Origin of the Universe
| Question | Answer |
|---|---|
| Religion and mythology have for long time proposed that theworld came into existence out of nothing. Generally, all stories of creation emphasize the power of a Creator, Deity or God. | Divine Creation Theory |
| the Solar System formed: Hydrogen and other gases swirled around and condensed into our sun and its planets. | The Nebular Theory |
| the universe began about 15 billion years ago, in a huge explosion. This theory proposes that the universe started as a big ball of pure energy , matter, forces of nature and space were all wrapped up. | Big Bang Theory |
| Big Bang Theory was first developed in 1927 by: | Georges Lemaitre(1924-1966) |
| Big Bang Theory was coined and revised by: | George Gamow(1904-1968) |
| Alternatively, the galaxies may come together, until finally they will collide and explode. This event is called the: | Big Crunch Theory |
| believed that the galaxies of the universe are moving farther apart. This means that the universe is getting continually bigger or getting biggerforever. | Edwin Hubble |
| Proposed by Hermann Bondi, Thomas Gold, and Fred Hoyle in 1928, this suggests that the universe is infinite in time with the same condition before and now, and it has a constant mean density. | Steady State |
| defined as the totality of everything that exists, including all physical matter and energy, ranging from the smallest atom to the biggest galaxy- the planets, stars, everything. | universe |
| Made of eight planets: Mercury, Venus, our Earth, Mars, Jupiter, Saturn, Neptune and Uranus. Revolve around the Sun | SOLAR SYSTEM |
| Giant balls of hot gas, mostly hydrogen, with some helium and small amounts of other elements. | STARS |
| -The brilliant point of light is the explosion of a star that has reached the end of its life. | Supernovae! |
| believed to be a supermassive black hole surrounded by an accretion disk. Seen in the center of some galaxies | QUASAR? |
| consist of stars, planets, and vast clouds of gas and dust | GALAXIES! |
| is an interstellar cloud of dust, hydrogen, helium and other ionized gases. | NEBULA!! |
| because they emit their own light. How do they emit their own light? They glow red or pink as they expel extra energy which they get from nearby stars. | Emission Nebulae, |
| This is because rather than emitting their own light, they are reflecting the light of the stars around them. They are blue because they reflect the light of a star. | Reflection nebula |
| are interstellar clouds that contain a very high concentration of dust. This allows them to scatter and absorb all incident optical light, making them completely opaque at visible wavelengths. | Dark nebulae |
| It is an observatory that carried a telescope and traveled in space in April 1990. | Hubble Space telescope |
| It is a device for collecting radio signals from objects which are too far away to be seen by optical telescopes. | Radio telescope |
| Is a kind of radio telescope that allows radio astronomers to pick up very weak signals from space. | Radio interferometer |
| Is used to get information about stars, galaxies and nebulae. Used for breaking down light into a spectrum | Spectroscope |
| Was launched into space in 1981, It is a space truck taking astronauts cargo and equipments into space and returning facilities and equipment to Earth | NASA Space Shuttle |
| It is a shape like an aircraft and carries the crew to and from space. | Space Shuttle Orbiter |
| has been used immense distances into space, to reveal galaxies and other luminous objects. | Hale Telescope |
