Question About Dark Energy

Click For Summary
SUMMARY

The discussion centers on the nature of dark energy and the expansion of the universe, specifically questioning whether matter from an explosion continues to accelerate indefinitely in a vacuum. It concludes that while matter initially accelerates outward, its velocity does not increase indefinitely due to the influence of temperature and friction. The conversation also clarifies that the Big Bang was not an explosion into pre-existing space, emphasizing the unique conditions of the universe's expansion.

PREREQUISITES
  • Understanding of cosmology concepts, particularly the Big Bang theory.
  • Familiarity with the principles of matter acceleration and velocity in physics.
  • Knowledge of vacuum conditions and their effects on matter behavior.
  • Basic grasp of dark energy and its role in the universe's expansion.
NEXT STEPS
  • Research the implications of dark energy on cosmic expansion.
  • Study the physics of explosions and matter dynamics in a vacuum.
  • Explore the Big Bang theory and its misconceptions.
  • Investigate current theories regarding the acceleration of the universe.
USEFUL FOR

Astronomers, physicists, and students of cosmology seeking to deepen their understanding of dark energy and the dynamics of the universe's expansion.

When there is an explosion, matter flies off in every direction. At first it is static, and then it accelerates, and keeps accelerating, until friction slows it down to a stop. In a vacuum would this matter continue to accelerate indefinitely? And could this be the cause of the continued expansion and acceleration of the universe?

During an explosion, matter is accelerated outwards. The velocity does not continue to increase forever. The expansion following an explosion has a radial velocity determined by the temperature of the matter.

And where do you suppose the force comes from for this continuing acceleration???

No. The Big Bang was not an explosion into a pre-existing space.
