Chapter II Light and Matter The Inner Workings of the Cosmos 2.4 The Distribution of Radiation All microscopic objects – fires‚ cubes‚ people‚ and stars – emit radiation at all times. They radiate because the microscopic charged particles in them are in constant random motion‚ and whenever charges change their state of motion‚ electromagnetic radiation is emitted. The temperature of an object is a direct measure of the amount of microscopic motion within it. The hotter the object

There is much more dark matter than normal (visible) matter in the universe. According to (this source) roughly 68% of the universe is dark energy. Dark matter makes up about 27%‚ while everything else in the universe (physical matter like the atoms that make up planets and stars) makes up less than 5% of the universe. According to (this source) the universe is actually 96% of dark matter and dark energy. With 73% being dark energy and 23% being dark matter but the implications of this much

“IT IS NOT WHAT YOU LOOK AT THAT MATTERS‚ BUT WHAT YOU SEE” - H.D. THOREAU To look is to see and vice-versa! Admittedly to a layman and also in common parlance‚ we use the two interchangeably or synonymously.

To look at something and to actually realise your vision is not always possible. There is just too much‚ all around

Analysis Questions: Cycles of Matter 1. Explain the role of decomposing bacteria in the carbon and nitrogen cycles. In the carbon cycle‚ decomposing bacteria release carbon from the decaying bodies or waste into the atmosphere. Without them‚ it won’t be able for any organism to access the carbon stored in dead bodies. In the nitrogen cycle‚ decomposing bacteria breaks down animal waste‚ which creates ammonia and nitrate products rich in nitrogen. Although no animals or plants cannot directly

Dark Matter Astronomy Samuel Research Topic Topic: Dark Matter‚ Astronomy Saul Perl mutter‚ 2011 states “The Universe in made mostly of dark matter and dark energy‚ and we don’t know what either of them is.” The above statement by Saul Perl mutter suggests that astronomers at this age have found this unknown substance by the name of Dark Matter. We chose this topic on Dark Matter as it intrigues us what is beyond our atmosphere and what is it made off. We want to know how Scientists realized

The Nature of Dark Matter We observe the universe around us through many scientific means. However it is through the electromagnetic spectrum‚ that is everything from radio waves to gamma waves‚ that we learn about the objects in our world and beyond. However we can also learn about our universe through indirect means‚ such as the effect of gravity on light as well as larger objects like our galaxy. In fact it is this indirect method of observation that has led us to the discovery of extra-solar
