Ways to detect extrasolar planets

Scientist can detect extra solar planets by direct evidence such as images of the planet and the planets spectrum, and by indirect evidence such as Doppler techniques and transits.

What did the universe look like before the Big Bang?

Before the big bang, i think the universe was probably a vast wasteland of nothing but large quantities of cosmic dust and other materials that would later come to serve as fuel/materials for the creation of the universe. I also think that there were forces or laws of the universe that contributed to the motion or attraction of objects in space billions of years ago.



The big bang formed because all of the matter, dust, foreign objects and elements collected into a single mass; which probably gave way to the extreme amount of weight/gravity of the huge mass; then a sudden, catastrophic explosion and sharing or splitting of matter and anti matter or nuclear reactions from atoms sent cosmic debris all over space; which later formed, cooled and created the cycles, stars, galaxies and objects that we view today.

My Favorite Science topic is...

My favorite topic, that we've went over this year was Astronomy; which is the study of the universe or space. Astronomy covers a lot of things in space, such as Black holes, Red giants, galaxies, constellations and theory's of how the universe formed or how it will end.

Astronomy is so interesting and cool to me because its vast size and gorgeous views. Astronmy is like watching still pictures or sometimes videos of 1080p HD pics on the best tv brand, flatscreens. It is truly a sight to admire.
