Can you see the flag on the Moon with a telescope?
The answer is basically "not a chance". No Earthbound telescope can see the flag on the Moon. Why not?

Better drainage of brain debris improves Alzheimer's disease therapies
In most of the organs of our body, the lymphatic system is responsible for conducting lymph between different parts of the body. The lymphatic system processes an average of 3 liters of lymph per day. Lymph lies between the blood vessels and the cells. The lymphatic system provides a return route to the blood vessels…
