Universe expansion faster than light?

[mrxyz]

The speed of light is a constant. Yet the Universe's expansion seems to be getting faster and faster.

So my question is, when the speed of the expansion of the Universe reaches C the speed of light, what happens. Does it remain at that speed? Does it exceed it? Or does it slow down?

As I understand it, the speed of light is the upper limit of the speed of things moving in space and does not limit the speed at which space itself moves. Thus it is possible to conjecture that at some early stage of the universe, space did in fact expand at a speed greater than the speed of light.

Google "metric expansion" to explain it all

From what I understand, the fabric of the universe is expanding at a rate greater than the speed of light already. We can see the light from stars 46+ billion light years away and the big bang happened less than 14 billion years ago. You would think that the light from the stars 46+ billion light years away would take 46 billion years to reach us therefore disagreeing with how long ago the big bang happened, but the reason we can see the light from those stars is because they used to be much closer.

It's important to note that expansion of the universe and the motion of the objects within the universe are entirely separate concepts.

I can assure you that the expansion of the Universe is not faster than the speed of light. This is a common misconception that arises from the fact that the expansion of the Universe is not limited by the speed of light. In other words, the expansion of the Universe is not caused by objects moving through space, but rather by the stretching of space itself.

The speed of light is a fundamental constant in our Universe and is the fastest speed at which any object can travel. It is not possible for anything, including the expansion of the Universe, to exceed this speed. As the Universe expands, the distance between objects is increasing, but this does not mean that the objects themselves are moving faster than the speed of light.

Additionally, the expansion of the Universe does not slow down or stop when it reaches the speed of light. It continues to expand at a constant rate, known as the Hubble constant. This rate may change over time, but it will never exceed the speed of light.

It is important to note that the concept of the speed of light as a limit only applies to objects moving through space, not to the expansion of space itself. The expansion of the Universe is a complex and ongoing phenomenon that is still being studied by scientists. While it may seem counterintuitive, the fact that the expansion of the Universe is not limited by the speed of light does not violate any known laws of physics.
