- 3. Matter Is the matter that makes up all observable tangible objects that account for 5% of the universe.
- 5. Astronomical conclusions based on observations and years of research.
- 6. An invisible force that acts between all objects pulling them together in accordance to distance and mass.
- 7. The process of detecting and identifying celestial objects typically with the use of sensors and telescopes.
- 11. The system’s capacity to do work, such as nuclear fission, illuminating, and heating up.
- 15. The ebb and flow of the tides, the solar system’s orbit, and light bending due to dark matter is all examples of:
- 16. As the universe expands it is slowly increasing in speed, this is called the:
- 19. Unknown and unexplained phenomena of the universe.
- 21. The outcome the universe if the dark energy increases its power over time causing the expansions to accelerate so rapidly that cosmos and atoms themselves rip apart
- 22. The outcome for a closed model of the universe where gravity dominates the rate of expansion, causing a rapid collapse of the universe back into itself.
- 23. When a celestial body is in an opposite position from the sun.
Down
- 1. A mysterious form of energy that forms 68% of the universe. It has a ‘repulsive’ prosperity that helps accelerate the expansion of the universe.
- 2. A gravitationally bound system consisting of star, cosmic dust, interstellar gas, planets, and dark matter.
- 4. A totality of space, time, matter, and energy as a result of the Big Bang.
- 8. The continued growth of the universe outwards, this is called:
- 9. The outcome for an open model of the universe where the gravity is less than the rate of expansion, causing the universe to expand indefinitely until it runs out of fuel for new star formation causing heat death.
- 10. An unseen matter that does not interact with the electromagnetic spectrum, and thus has to be detected through gravitational activities. It makes 85% of the universe and is the ‘glue’ that holds the universe together.
- 12. The process of introspecting celestial objects and the physics, chemistry, mathematics that make them work.
- 13. Any physical substance that has mass and volume.
- 14. The physical universe and all its celestial objects. It can also be used as a term to describe the deposition and characteristics of celestial objects.
- 17. The entire physical universe viewed as a complex harmonic system with an orderly structure that incorporates space, time, and physical laws.
- 18. 95% of the universe’s makeup that cannot be visually observed directly but must instead be detected through other means such as gravity. This includes dark matter and dark energy, both of which are considered:
- 20. Being stationary, in astronomy this can refer to a model of the universe where space is neither expanding nor retracting, remaining the same.
