3. Dark Energy & Flow 3 Part 1 – Dark Energy

4. Dark Energy & Flow 4 Discovery of Red-Shift of Spectral Lines in Astronomical Observations In about 1929, Edwin Hubble and several other scientists discovered that the spectral lines in the light received from distance galaxies are all shifted toward red light end of the spectrum Edwin Hubble further discovered that the amount of red-shift is proportional to the distance of galaxy from us

6. Dark Energy & Matter 6 Expanding Universe A red-shift can occur when the light source is moving away from an observer, similar to the Doppler shift that changes the perceived frequency of sound waves. The observed red-shift implies that: –Galaxies are running away from us, –The receding speed of a galaxy is proportional to its distance from us, and –Universe is not static, but is expanding

7. Dark Energy & Matter 7 Expected Effect of Gravity on Expanding Universe All matters have gravity pulling on each other Such gravity pull is expected to slow down the expansion of universe In 1998, two independent teams* of scientists did two independent astronomical measurements to try to measure the rate of slowing down of expanding universe (i.e. to measure the ultimate fate of our universe) * Two teams: the Supernova Cosmology Project at the Lawrence Berkeley National Laboratory and the High-z Supernova Search Team

8. Dark Energy & Matter 8 Surprise! However, these two teams of scientists and the whole world were all surprised in 1998 to find that the expansion of universe is NOT slowing down, but is accelerating. These two independent teams of scientists were scared and thought that they might have some errors in their measurements. But their careful checks found no errors in their two independent sets of measurements All scientists and astronomers have been in a state of collective bewilderment since this surprising discovery in 1998.

9. Dark Energy & Matter 9 What to do with such a big surprise? - Dark Energy The key question is what is causing such acceleration of expansion of universe? For the time being, scientists have to postulate a “Dark Energy” that is a hypothetical form of energy that permeates all of space and tends to increase the rate of expansion of the universe.

10. Dark Energy & Matter 10 Part 2 – Dark Flow

11. Dark Energy & Flow 11 Expansion of Universe For many years, astronomers assume that: –Space is expanding in a uniform way—at the same rate in every cosmic locale –Big Bang growth marches at the same pace everywhere –Such assumption is quite natural and reasonable if there is only one universe

12. Dark Energy & Matter 12 New Surprise and New Challenge on Historical Concept of Expanding Universe By analyzing data collected by the Wilkinson Microwave Anisotropy Probe (WMAP) satellite, Alexander Sasha Kashlinsky of NASA’s Goddard Space Flight Center discovered surprising Dark Flow in 2008 Dark Flow represents the movement of hundreds of galaxy clusters at about two million miles per hour in the direction of a patch of sky between the constellations Centaurus and Vela. Dark flow extends out as far as 2.5 billion light years away. With such a large scale, it slashes through a significant chunk of the observable universe.

13. Dark Energy & Flow 13 Surprising Dark Flow Why the expansion of universe is NOT uniform everywhere? What causes such observed huge Dark Flow in the universe?

14. Dark Energy & Matter 14 Part 3 – Parallel Universes and Inter-Universe Coupling Gravity

15. Dark Energy & Flow 15 Concept of Parallel Universes with Inter-Universe Coupling Gravity Parallel Universe B Parallel Universe C Our Universe A Parallel Universe D Parallel Universe E

16. Dark Energy & Matter 16 Dark Energy is Inter-Universe Coupling Gravity Our Universe A is surrounded by many other parallel universes B, C, D, E, etc. I believe that the Inter-Universe Coupling Gravity from other parallel universes is causing the accelerated expansion of our Universe A Therefore, I propose that Dark Energy is Inter-Universe Coupling Gravity

17. Dark Energy & Matter 17 Non-Symmetric Pulling from Inter-Universe Coupling Gravity - 1 There is no reason that the distribution of other parallel universes must be perfectly symmetrical with respect to the center of our Universe A Such non-symmetrical distribution of other parallel universes relative to the center of our universe A means that the Inter-Universe coupling gravity from other parallel universes is not symmetrical with respect to the center of our Universe A

18. Dark Energy & Matter 18 Non-Symmetric Pulling from Inter-Universe Coupling Gravity - 2 Therefore, the accelerated expansion of our Universe A is not symmetrical, not uniform, and not homogeneous. Therefore, I propose that the observed Dark Flow is caused by such non-symmetric pulling from Inter-Universe Coupling Gravity
