Question from a non-physicist

In summary, light from distant stars can be bent due to the curvature of space caused by the gravity of massive objects. This could potentially result in a cumulative effect where some objects we see as light are actually dopplegangers of nearer objects, with their light bouncing around through a daisy-chain of massive objects. However, this is difficult to observe or document, as the intensity of these dopplegangers would be very small. Additionally, there are other effects such as Einstein crosses and gravity lensing that can also result in double images of stars.

Regarding the concept of light from distant stars "bending" due to the curvature of space caused by the gravity of massive objects:

Question: can there be a cumulative effect? Could some of the objects we see as light actually be dopplegangers of nearer objects, their light carroming around space riding a daisy-chain of massive objects? Is this even possible?

Theoretically, yes. In practice, I believe that this is difficult to observe or document - the intensity of these dopelgangers would be miniscule.

You can get things like einstein crosses and other sorts of gravity lens effects that lead to double images of stars.
 

1. What is physics?

Physics is the branch of science that studies the interactions and behavior of matter and energy in the universe. It seeks to understand the fundamental principles and laws that govern the natural world.

2. Why is physics important?

Physics is important because it helps us understand the world around us and how it works. It has practical applications in many fields such as engineering, medicine, and technology. It also allows us to make predictions and develop new technologies that improve our lives.

3. What are some common misconceptions about physics?

Some common misconceptions about physics include the belief that it is only relevant to highly complex or technical topics, or that it is all about memorizing equations and formulas. In reality, physics is applicable to everyday phenomena and is more about understanding concepts and principles rather than just memorization.

4. Can non-physicists understand physics?

Yes, anyone can understand the basic concepts and principles of physics. While the mathematics involved may be challenging, the fundamental ideas can be explained in simpler terms. It just takes some effort and curiosity to learn and understand.

5. How can I learn more about physics as a non-physicist?

There are many resources available for non-physicists to learn more about physics. You can start with popular science books or documentaries that explain physics concepts in an accessible way. There are also online courses and tutorials that cater to beginners. It's important to stay curious and keep asking questions!
