1 Not your Grandfather’s Gravity! John Ashmead

2 Not your grandfather’s gravity www.timeandquantummechanics.com Free fall thru gravity N ewton’s Action at a distance E instein’s Gravity as curvature A ccelerating expansion of universe T hermodynamic gravity O PERAs’ superluminal neutrinos

3 Not your grandfather’s gravity www.timeandquantummechanics.com Newton’s Action at a distance Three cheers for the Black Death The apple & the heavens Endless Ellipses most beautiful Jupiter’s Moons not on schedule

4 Not your grandfather’s gravity www.timeandquantummechanics.com Three cheers for the black death ✤ Kicked off the industrial revolution ✤ Built up resistance to AIDS ✤ Gave Newton time to discover gravity

5 Not your grandfather’s gravity www.timeandquantummechanics.com The Apple & the Moon Why should that apple always descend perpendicularly to the ground…Assuredly the reason is, that the Earth draws it. There must be a drawing power in matter. And the sum of the drawing power in the matter of the Earth must be in the Earth's centre…Therefore the apple draws the Earth, as well as the Earth draws the apple. Although he had been undistinguished as a Cambridge student, Newton's private studies at his home in Woolsthorpe [1665-1666] saw the development of his theories on calculus, optics and the law of gravitation optics gravitation

6 Not your grandfather’s gravity www.timeandquantummechanics.com Endless ellipses most beautiful

7 Not your grandfather’s gravity www.timeandquantummechanics.com Jupiter’s Moons 16 ½ minutes off schedule 22 Aug 1676 Ole Rømer

8 Not your grandfather’s gravity www.timeandquantummechanics.com Einstein’s gravity as curvature The ant & the apple The solar trampoline The Roman Legion explores space Riemann curvature tensor Equations of Gravity Frame Dragging Black holes, white holes, & the steady state

9 Not your grandfather’s gravity www.timeandquantummechanics.com Of ants & apples

10 Not your grandfather’s gravity www.timeandquantummechanics.com The Trampoline

11 Not your grandfather’s gravity www.timeandquantummechanics.com Spear points & curvature Julius Markus

12 Not your grandfather’s gravity www.timeandquantummechanics.com Riemann Curvature Tensor east north b start finish Julius Effect of curvature Deltius Markus

13 Not your grandfather’s gravity www.timeandquantummechanics.com Einstein’s field equation Important bit Suspicious bit

14 Not your grandfather’s gravity www.timeandquantummechanics.com Frame dragging

15 Not your grandfather’s gravity www.timeandquantummechanics.com Black holes & white holes

16 Not your grandfather’s gravity www.timeandquantummechanics.com Accelerating expansion of universe Nobel prize last week Supernovae: Ladder to the stars Expansion of the universe Accelerating expansion Dark energy

17 Not your grandfather’s gravity www.timeandquantummechanics.com October 4 th,2011 Riess, Perlmutter, & Schmidt get 2011 Nobel in physics for discovery of expansion of universe & dark energy

18 Not your grandfather’s gravity www.timeandquantummechanics.com Type Ia supernova

19 Not your grandfather’s gravity www.timeandquantummechanics.com NASA / WMAP Science Team

20 Not your grandfather’s gravity www.timeandquantummechanics.com Dark energy

21 Not your grandfather’s gravity www.timeandquantummechanics.com Thermodynamic Gravity Hawking radiation Black hole information paradox Black holes & Thermodynamics Verlinde’s Emergent Gravity Vacuum energy

22 Not your grandfather’s gravity www.timeandquantummechanics.com Hawking Radiation

23 Not your grandfather’s gravity www.timeandquantummechanics.com The black hole Information Paradox Or, where did the fish go?

24 Not your grandfather’s gravity www.timeandquantummechanics.com Thermodynamics & gravity Surface gravity ~ Temperature Area ~ entropy Mass ~ energy

25 Not your grandfather’s gravity www.timeandquantummechanics.com Verlinde’s entropic gravity For me gravity doesn’t exist,” — Verlinde

26 Not your grandfather’s gravity www.timeandquantummechanics.com Opera’s superluminal neutrinos Meaning of Mass Little Neutral ones Superluminal Neutrinos Many papers A Disputation Of Ideas Higgs Particle not seen

27 Not your grandfather’s gravity www.timeandquantummechanics.com Mass, energy, & momentum Tardyons - slower than light, massive Photons - Are light, no mass Tachyons - faster than light, imaginary mass

28 Not your grandfather’s gravity www.timeandquantummechanics.com 309 anti-hydrogen atoms trapped for > 1000s

29 Not your grandfather’s gravity www.timeandquantummechanics.com Little Neutral Ones Sudbery Neutrino Detector Neutron Decay Neutron

30 Not your grandfather’s gravity www.timeandquantummechanics.com superluminal neutrinos? Baseline of 730 kilometers, arrival too early by 60 nanoseconds: speed of neutrinos is 2.48 10 -5 c too fast

31 Not your grandfather’s gravity www.timeandquantummechanics.com 85 papers as of 10/12126 papers as of 11/18

32 Not your grandfather’s gravity www.timeandquantummechanics.com A disputation Of Ideas Forbidden by cherenkov radiation Ruled out by SN1987A Clock comparison wrong Group velocity is not info velocity Short cut via another dimension Neutrino speed is really the limit Clear evidence for pet theory x

33 Not your grandfather’s gravity www.timeandquantummechanics.com Non-barking Higgs If a Higgs particle is produced in a proton-proton collision, an LHC detector might infer what you see here. The four straight red lines indicate very high-energy particles (muons) that are the remnants of the disintegrating Higgs.

34 Not your grandfather’s gravity www.timeandquantummechanics.com How will it fall out? Emergent gravity Frame dragging Superluminal neutrinos Nobel for discovery of accelerated expansion of universe Higgs has fewer & fewer places to hide

35 Not your grandfather’s gravity www.timeandquantummechanics.com Richard Hammond Unknown Universe Leonard Susskind Black Hole War Anil Ananthaswamy Edge of Physics Richard Panek 4% Universe Lisa Randall Knocking on Heaven’s door References
