ROAR. The Universe In A Nutshell by Stephen Hawking
1.
Comments
- The speed of light is through perception, due to the Doppler affect.
- A series of experiments failed to prove this theory.
- The speed of light is independent.
- The Twin Paradox states that time travel slows down time.
- Objects try to move in a straight line.
Questions
- Why does space travel near the speed of light slow down time?
- If time is slowed during space travel, near the speed of light, is it possible to somehow travel through “time” indefinitely?
- How and why do Mass and energy warp Spacetime

Comments
- Light curves due to gravity.
- A star behind the sun can be seen because of the light curves.
- The universe is expanding.
- Time becomes warped around stars
- Time ends in a black hole
Questions
- Isn’t light only able to be curved by black holes because of their high gravitational pull?
- When the universe expands to a critical point, gravity will lessen, the galaxy will stop orbiting other galaxies, what will happen then?
- If time ends in a black hole, is it possible for objects to be returned?
- Black holes are assumed to crush whatever enters by its gravitational force, however, if time stops in a black hole, would you not still be alive because your life would not end because time has stopped?
Vocabulary

Comments
- Time is eternal.
- People hypothesize that the universe was only made a couple thousands years ago.
- One may curve time, as it is not possible to be able to curve space without involving time as well.
- It is possible to curve time
- Time is theorized to be a string; it is possible to loop back however events are not possible to be changed, as no matter what a string will always be in a straight line, like time.
Questions
- Is it possible for time to “loop” back?
- If the universe had been created, why had there been an infinite wait before its creation?
- If the has existed forever, why hasn’t everything to happen already happened, meaning history is over?
- If time is forever, that would mean that the universe has been around forever, if it has been around forever, why hasn’t the universe reached equilibrium?

4.
Comments
- It is said that space is like a rubber sheet
- The theory of relativity PREDICTS the universe
- When one look out into space, one sees back in time.
- People theorize that the universe is closing up; this is because as we look into space, the galaxies are spreading, but as you may remember, we are seeing into the past, meaning the universe may be closing.
- There is an uncertainty principle; this principle says that particles are always in constant movement, meaning it is impossible to predict its movements and location.
Questions
- How many dimensions are a part of the universe?
- If there are more than 4 dimensions, what do the other dimensions measure?
- How is mass equal to energy?
- Are all p-branes created equal?
Vocabulary
- Fluctuations: continual change from 1 point or condition to another
- M-Theory: string theory, web of dualities.
- Imaginary Time: Time moving alongside real-time that scientists refer to
Literary Terms
- Analogy: space to rubber sheet.
Overview Sentence
- To be honest, I am still unclear how to explain this section of the book, as it is very confusing and complicated, but it tells of M-Theory, a new, complicated theory, and it theorizes in space and time and quantum theory.

5.
Comments
- Black holes are a collapsed star
- Black holes stop time (inside)
- It is said that black holes have a massive amount of gravity that supposedly creates holograms.
- There is a deep connection between quantum gravity and thermo dynamics
- If time is stopped within a black hole, is it possible to send a capsule that can withstand the gravitational force, and allow the capsule
Questions
- Is it possible to recreate what has entered the black hole if it can project holograms?
- Is the universe actually infinite or very large?
- Is the universe ever-lasting or just long lived?
- Are wormholes existent?
Vocabulary
- Entropy: a function of thermodynamic variables, as temperature, pressure, or composition that is a measure of the energy that is not available for work during a thermodynamic process. A closed system evolves toward a state of maximum entropy.
- Consistent: constant
- Frontier: border
Literary Terms
- No literary terms found for this section.
Overview Sentence
- This chapter is all about black holes, their functions, theories, and other things scientists have said about them.

6.
Comments
- No one really knows where the end of the universe is.
- The universe must have a beginning, and yet it is forever
- Inflation of the universe could harbor more intelligent life.
- M-Theory consists off over 10 dimensions.
- Real time history continues to spiral off larger and larger while imaginary time spirals in a ball.
Questions
- What is the end of the universe like?
- Is the frontier of space a point in space?
- Is the frontier of the universe a jagged point where space and time were scrunched together, with an infinite density?
- Does the universe have a beginning?
Vocabulary
- Inflation: inflation
- Fluctuate: vary
- Vacuum: void
Literary Terms
No literary terms found for this section.
Overview Sentence
- This section talks about the expansion of the universe.

7.
Comments
- Universe has 3 regions, supernovae, clustering, and microwave background.
- All of these regions have a common intersection
- If there is matter in the region, it means that the universe ha sped up its expansion rate
- Imaginary time is a tiny flattened sphere
- Imaginary time resembles a nut
Questions
- Why do scientists refer to imaginary time?
- Is imaginary time a hypothesis or a theory?
- Is it possible to predict the future?

8.
Comments
- It is possible to predict the future.
- If you know where and at what speed something is moving, you can predict where it well be (future)
- A great controversy is the butterfly effect. The butterfly effect says that if one were to go back in time and change something, something else would change in the present. Some scientists believe time is like a string where nothing can be changed. Others believe that the butterfly effect is plausible.
- It is said that if u input lousy variables and coordinates, then you would get lousy answers, meaning prediction of the future is very precise.
- Wormholes may lead to time travel.
Questions
- Is there a formula or formulae that allows one to accurately predict he future?
- Are wormholes discrepancies in the universe or are they meant to be there to allow easier travel?
- Every percepts spacetime differently, is it possible for people to travel through time at different rates?
- If gravity affects light and warps spacetime, is it possible for a star to be sp massive that light cannot escape its pull?
Vocabulary
- Relativity: subject to 1 person
- Quasi-stellar: a radio source (according to Hawking’s book)
Literary questions
No literary terms found in this section. Clearly Hawking does not use them often, or perhaps, I do not notice them.
Overview sentence
- This section of the book talks about space travel and the possibility of predicting the future and also time travel.

Comments
- Space stops in a black hole
- A black hole records all information that has been sent into it
- Scientists theorize that it is possible to extract the information from the black hole when it dissipates, but it said that the information disappears into an alternate dimension(how sci-fi -.-“)
- An astronaut, who is drawn into a black hole, will never be heard from again, because the radio signals he/she is broadcasting would get sucked into the black hole.
- Virtual particles appear and annihilate each other close to the black hole’s horizon

- Time travel… however ludicrous, is possible.
- Time travel is possible through machines that an advanced civilization coming back
- However, time travel is also possible through the warps and contours of space and of course, through wormholes.
- It is possible for a spaceship to go through the extreme warping of space and return before the ship even takes off.
- This space warping, if exploited, could be very useful… or disastrous.
Questions
- Is it possible to create a machine which warped the surround space and time to the point of time travel?
- How accurate is the butterfly effect in describing time effects?
- How accurate is the string theory of time in describing the effect s of time?

- Warp: distortion
- Contour: curve
- Butterfly effect: the theory that if one goes back in time and changes something, something in the present would change.
