Relativistic Journey From Earth | Accelerating at 1g to a Distant Star

Q2OoU6Ao3QIn summary, the conversation is about finding a video that explains the visual effects of a relativistic journey from Earth to a distant star, including length contraction and color distortion. The conversation also briefly mentions the ability to still see objects that have been passed by the ship from the front, and suggests using Google to find relevant videos.

Hi does anyone know where I can find a video that shows what one would see if one went on a relativistic journey from Earth, accelerating at 1g to a distant star?

I have some idea for example length contraction when looking perpendicular from the direction of travel, and things in front would become blue and things behind red; and the shapes would be distorted.

I have read that objects the ship has recently passed would still be visible from the front for some time, why does this happen?

Welcome to PF!

If you use Google you should be able to find a number of videos on the net showing relativistic effects, for instance [1].

1. What is a "Relativistic Journey From Earth"?

A relativistic journey from Earth refers to a hypothetical scenario in which a spacecraft travels at a significant fraction of the speed of light, typically in the context of interstellar travel. This journey involves accelerating at a constant rate of 1g (9.8 meters per second squared) in order to reach a distant star within a human lifetime.

2. What is the significance of accelerating at 1g?

Accelerating at 1g (9.8 meters per second squared) allows for the spacecraft to reach near-light speeds and maintain a comfortable level of artificial gravity for the passengers. This level of acceleration also allows for the journey to be completed within a reasonable amount of time, as opposed to a slower acceleration which would make the journey much longer.

3. How long would it take to reach a distant star using this method?

The duration of the journey would depend on the distance to the chosen star and the rate of acceleration. However, with a constant acceleration of 1g, it would take approximately 1 year to reach a distance of 1 light year, 2 years to reach 2 light years, and so on.

4. What are some challenges of a relativistic journey from Earth?

There are several challenges associated with a relativistic journey from Earth. One major challenge is the amount of energy and resources required to accelerate a spacecraft to near-light speeds. Another challenge is the impact of time dilation, which would cause the travelers to experience time differently than those on Earth. Additionally, the potential effects of high-speed collisions with interstellar particles and radiation must be taken into consideration.

5. Is a relativistic journey from Earth possible?

While there are many theoretical and technological challenges associated with a relativistic journey from Earth, it is not impossible. With advancements in propulsion technology and further understanding of the effects of relativity, it may one day be possible to embark on such a journey. However, at this time, it remains a hypothetical concept.
