Abstract
Some implications and consequences of the expansion of the universe are examined. In Chapter 1 it is shown that this expansion creates grave difficulties for the Hoyle-Narlikar theory of gravitation. Chapter 2 deals with perturbations of an expanding homogeneous and isotropic universe. The conclusion is reached that galaxies cannot be formed as a result of the growth of perturbations that were initially small. The propogation and absorption of gravitational radiation is also investigated in this approximation. In Chapter 3 gravitational radiation in an expanding universe is examined by a method of asymptotic expansions. The 'peeling off' behaviour and the asymptotic group are derived. Chapter 4 deals with the occurrence of singularities in cosmological models. It is shown that a singularity is inevitable provided that certain very general conditions are satisfied.

How do I use lucky patcher without rooting the phone?

Image
Someone requested me to describe the whole process.Here is how we do it. 1. First download  Lucky Patcher. 2.Install it in your phone. 3.Open the app.you will see something like this. 4.Click on the app you want to modify.Like i selected hill climb racing 5.Click on "Open menu of patches" 6.Now click on "create modified apk" 7.If custom patch is available click on it.If not click on"Apk rebuilded for InApp and LVL emulation".Here I am clicking on "Apk rebuilded for InApp and LVL emulation". 8.Click on "Rebuild The App" & wait some time 9.If it shows patch pattern success.Then there are chances if it shows all failed means there are no chances of you cracking the app.Here we got patch pattern success. 10.Click on Go to file. 11.Click on the file.Select Uninstall & install 12.It  will ask you to uninstall the installed app.Go on uninstall the app.After unistalling cancel it.

A list of phobias.....

Image
We define a phobia as ‘an extreme or irrational fear of or aversion to something’. You are probably aware of the more common phobias, such as  arachnophobia  (fear of spiders),  claustrophobia  (fear of enclosed spaces), and  agoraphobia  (fear of open places), but did you know there are also words which describe the fear of  idleness ,  worms , and even  body odour ? Explore the list of phobias below to discover the terms for some of the more interesting fears you may encounter. Although if you suffer from  logophobia  (a fear of words), it’s probably best to step away from this blog now… in fact, this list of phobias may be your worst nightmare!

How do Scientists Read Chromosomes?

Image
To "read" a set of chromosomes, scientists use three key features to identify their similarities and differences: Size.  This is the easiest way to tell chromosomes apart. Banding pattern.  The size and location of Giemsa bands make each chromosome unique. Centromere position.  Centromeres appear as a constriction. They have a role in the separation of chromosomes into daughter cells during cell division (mitosis and meiosis). Using these key features, scientists can identify all 46 chromosomes — one set of 23 from each parent What are centromeres for? Centromeres are required for chromosome separation during cell division. The centromeres are attachement points for microtubules, which are protein fibers that pull duplicate chromosomes toward opposite ends of the cell before it divides. This separation ensures that each daughter cell will have a full set of chromosomes. Each chromosome has only one centromere. During cell division, microtubule
