6 What planet are you come from?

7 Milky Earthway galaxy Solar system

8 What clump these object together? Earth Sun Galaxy

9 They are all clump together with Gravity

10 Gravity is important to us and it is one of the main sources to create life Without gravity planets cannot be create Without gravity stars cannot born Without gravity galaxies cannot form Without gravity life cannot evolve and we do not exist

11 Since gravity is so essential to universe, Physicist try to study it. The study of gravity lead us to

12 Black holes which we can see in movie To understand more about BH Let s move on

13 Content 1. Theory for gravity 2. Types of Black hole according to Theory 3. Indirectly observe Black hole visualize in movie 4. Interstellar Black hole

14 1.Theory for gravity

15 The most modern theory to explain gravity In present time is General Relativity Albert Einstein

16 What is GR?

17 General Relativity the effects of gravitation are ascribed to space-time curvature by mass instead of a force

18 spacetime is curved by matter, and that free-falling objects are moving along locally straight paths in curved space-time

19 What do we use to describe GR?

20 Equation to explain curve space Einstein Field Equation

21 The solutions are metric tensor describes a geometry of spacetime or in this case black hole

22 4 Notable solutions of the Einstein field equations that describe black hole include:

23 Movie use 1: Rotating Black hole no charge

24 Movie use 2: Spin very fast in order to maintain Miller s planet 1h = 7yrs Near So that speed it of doesn t light collapse e775c1428d7461e3c58fe8e159 ar_movie_blackhole.jpg.crop.originaloriginal.jpg?convert_to_webp=true

25 Now we know that black hole exist in theory And how many types could it be in theory?

26 2.Types of Black hole according to Theory

27 1. Supermassive black holes 2. Stellar black holes 3. miniature black hole E8F67849A95693C/ : background image for all slide

28 massive star run out of fuel Core collapse Explode as supernova BH form Supermassive miniature Stellar black black black holes hole holes might have Form have a mass after formed equivalent explotion in to of the billions massive early of suns universe likely star (But astronomers do not exist in the centers of most have galaxies(including Core any collapses evidence into of our own BH their existence) galaxy) have event horizons as small as the width of an atomic particle Radius atomic billion few km size

29 Supermassive black holes Stellar black holes miniature black hole Super massive Black hole

30 Movie use 3: Super massive Black hole 149,597,870,700 meters. 100 million mass of sun radius from Sun to Earth Planets can form around Spaceship can go through bdd6dc4af3f8962f9f9a0cf?convert _to_webp=true

31 Now we know that black hole have three types in theory But can we observe it? Yes, but only indirectly observe

32 3.Indirectly observe Black hole Create feature in movie

33 Can you find how many BH in this screen?

34 two example that relate to movie Interstellar The Accretion of matter Gravitational lensing

35 ACCRETION OF MATTER

36 The Accretion of matter What is Accretion of matter? Disk around BH How do it form?

37 When BH getting near matter matter falling into the gravitational well in BH matter rotate around Black hole with Conservation of angular momentum matter form a disc-like structure

38 How can we see disk?

39 As the gas get closer to Black hole It spin faster and gain frictional forces Become hotter emit vast amounts of radiation (mainly X-rays)

40 How can jet form?

41 Magnetic field from interstellar medium connect to disk the disk carry Magnetic field into center giving rise to very strong magnetic fields Magnetic field Create twin jets carry out material

42 Magnetic field Create twin jets carry out material %2C%20accretion%20disk%20and%20gamma%20ray%20jets%20of%20a%20black%20hole

43 Movie use 4: Have accretion disk Because BH rotate So that main character can easily observe (emit light)

44 Movie use 5: Jet missing Jet occur when disk has high E and emit X-ray (that can easily kill human) In order to avoid X-ray and hazard atmosphere Assume that BH already eat all matter around it (no source for jet anymore) So that matter cool down to temp. of sun s surface (human will not died by x-ray)

45 GRAVITATIONAL LENSING

46 Gravitational lensing What is Gravitational lensing? Bending of light in space

47 Gravitational lensing bending the light from the source due to curve space-time, as it travels towards the observer.

50 Movie use 6: Have gravitational lensing Because of GR

51 4.Interstellar Black hole

52 Movie Assume1to6: Gargantua Movie Assume 1:Rotating Black hole no charge Movie Assume 2: Super massive Black hole Movie Assume 3: Spin very fast in order to maintain Miller s planet Movie Assume 4: Have accretion disk Movie Assume 5: missing jet Movie Assume 6: gravitational lensing black-hole-code-leads-to-real-science /

56 Conclusion

57 Black hole in movie have a lot of fact in astrophysics Black hole give us more understanding in gravity
