Identifying Gravitational Theories
Name a gravitational theory.
Acceptable answers: name one of them
1. extra dimensions
2. distortion of space-time/general relativity
3. (regulated) by quantum gravitons
Gravity works only to _____ objects and not to _____ them.
Pull/attract, push
True or False: The Standard Model is super effective as describing a convenient amount of the natural world.
True
Which famous scientist is credited with founding and formulating the Theory of General Relativity?
Albert Einstein
What is the most widely accepted gravitational theory?
Theory of General Relativity
What are the two certain peculiar properties that gravity possesses that makes it special in comparison to other forces?
It's really weak and it only attracts/pulls; it doesn't push
(Bonus: It doesn't cancel itself out since it doesn't have negative charges)
True or False: The weak force has a short range because its force particles barely have any mass which limits how far they travel.
False: The force has a short range because its force particles have a lot of mass which limits how far they travel.
What occurs when a gravitational wave passes by an object?
It stretches and distorts it.
The Theory of General Relativity reasons that gravity is a ____________ of space. (hint: word has 3 syllables)
distortion
What is the name of the general model that is recognized by quantum physicists to depict the forces of the natural world but not gravity?
The Standard Model (of Quantum Physics)
According to the book, how weak is gravity compared to other forces?
About 1036 times weaker
What is the universal unit utilized to describe forces in quantum physics? (hint: begins with letter "p")
particle
What ripple-like entity does an accelerating black hole often produce?
Gravitational waves
General relativity indicates that space is part of a dynamic, flexible operative of the universe called ______-________.
space-time
What two theories contradict each other because they disagree or whether or not it is possible to isolate anything to its smallest, singular point?
Theory of General Relativity and Theory of Quantum Mechanics
What two reasons make gravity so prominent in our universe? (Why do most objects succumb to its power and stay rooted to the ground)
1. Its force is proportional (multiplies) based on the mass of the object
2. It only has a positive charge so it remains active/effective while other objects with both negative and positive charges cancel each other out
What is the name scientists have dubbed for the hypothetical particle that would transfer gravity?
Graviton
By measuring gravitational waves and their inteference with the bounce of lasers, LIGO was able to confirm that gravity does what to space?
Gravity bends space.
What shape does the Theory of General Relativity propose is the space around a planet and the star it goes toward and revolves around?
circle/ellipse
The Theory of Extra Dimensions introduces the ideology that gravity may be just as ______ as other dimensions.
strong
Name the 4 fundamental forces.
Electromagnetism, weak force, strong force, and gravity.
Why does the field of Quantum Mechanics fail to describe gravity? Identify one reason.
1. The Standard Model requires a particle that transmits the force of gravity which has not been discovered/visibly noticed yet.
2. Other theories of gravity such as Einstein's Theory of Relativity have been prevalent for a long time; therefore Quantum Mechanics is unnecessary.
What does LIGO stand for? (may be helpful to think about what it measures from black holes)
Laser Interferometer Gravitational-Wave Observatory
Name a specific problem, impact or question that the Theory of General Relativity has assisted explaining (other than the definition of gravity and why planets don't travel randomly)
One of the following:
-local gravity
-cosmic gravity
-why light bends around objects
-why GPSs work
-the prediction of black holes
