Did a Pre-Big Bang Species Cause the Big Bang Theory?

In summary, the conversation discusses the possibility of a pre-Big Bang species reaching light speed and creating an infinite mass that drew everything in the universe into one explosive event. The Standard Big Bang theory is unable to explain the low translational velocity of galaxies and the Inflationary Big Bang theory attributes the bang to negative pressure and the cosmological constant. The concept of infinite energy and mass needed to achieve light speed is still undefined as there is a search for the missing mass and energy of the universe. The validity of the Doppler Effect as evidence of expansion is also questioned.

Day-dreaming the other day, I postulated a possible explanation for the controversial Big Bang Theory. Because an object attains infinite mass when it reaches light speed, is it possible that a pre-big bang species reached light speed (or near) and the affected object achieved infinite mass (or near), effectively drawing everything in the universe to it, in one all-encompassing bang? Please forgive me if my hypothesis lacks consistency or sense, because of my relatively poor science background.

Welcome to Physics Forums, Plagosus.
Usually, these kinds of topics are discussed in the "theory development" forum.
I'll move it there now.

Plagosus,

The Standard Big Bang created not just matter but also radiation (photons), which were light speed from the beginning until now. This theory could not explain why matter in the forms of planets, stars and galaxies do not have high translational velocity. As a matter of fact, the galaxies are not really moving, it's the surrounding space that is expanding. And this expansion is greater than light speed the farther away the galaxies relative to our observations.

The Inflationary Big Bang attributed the bang to the existence of negative pressure creating the inflaton field. This negative pressure is similar to the force of antigravity.
And it is related intimately to the cosmological constant [itex] \Lambda[/itex] of general relativity.

Thanks for the explanation, and sorry for posting in the wrong forum.

When physicists talk of the infinite amount of energy needed to attain light speed, and the infinite amount of mass created as a result, are they describing infinite as the total energy and mass in the universe, because is there not a finite amount of the two?

Cosmologists are still looking for the missing mass (dark matter) and energy (dark energy) that the universe should have in order to form a closed spacetime geometry. That is to say that [itex] \Omega [/itex] greater than unity. The omega is defined as the ratio of the observed mass-energy density of the universe to the critical density needed for each geometry.

Plagosas - Infinite means 'undefined'.

BBT is still an unproven theory, based on the premise that stellar redshift is due to the Doppler Effect, (an expanding universe); however there are numerous other causes of redshift, and the type of redshift apparent in starlight may very likely be due to either the Compton Effect, or Shapiro Effect

so don't be so sure there ever was a Big Bang or that the universe (or even the visible universe) is expanding

nobody knows one way or another
since no one was there to see it happen

"Infinite", Plagosus, means "undefined", ergo, any statement that "the mass of a particle achieving the speed of light becomes infinite" is merely a confession of self-ignorance of what really does happen. Don't ask me, hey, I was in Chicago went all that went down.

to discount the doppler effect as evidence of expansion challenges the validity of the doppler effect. when you offer a better explanation [along with the math], i will listen.
 

1. What is the "Big Bang" theory?

The Big Bang theory is a scientific explanation for the origin and development of the universe. It proposes that the universe began as a single, extremely dense and hot point, known as a singularity, and has been expanding and cooling down ever since.

2. How does the "Big Bang" theory explain the formation of galaxies and stars?

The Big Bang theory states that as the universe expanded, matter and energy began to clump together due to gravity, eventually forming galaxies and stars. This process is still ongoing, as new stars and galaxies continue to form.

3. Is the "Big Bang" theory the only explanation for the origin of the universe?

No, there are other theories that attempt to explain the origin of the universe, such as the steady state theory and the oscillating universe theory. However, the Big Bang theory is currently the most widely accepted and supported by evidence.

4. What evidence supports the "Big Bang" theory?

There are several lines of evidence that support the Big Bang theory, including the observation of the cosmic microwave background radiation, the abundance of light elements in the universe, and the redshift of distant galaxies. These observations are consistent with the predictions of the Big Bang theory.

5. Can the "Big Bang" theory explain the existence of dark matter and dark energy?

Yes, the Big Bang theory can explain the existence of dark matter and dark energy, which are both important components of the universe. Dark matter is thought to make up a significant portion of the total mass in the universe and its presence can be inferred through its gravitational effects on visible matter. Dark energy, on the other hand, is believed to be the force responsible for the accelerating expansion of the universe.
