Stellary Starry Universe

 

Speaking about his new book “Physics of the Impossible,” Dr. Kaku explains with how Physics one day may allow us to go back in time. Humorous, enlightening, and thought provoking. One wonders if there really is such a thing as parallel universes and multiple realities. You see it all the time in movies and on TV, but are there really such realities?

 

We can’t see dark matter, and some skeptics doubt its existence, but many scientists think it makes up 20-some percent of our universe. Astronomer Doug Clowe explains how the Bullet Cluster, a group of galaxies billions of light years away, may shed some light on this mysterious stuff.

 

This video covers the 93 million mile journey that a neutrino takes from the center of the Sun to the Earth, and how we detect them. Our initial attempts to detect them were ineffective. There were way too few neutrinos, causing scientists much concern. However later things were made right when it was determined that there were three kinds of neutrinos and our detectors only detected one kind, the electron neutrino.

In addition to the electron neutrino there is a meuon neutrino and a tauon neutrino. These almost massless super fast particles normally zip right through the earth direct from the heart of the sun. It is very difficult to detect them since they pass through all matter easily.

The Solar System’s birth was far from peaceful. Witness the spectacular explosion known as the “Big Bang” which happened billions of years before. Although the solar system looks peaceful its birth was anything but peaceful.

Here is a short video about the birth of the solar system.
