Indeed, and this was during the radiation era. But the photons that drove the expansion were from the cosmic microwave background, not stars.mrspeedybob said:I remember Susskind, in one of his lectures on youtube, discussing the effects of radiation pressure on cosmological expansion.
Photons from one star can affect other stars through a process called stellar interactions. When photons are emitted from a star, they travel through space and can interact with other stars along the way. This can cause changes in the energy and movement of the other stars, affecting their overall behavior and appearance.
No, not all photons from a star will reach other stars. A significant portion of photons will be absorbed or scattered by interstellar dust and gas before reaching other stars. Additionally, the further away a star is from another, the weaker the influence of its photons will be.
Yes, photons from one star can play a significant role in the formation of other stars. When a massive star emits a large number of photons, it can trigger the collapse of nearby gas clouds and initiate the formation of new stars. This process is known as radiation-driven implosion.
The time it takes for photons from one star to reach another depends on the distance between the two stars and the speed at which the photons are traveling. For example, it takes approximately 8 minutes for photons from the Sun to reach Earth, but it can take years or even centuries for photons from one star to reach another star in a different galaxy.
Yes, the influence of photons from one star on other stars can be significant. Photons carry energy and momentum, and when they interact with other stars, they can affect their physical properties and behavior. In some cases, the influence of photons can even determine the fate of a star, such as in the case of a supernova explosion triggered by the radiation from a nearby star.
