I know all of you are busy preparing for your terminal exams, so I am posting only videos of shorter duration. On Oct 19th 2010, astronomers announced the measurement of a redshift of 8.6 for one of the galaxies in the Ultra Deep Field. Here’s the news release from ESO’s website. This is old news but relevant to understanding the Cosmos.
The question of what caused the Big Bang is one of the most difficult facing humanity. We may never find an answer, and even if we do, we probably won’t understand it. It’s difficult to imagine an event occurring without a cause, and yet, that is precisely the prospect we are faced with when it comes to this question.
Theoretical Physicist Lawrence Krauss gives a great interview on significant discoveries in modern physics and also discusses some ideas from his book, A Universe From Nothing. Lawrence articulates his ideas very well in this video. A special shout out to the interviewer Steve Paikin who asks tremendous questions. This interview was given in 2013 in Canada and this is the first part. His book “A Universe from Nothing: Why there is something rather than nothing” is a fantastic read and I recommend it strongly for people having questions and those interested in knowing about the origin of the Universe.
Dr.Brian Cox is a popular Physicist who makes science interesting for young people. In this video he is speaking to the students and teachers of schools in the UK about the universe. Please see the video patiently till the end. We have discussed much of it in our meetings earlier but hearing from Prof. Cox is different. If you have any doubts note them down and I will clear them the next time we meet or you may leave a comment and I will try to clarify where ever possible.
