Rainwater harvesting

I did get the rain water harvesting done. Will post more details later. But, here is the info.

1. The guys who did it for me (Susthira, Kannur) was a total rip off
2. For 12000, they only made a tank close to well and have a pipe into the well
3. They also filled filtering material
4. The tank was about 300 liters
5. The whole thing should not have cost more than 5000-6000
6. For connecting it to my already existing water draining pipes from terrace, they took another 3000

I repent not having getting it done by the Thrissur guys. On a hint sight...
1. The Susthira stuff is Ferro cement
2. Its lid is heavy and cannot be lifted easily. => Difficult to clean and maintain
3. They did not use a cloth to do initial filtering => All that solid waste gets into filtering media and makes your filtering media cleaning a mandatory task
4. The tank is fixed and it is right next to well => Cannot extend this easily to connect to a rainwater storage tank
5. The lid does not fit well. There is good enough space to let in a small rat :(
6. Its a one size fit all solution

So, though the thrissur guy's stuff was requiring me to source a few things myself, that would have given me a better system, options to customize and cleaner filtration tank.

The milky way

Just a random thought. I was reading a headline about a galaxy that was 300 light years away. Did not read the details. But, I felt that 300 light years is a a bot short distance when it comes to galaxies. So, I checked the size of milky way and found it to be 100, 000 light years in dia. There are galaxies that are 980, 000 (M87) light years in dia and another one at 1.5 million light years (Hercules A) in dia.

But, how can it be? I dont claim to be good at Physics. But something tells me that there should be a simpler and closer path connecting most of the universe.

It was just yesterday that I was seeing a video where I heard that we really do not know what happened from 0 to 10^-43 sec of big bang. Well, so, there was no physics (at least as we know it today) during that time. So, matter could travel at speeds exceeding that of light in that duration. But, did matter travel that much distance in less than 10^-43 sec? Or, was matter always present at those points where it is currently present (or at least close to it)? What was really the speed of matter just after 10^-43 sec?

May be physics has answers. I need to read further :)
