminal average speed?

Superluminal average speed refers to a theoretical concept in which an object travels faster than the speed of light, which is considered the fastest possible speed in the universe according to the laws of physics.

2. Is superluminal average speed possible?

Currently, there is no evidence or scientific theory that supports the possibility of achieving superluminal average speed. The laws of physics, specifically Einstein's theory of relativity, state that the speed of light is the maximum speed at which any object can travel.

3. What are some examples of objects or phenomena that can travel at superluminal average speed?

Currently, there are no known objects or phenomena that can travel at superluminal average speed. However, some theories suggest that certain particles, such as tachyons, may have the ability to travel faster than the speed of light. However, these theories are still highly debated and not widely accepted in the scientific community.

4. How does superluminal average speed relate to time travel?

Superluminal average speed and time travel are closely related concepts, as both involve the idea of surpassing the speed of light. Some theories suggest that if superluminal average speed were possible, it could potentially lead to time travel by breaking the time-space continuum. However, this is still a highly theoretical and speculative concept.

5. What are the potential implications of achieving superluminal average speed?

If superluminal average speed were possible, it would greatly challenge our current understanding of the laws of physics and could potentially lead to groundbreaking discoveries and advancements in technology. However, it is important to note that this is currently only a theoretical concept and there is no evidence to suggest that it is achievable.
