14 BILLION years ago…………..and this concept continues to be the holy
Grail of Science

Matter is neither created or destroyed
• Where did the first matter come from?
• Popcorn lab…..Was matter conserved?
• Established in 1789 by French Chemist Antoine Lavoisier
• States that mass is neither created nor destroyed in any ordinary chemical reaction.
• Or more simply, the mass of substances produced (products) by a chemical reaction is always equal to the mass of the reacting substances (reactants).

The secrets s of our past and the secrets of our future are locked into
this one moment of time
• Cities, forests, air, water, and yes; even people are made of matter and this
mattermatter originated on Earth as a result of the BIG BANG
Dark Matter

Big Bang….the defining moment of our Universe. • Every stars,
planets, every atom, every blade of glass…………..every drop of water originated from the Hydrogen from the Big Bang….

How do we see the Past…??
• As we travel deeper into deep space, we are actually seeing the past and getting closer to being able to witness the beginning of time. We arrive back at the moment that the Universe began?

Why are we here? Where did we come from?
• Why did it bang? • What bang• What was there
before the bang?• Where did energy
come from? • Does the Universe
have a definite beginning and a definite end?

Greatest Mystery of all time?
• Origin of Big Bang• Learning more and
more thanks to technology…Hubble!
• Are we just one bang out of many big bangs……..many other Universes?

Discovery: First Evidence of Big Bang
• 1920- things started changing
• 1929- Edward Hubble from Mt Wilson observatory ( LA): discovered that galaxies are not stationary…they are moving away at VERY high speeds.

Hubble’s LAW: the Universe is Expanding
• Must have started from a single point
• How do we know it is expanding? Like watching a video tape on rewind. Going backwards to see what happened?
![Page 11: 14 BILLION years ago…………..and this concept continues to be the holy Grail of Science](https://reader036.vdocuments.site/reader036/viewer/2022081516/551440045503466d1a8b5758/html5/thumbnails/11.jpg)
Basics…..
• What is a light-year? • If a star is billions of light-
years away, then it took a billion years for its light to reach Earth.
• If we can see far enough away, we can see the beginning of the Universe
• Winding back the clock is only the first step.

Before Big Bang?Before Big Bang?Something out of Nothing
• How can something arise from nothing? (ancient philosophers)
• Laws of Physics contradicted?
• The first matter was infinitely small, dense, & intensely hot ( a millionth of a billionth of a centimeter in diameter)
![Page 13: 14 BILLION years ago…………..and this concept continues to be the holy Grail of Science](https://reader036.vdocuments.site/reader036/viewer/2022081516/551440045503466d1a8b5758/html5/thumbnails/13.jpg)
Creation: First Force
• All forces as we know it took shape
• First: Gravity• Space started Expanding-
faster than the speed of light (breaking the law of physics: Speed of Light)
• Millionth ( X4) of a second for the Universe to expand from size of an atom to baseball……
• Nothing can go faster than the speed of light but empty space in NOT matter…it is NOTHING

Plank Time…..(one second = a billion X5 Plank
times)• How small is Plank
time? • There are more units
of Plank time in one second that all the seconds that have passed since the Big Bang. 31+ million seconds in a year and it has been a billion years since the BB

Phase Two:Phase Two:Energy into MatterEnergy into Matter
Charles’s Law & Ivory Soap• As super heated
molecules move faster ( faster that light) and spread out, they begin to lose density as they spread out.
• Thus cooling • Condensing into
matter
