What is dark matter ? How is normal matter different from it ? Is normal matter a converted form of dark matter ? Does universe consists of more dark matter ? Are these a result of radioactive decay or something else ? Can we study dark matter in same depth as we can for normal matter ? Is it formed by conversion of any energy into mass or vice versa ? Which matter do other planets have ? Then sun is made from which matter ? Is dark matter near around us as we say for normal matter ? How to determine these concerns ? Are several undiscovered galaxies are made up of dark matter ? Then can any form of water be formed by dark matter ? ?Does radioactivity takes place here ? Which rule in physics predicts the time in which any nucleus will decay ?What is dark energy ? Is it related here anyhow ?Is universe expanding continuously?Can we apply newton's laws of motion or heisenberg's uncertainty principle in such cases ?Are we able to see lots of elements due to these kinds of phenomenon like radioactivity ? Then undiscovered elements must be there ?After such activities , can any element get vanish or can any new element come into existence made up of just dark matter ? And also involved in nuclear reactions? Are black holes found in such places ? Is there any involvement of it ? Are black holes even bigger than stars and sun ?Is anti matter a related term here ? Is dark matter anti matter of normal matter ? No links
Dear Student,
According to standard physics, stars at the edges of a spinning, spiral galaxy should travel much slower than those near the galactic center, where a galaxy's visible matter is concentrated. But observations show that stars orbit at more or less the same speed regardless of where they are in the galactic disk. This confusing result makes sense if one assumes that the boundary stars are feeling the gravitational effects of an unseen mass which is known as dark matter.
You will learn them about in higher grades. Also requesting you to ask different question in different posts.
As we have encountered that the questions asked by you here are all from out of your syllabus. Requesting you to kindly ask questions which belong from your syllabus and subject.
Regards
