Unless the mirror is already there, getting it set up will require so much time that you'll not see any farther into the past than when you launched it.atarah said:
Your bathroom mirror will give you a delay of ten nanoseconds or so. that would be a start!atarah said:
The concept of "Space, Reflection: See Earth's Past in Mirror" refers to the idea that when we observe distant objects in space, we are essentially looking back in time. This is because light takes time to travel through space, so the light we see from distant objects has been traveling for thousands or even millions of years, giving us a glimpse into the past.
The farthest we can see back in time with this concept is approximately 13.8 billion years, which is the estimated age of the universe. This is because the light from the most distant objects in the universe has been traveling for that amount of time to reach us.
This concept helps us understand the history of Earth by allowing us to observe distant objects in space that are actually images of how those objects looked in the past. By studying these images, we can gain insights into the formation and evolution of our own planet and the universe as a whole.
No, we cannot use this concept to see events that happened on Earth in the past. This is because the light from Earth's past events has already reached us and is no longer traveling through space. However, we can use other methods such as studying geological and fossil records to learn about Earth's past.
Yes, there are limitations to this concept. One limitation is that the farther we look into space, the more distorted the images become due to the expansion of the universe. Additionally, some objects may be too far away for their light to ever reach us, meaning we will never be able to see their past. Another limitation is that we can only see as far back in time as the existence of the universe itself, so we cannot see anything that may have happened before the Big Bang.
