When the observable universe was the size of a baseball, did its gravity (field?) extend to (as opposed to towards) infinity?
BRIAN VORHIES said:Can the question be stated in this way?
Earlier in the expansion of the universe, when there was less empty space between matter, was the influence of gravity greater than it is now?
BRIAN VORHIES said:did time pass at a slower rate, did entropy happen at a slower rate?
BRIAN VORHIES said:It seems to me that, being within the universe, we wouldn't be able to measure a difference.
BRIAN VORHIES said:if we could hold the past universe in our left hand, and the present in our right, and watched
BRIAN VORHIES said:Can't the answer be extrapolated mathematically?
BRIAN VORHIES said:If time moves more slowly at sea level than it does on a mountain top
The "Gravity of a Baseball-Sized Universe" concept is a hypothetical scenario where the entire universe is condensed to the size of a baseball, with all of its mass and energy compressed into this small space. It is used as a thought experiment to explore the properties and effects of gravity on a cosmic scale.
In a baseball-sized universe, the force of gravity would be incredibly strong due to the immense amount of mass and energy packed into such a small space. Objects within this universe would experience a strong gravitational pull towards the center, making it difficult for them to escape or move away from each other.
Yes, in a baseball-sized universe, the extreme gravitational forces would cause time and space to become distorted. Time would slow down significantly and distances would appear to be much shorter than in our current universe. This is a result of the warping of spacetime by the strong gravitational field.
The concept of a baseball-sized universe highlights the incredible power and effects of gravity on a cosmic scale. It also raises questions about the nature of the universe and the role of gravity in shaping it. It can also help scientists better understand and study the behavior of gravity in extreme conditions.
No, a baseball-sized universe is purely a hypothetical concept and not possible in reality. The laws of physics and the limits of our universe prevent such a scenario from occurring. However, studying this concept can provide valuable insights into the nature of gravity and the universe as a whole.
