What is the James Webb Telescope?
If we talk briefly about the James Webb Space Telescope, which is known as the most powerful telescope sent into space, leaving the Hubble Space Telescope behind; As a result of many years, delays, and long efforts, this telescope with a cost of 10 billion dollars was sent to space in December 2021 under the leadership of NASA and with the contributions of Europe (ESA), Canada (CSA).
If we roughly describe the purposes of this telescope, which we expect to serve giant purposes, this telescope had 2 important big purposes:
- To provide information about the old state of the universe that has not been seen by previous telescopes. Even being able to view the first stars (about 13.5 billion years ago) formed just after the Big Bang!
- Searching for traces of life on different planets!
What Has the James Webb Space Telescope Achieved?
The hugely funded Webb space telescope that was recently sent into space (December 2021) has already completed one of its missions! The images of the Webb telescope, first shared by US President Joe Biden and then by NASA, offer us the deepest (that is, the oldest) images of the universe ever taken. And this is just the beginning!
Will Time Travel Be Possible Thanks To The James Webb Space Telescope?
A cluster about 4.6 billion light-years from Earth; so in this photo we see the galaxy cluster in question about 4.6 billion years ago, because the photons reaching the sensor of the James Webb Space Telescope departed from that galaxy cluster about 4.6 billion years ago. Maybe we can’t time travel yet, but we can see the universe as it was 4.6 billion years ago.
In other words, the images reflected in the telescope are much different in the time period we are in. Because the universe is constantly changing, expanding, and galaxies are moving away from each other. Imagine that there are living beings who view our world with their own telescopes from the center where the light comes from. Even though we exist, they won’t be able to see us because our solar system was just forming 4.6 billion years ago.
