The Most Distant Galaxy Ever Measured

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.

What Caused the Big Bang?

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.

27th August- The false information being spread on social media

Today one of our staff at school  came up to me and asked me about the 27th of August when there will be two full moons in the sky. He had got this information circulating on ‘whatsapp’ . The rumour has it that one of the planets  viz., Mars  will appear as big as the moon and as if it were another moon.  First of all for those of you who have taken this news seriously  please note there is going to be only a thin crescent moon in the sky on that night. This is a Hoax –Do not Believe this news and waste your time on the 27th. Mars can never ever appear as large as a full moon as seen from Earth. The moon is much closer than Mars which appears like a red starlike point and is much further away from Earth.

Interview with Lawrence Krauss

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.
