There are many reasons to expect some sort of quantum structure of space-time at very short distances, notably at the Planck scale. We will discuss a possible mathematical realization of such ...

... How much more light gathering power does a 10m telescope have than an 0.5 m telescope? Answer: The light gathering power is proportional to the square of the mirror’s diameter. (10m)2/(0.5m)2 = 100m / 0.25m = 400 So you can see objects about 400 times fainter with the 10m telescope in the same amou ...
