What Would Happen if Asteroid Bennu Were to Impact the Earth?


Yesterday, the media reported widely on the upcoming launch of OSIRIS-REx. While many of these reports were accurate and informative, a few of the headlines were a little misleading. For example:

NASA Spacecraft Set to Explore Giant Asteroid That Could Destroy Earth

Fortunately, as the news cycle progressed, these inaccuracies were corrected:

No, Asteroid Bennu Won’t Destroy Earth

I thought it would be useful to summarize the effects of a Bennu impact. The Minor Planet Center classifies Bennu as a Potentially Hazardous Asteroid because it has a diameter larger than 150 m and a minimum orbit intersection distance (MOID) of < 0.05 Astronomical Units (abbreviated AU and equal to the average distance between the Earth and Sun) with the Earth. Bennu has a mean diameter of 492 meters and its MOID is 0.003 AU. The MOID will steadily decrease resulting in a potential Earth impact during the later decades of…

Topic023: Where Particles Begin – and End, Bill Tifft, 7/04/16

Topic_023_S4T4c Z W section of book chapter 4, table 4

Topic_021_LeptonFg Table of fits to the Lepton

Matter is a dynamical assembly of packets of passive energy. The 1 2 4 triad is apparently that basic package, not only a basic energy unit but a basic structural block for forming particles. The triad involves three consecutive doublings which appears to be the maximum doubling range possible within an individual structural unit. Quarks are then built upon multiples of triads, as will be shown subsequently in Topic024, to generate quarks and leptons, where the leptons represent limiting forms for quarks and both light and heavy mesons. Hadrons, mesons, bosons and baryons, are dynamical assemblies of quarks. The stable proton is, in a sense, the limiting form for baryons, but in fact is assembled from quarks, already limited.

The Zo and associated W Gauge…

For Immediate Release: Time in Cosmology Advisory Board

For Immediate Release
June 28, 2016

Advisory Board Established

Ret. Commander Robert Hoot Gibson, NASA Astronaut fighter pilot, and aeronautical engineer.  Associate Mathematics Professor, and Co-founder and President of The Physics Factory, Bruce Bayly.



We have an addition to the Board!

Our team now includes Professor and Head of the Philosophy Department at the University of Arizona, Michael Gill!  He has written two books, Humean Moral Pluralism and The British Moralists on Human Nature and the Birth of Secular Ethics, and continues to write about the history of ethics, contemporary ethical theory, and medical ethics.

Meet the Time in Cosmology Advisory Board!

Tucson, Arizona, June 27, 2016 – Time in Cosmology (TiC) is pleased to announce the establishment of an Advisory Board.  We recognize and thank individuals on the Advisory Board for graciously donating their time to help with TiC future endeavours.  We are honored to introduce Ret. Commander Robert “Hoot” Gibson, NASA Astronaut fighter pilot, aeronautical engineer; and Bruce Bayly, University of Arizona Mathematics Associate Professor, and Co-founder and President of The Physics Factory, as the TiC Advisory Board.

WHAT: Advisory Board Established
WHO: Ret. Commander Robert Hoot Gibson, NASA Astronaut fighter pilot, aeronautical engineer.
Associate Professor Bruce Bayly, University of Arizona Mathematics, and Co-founder and President of The Physics Factory.
WHEN: Monday, June 27, 2016, 9:00 AM
WHERE: PO Box 41692
ORGANIZATION:  Time in Cosmology

The mission of TiC is to bring together researchers, post-doctoral, graduate, undergraduate students, and other interested parties in astronomy, physics, philosophy, mathematics, and cosmology in order to inspire STEAM in students, academia, and the local community.

TiC is a 501(c)3 collaborative group involved in scientific research and education. The group was founded in 1996. TiC is organized around established principal scientists, joined for the purpose of fostering research, communicating that work, and providing educational opportunities for persons of all ages who may be entering the scientific profession or are simply interested in TiC’s fields of scientific investigation.

Topic022: The Fundamental Forces, Introducing The Triad, Bill Tifft, 6/15/16

Topic_022_Formula1 Fine Structure Constant

Topic_022_S4T8 Book chapter 4, table 8

Before proceeding to discuss the nature of quarks, or even finish discussing leptons and light mesons, I need to introduce the `triad’, the key to defining the fundamental forces. Technically I have already introduced the 1 2 4 triad but historically it was originally recognized in the early years of QTC when the forces were defined. The full significance of the triad within QTC came later with the study of the nature of quarks as discussed in my book and the following Topic023. (For book information or acquisition see Post001 and Post002.) The key to defining the fundamental forces involves the `fine structure constant’, designated as `Alpha’, which measures the relative strength of the forces. Alpha measures the ratio between the interaction strength of a force and a fundamental reference strength…

Topic_021_S4T7_meson Table 7, section 4, from book chapter 4

One of the best actions possible in support of QTP theory is to provide good answers to puzzles in existing theories. QTP, through QTC and QTPP, has been very effective in that process. QTC speaks for itself through earlier Topics, with more to come, as the terminal figure of Topic020 illustrates. The ability to predict energy level patterns which define masses, properties (such as magnetic moments) of particles, and interrelationships between classes of particles is a unique and remarkable accomplishment. The baryon class of hadrons (quark based particles) find their home in tightly defined 3-d quantum energy levels intimately tied to a 3-d 64 Planck based doubling structure. This is possible because the structure is compatible with Keplerian vector dynamics in 3-d space. There…
