SUMMARY

The discussion centers on the implications of solar energy production and its impact on the universe's energy balance. Participants argue that the vastness of the universe and its continuous expansion prevent an overwhelming accumulation of energy from stars. Key points include the Earth's ability to both receive energy from the Sun and radiate energy back into space, and the significance of redshift observations in confirming that galaxies are moving away from us, indicating the universe's growth.

PREREQUISITES
  • Understanding of solar energy production and radiation
  • Familiarity with cosmic expansion concepts
  • Knowledge of redshift and its implications in astronomy
  • Basic principles of thermodynamics related to energy transfer
NEXT STEPS
  • Research the concept of cosmic expansion and the Big Bang theory
  • Explore the implications of redshift in understanding the universe's structure
  • Study the principles of energy conservation in astrophysics
  • Investigate solar energy dynamics and its effects on planetary systems
USEFUL FOR

Astronomers, astrophysics students, educators, and anyone interested in the dynamics of solar energy and cosmic expansion.

Sun is constantly producing energy from the particles inside it. It is not using the energy from out. So if this is true, as lots of energy is coming to the universe every day, isn't it dangerous as on day energy in the universe will be soo great to burst the universe as energy is entering but not leveing the universe??

Good question !
Two arguments why it isn't running out of hand on short notice:
1. The universe is huge in comparison to the amount of energy stars radiate out
2. And if that isn't enough: the universe is growing at a tremendous rate as well

1)When the Earth was created, it had enough energy to do all the work it had to do and still more energy is supplied. Does the energy coming still will not get out of control?
2)How do we know that universe is growing as I believe that no one has ever seen the boundary of universe. If no one has seen the ends, bow can we know that these ends ar moving away?
 
Hi,
1) the Earth receives energy from the sun (quite a lot), but it also radiates energy out into the universe
2) You're a quick reader if you already absorbed the wiki link I gave :rolleyes:
You should do some searching the internet on your own ! I grant you there's a lot of humbug, but there are good sites at any level of knowledge.
But for this once: the redshift has inspired us to realize galaxies are moving away from us

I'll be looking over the internet. Thank you.
 
You're welcome. Good hunting !
