Perception

“Ostensibly physical objects like tables and chairs are really nothing more than collections of sensible ideas. Since no idea can exist outside a mind, it follows that tables and chairs, as well all the other furniture of the physical world, exist only insofar as they are in the mind of someone, only insofar as they are perceived. For any nonthinking being, to be is to be perceived.”
- George Berkeley

This Image shows some of the earliest galaxies in our universe. Some of them are as much as 13 billion years old. The image required 800 exposures taken over the course of 400 Hubble orbits around Earth. The total amount of exposure time was 11.3 days.
