I heard that at the time of the big bang the universe expanded faster than the speed of light, can anyone back me up on this? and if it is true then does that mean that the speed of light is not the universal speed limit?
mathman said:The speed of light is the speed limit for objects that are moving. The expansion of space itself has no speed limit.
intel said:All maths and physics tells us that the SOL is the barrier, how can something be an exception to what is an axiom?
Inflation is a neat response to so much but is it based on the assumption given by mathman above??
mathman said:The speed of light is the speed limit for objects that are moving. The expansion of space itself has no speed limit.
Alex48674 said:but we can not have a car and push it past the speed of light.
kateman said:but exactly what is expanding?
... what is the border?
what if one was to reach the border and tried to pass through?
intel said:Can it be specified where the expansion of space happens?
It is not at the border, as there is none?
Can space we occupy be expanding faster than c? Is it that relativity exists as a framework inside a framework whose rules are different?
The Big Bang theory is the prevailing scientific explanation for the origin of the universe. It suggests that the universe began as a single, incredibly dense and hot point and has been expanding and cooling ever since.
The Big Bang theory is closely related to the concept of a universal speed limit because it suggests that the expansion of the universe is limited by the speed of light. This means that nothing can travel faster than the speed of light, which is approximately 299,792,458 meters per second.
The fact that light is the speed limit in the universe has several implications. It means that nothing can travel faster than light, and it also means that nothing can travel through space faster than the expansion of space itself. This is important because it helps scientists understand the behavior and evolution of the universe.
Scientists have determined that light is the universal speed limit through a combination of theoretical calculations and experimental evidence. The famous equation E=mc^2, proposed by Albert Einstein, shows that the speed of light is a fundamental constant in the universe. Additionally, experiments such as the Michelson-Morley experiment have confirmed the constancy of the speed of light.
Based on our current understanding of physics, it is highly unlikely that anything can break the universal speed limit. As mentioned before, the speed of light is a fundamental constant in the universe, and it would require a significant shift in our understanding of physics for this to change. However, some theories, such as the concept of wormholes, propose that there could be ways to travel faster than the speed of light by bending or warping space-time. These theories are still speculative and have not been proven.
