### Wild cat

It was around 15-20 years back. An unknown wild cat from my village used to hunt the chickens. People call this cat as bavuru billi (or pilli). Unfortunately I have never seen this cat. Last time when I went to my village I got some information about this cat. This cat still exits in my village. This cat hunts only in night , it is very difficult to spot in day time. This cat is bigger than usual domesticated cat. my village is in coastal area in Andra pradhesh. If somebody I have any information about this cat please send me details. I am just trying to find out which cat species it is.

### Relative time-machine

This relative time machine is not for time traveling, for different purpose. Let’s think relative time-machine is a specialized cabin, the person inside cabin can change the time flow rate relative to out side time flow rate. If he decreases the relative time-flow rate lets say by ¼, which means that time-flow rate is one quarter relative to out side time-flow rate. If he spends an hour and came out, he spends only one hour when he suppose to spend 4 hours. This case he is 4 hour younger relative to his actual age. Similarly if he increases time flow rate by 4 now he becomes four hours older than his relative age.

I will give one interesting example for this.

Let’s imagine a scenario a person is preparing for his academic examinations. He has only 1-hours left for exam to start, but he is not confident and he didn’t prepare well. If he writes the exam he will sure fail. He needs at least 4 days to prepare. If he fails he needs to wait for another year to write the exam. Now he sits in the cabin and decreases the relative time-flow rate by 1/96 that means 1hours equal to relatively 4 days. Now he has enough time to prepare for his examinations. In this case he saves approximately 1year by using his future 4days. But he becomes 4 days older to his actual age. That means he saved 365-4 = 361 days.

Same logic can be extended to space. I will talk about this later.

According to special relativity the above scenario can be possible. But I talked about stationary cabinet. This is Einstein special relativity formula for calculating time dilation.

In this case object has to move very high speeds to get sufficient *∆t'*

### Closed Universe

I always fascinated about space science. I got interest in this area when I was in 10th Standard. That time I had a book which is translated from Russian language to Telugu.

We feel like we are living in the three dimension world (here I am not considering time as another dimension). Think that our universe is a four-dimensional sphere or ellipsoid. If this is the case our universe is closed . Anyway we cant imagine 4D space. But if our universe is a 4D sphere then there is radius that means there is limit . If there is limit we generally assume there is start point and end point. Here there is not start or end point. In this case space is curved and formed a 4d-sphere. Assume Sphere and it is very big if you are in surface it looks like a plain area but actually it is curved. Closed universe space is curved in 4D-Space.

### Kodai Biodiversity

Some time back I went for trekking in Kodaikenal. This place has different climate because of the high altitude (Around 2200 meters from sea level). There are other places also there with this altitude which includes Ooty, Munnar. Trek path is near to kodai and there the altitude is 2300 msl. This trek was through some shola forests. The plant and plant species density is very high.

Between we crossed a pine forest. This is a artificial one and planted by Britishers for wood. I hardly see any birds here. I believe these pine trees doesn't provide any food for native fauna.

I see forest department planting native trees in the cleared pine tree forests. I don't know whether they cut pine trees to plant native trees or any other purpose. Naturally grass lands with shola forest co-exists. This place has high density of flora and fauna.
