The article, “Our Universe could be reborn as a bouncing baby cosmos” by Lisa Grossman suggests that there may be a new theory to how the universe began, that seems to be more accurate than the current theory. This new theory created by Neil Turok and Steffen Gielen is the new Big Bounce model; not to be confused with the older big bounce-big crunch model. This model, unlike all other past contenders, has been able to begin the first steps in an accurate description to how the universe…

The Hubble Telescope is a telescope that was created in 1990. It was launched into space and is still standing. When it launched, it was the biggest telescope launched into space. With its 2.4 meter glass it uses 4 main instruments. These instruments look for ultraviolet, visible, and near infrared spectra, it is able to make objects from long distances bigger and with the 2.4 meter glass, I don’t see why not. The Hubble Telescope was indeed launched into space in 1990. However, the origin of…

Before Edwin Hubble discovered that galaxies were receding from each other, people strongly believed that the universe was static and there was no component in it which exerted a negative pressure and countered the attractive force of gravity. This belief was so strong, in fact, that even Einstein, upon finding that his equations were predicting an expanding universe, arbitrarily added a cosmological constant to keep the universe static. A few years after GR was published, however, Hubble found…

The Hot bang and the Ageless Universe are two different theories that explain the existence of the universe. No one can prove that both these theories are real because we do not have real evidence to back it up. We do not have a strong idea on how the universe came to be because we did not exist to actually see it but when it comes to the steady-state theory, the facts are more understandable than the proof behind the Hot bang theory. I believe the most supportable theory is the Ageless Universe…

Introduction Significant advancements in technology have assisted scientists to have a deeper and more accurate understanding of the universe and it’s beginning. Over centuries the dedication and commitment to research in technology has had a major impact on discovering and understanding the universe. Such technologies include Hubble Space Telescope, COBE and the Planck satellite. Astronomers and Scientists currently estimate that the Big Bang occurred just under 14 billion years ago.Without…

Does the Steady State Theory or the Big Bang explain the origin of the universe? There are many theories that contribute to the opinions and ideas of how the universe came about approximately 13.7 billion years ago. Two highly debated theories of evolution include the ‘Big Bang Theory’ and the ‘Steady State Theory’, two of which have very different points of view about how the universe came to how it is today. The ‘Big Bang Theory’ discusses how the universe began as a very small, hot and dense…

to learn in general, nobody really knows anything for sure when it comes to the universe. Overall what I have learned the most this semester include the concepts of redshift, the fact that the universe is expanding, how huge the universe is, and that the Big Bang theory is not as ridiculous as I previously believed it to be. Redshift describes how light changes as objects in space) move closer or farther away from us. Because on the light spectrum when things are moving away…

3. Tasks In order to get answers to the Mission questions, Euclid will measure the geometry , expansion rate and structure growth in the Universe as a function of redshift. This map, spanning 3/4 of the lifetime of the Universe will complement the single snapshot at z ≈1100 made by WMAP and Planck. By combining the use of Redshift measurements (4.1), Weak gravitational lensing (4.2) and Baryonic Acoustic Oscillations (4.3), both Dark Energy (DE) and Dark Matter(DM) will be investigated in the…

altered by the peculiar motions of the very galaxies in which he was observing. To get more accurate and better results, the galaxies used should have a distance much greater so that the cosmological redshift that is caused by the expansion of space is much more substantial than the Doppler redshift ascribed to the the induvial galaxies peculiar motions though the…

telescope that he created and it is called the hubble telescope. When the universe exploded it began to spread really quickly and when it exploded the universe had a very high temperature when this happened. Which created formation of elements ,gravity,redshift ,doppler effect,CMB, many more . The big bang theory expanded in a trillion of a second when it exploded with a bunch of light rays came shooting out with brightness. The galaxies were formed by hydrogen and helium which began to help…
