Could something be seen going the speed of light?

Click For Summary

Discussion Overview

The discussion revolves around the question of whether something moving at the speed of light can be seen, particularly focusing on the interaction of light rays with such an object. The scope includes conceptual reasoning and exploratory ideas related to light, visibility, and detection methods.

Discussion Character

  • Exploratory
  • Conceptual clarification

Main Points Raised

  • One participant questions if something could be seen moving at the speed of light, suggesting that light rays reflected off the object could make it visible.
  • Another participant agrees that light travels at the speed of light and is visible, but notes that the visibility of an object moving at light speed depends on the type of massless particle and suggests using matter for detection.
  • A participant clarifies their question, indicating they meant an asteroid moving at light speed could be seen if it interacts with light rays.
  • Another participant responds that detection does not necessarily require light; an object could collide with matter, which would then emit light that could be observed.

Areas of Agreement / Disagreement

Participants express differing views on the visibility of objects moving at light speed, with some suggesting the use of light for detection and others proposing alternative methods. The discussion remains unresolved regarding the feasibility of seeing such objects.

Contextual Notes

Assumptions about the nature of light and massless particles are present, and the discussion does not resolve the implications of these assumptions on visibility.

Could something be seen going the speed of light? Shouldnt we be able to see it if the "light rays" reflected off of it (assuming it is not on a vector away from the sun, and not parallel to the beams of light being emmited from the sun)?

Sure, light goes at the speed of light and we see it all the time. :smile:

Depends on the kind of massless particle. Light can reflect other light, but only very weakly. You're better off using matter to "see" it.

Good point! I think I didnt word the second part of my question very well, I meant that you would be able to see something such as an asteroid going the speed of light as long as it ran into light rays.

I know what you meant, but what I'm trying to say is that you don't need to use light to detect something moving at light speed. You can have it run into matter, which will then emit light that you can see with your eyes (or some other instrument).
 
OOOH! I see. Thanks!:smile:
