Canadian bedrock more than 4 billion years old may be the oldest known section of the Earth's early crust.
Scientists at the Carnegie Institution of Washington and McGill University in Montreal used geochemical methods to obtain an age of 4.28 billion years for samples of the rock, making it 250 million years more ancient than any previously discovered rocks.
The findings, which offer scientists clues to earliest stages of our planet's evolution, are published in this week's issue of the journal Science.

There is not a true resolution by the end of Hamlet . Hamlet's main conflict is internal because he cannot make decisions. There are three big conflicts: his nation is under attack; his family is undergoing a crisis and he feels really unhappy. Therefore, Hamlet does not know if we have to act upon our fate or if we have to act out of free will: Are we responsible for our fate or our fate is conditioned by free will? This conflict is not solved. Hamlet's attitude in the final scence is different from the previous scenes since he does not want to take revenge against his father's murderer, Claudius, and he feels sorry for Laertes. Hamlet killed Laertes' father and now he would like to make peace with him. In spite of these decisions, Hamlet still feels unhappy. Hamlet has not been able to resolve the conflict between thought and action. He is still unhappy and has got a lot of doubt. This is the reason why everything goes wrong and tragic by the end of the play. Although Hamlet wants to make peace with Laertes, they get into a "fight" and Hamlet kills Laertes with his poisoned sword. Laertes' sword is poisoned because Claudius and he plotted against Hamlet.

By accident, Laertes is killed and Gertrude drinks the poisoned cup. Hamlet gets really desperate and he finally kills Claudius with the poisoned sword .
