Suppose light (charged with images from earth) is beamed to a reflective focus in space at say 50 light years.

Suppose in 2063 the beam strikes the reflector and bounces back to earth.

Suppose in 50 more years (2113) the reflected beam attains earth and is collected umblemished as originated in 2013.

Suppose in 2113 images originally contained in the 2013 beam
can be viewed.

Then in 2113, citizens of earth, would be able to view images 100 years old of the site earth.

Suppose all the above is technically feasible on a continuous basis and stored.

Then earth people can achieve the most wonderful archive ever thought of.

Seems to me SETI with their millions should give some attention to this.

Any views?
