If the galaxies are all moving away at speeds of the big bang "explosion" which was moving at speeds defying physics. Because nothing could have altered that speed, should'nt galaxies be moving at the same speed?

In what way do you believe that the big bang created speeds that "defy physics" ?Nova said:... at speeds of the big bang "explosion" which was moving at speeds defying physics ...
I realize that the big bang was expanding rather than exploding, but at speeds faster than light.phinds said:In what way do you believe that the big bang created speeds that "defy physics" ?
I assume that your putting "explosion" in quotes means you realize that the BB was NOT an explosion, yes?

can you explain for me please?phinds said:And as Drakkith pointed out, this in no way "defies physics"

The universe only expanded faster than the speed of light briefly (from 10-36 to between 10-33 and 10-32 seconds after the Big Bang), known as Inflation, which began and ended before matter existed. During this brief period of Inflation, space/time expanded faster than the speed of light in order to give the universe such an evenly distributed temperature that we see today.Nova said:I realize that the big bang was expanding rather than exploding, but at speeds faster than light.
AGAIN, as Drakkith has pointed out, this was not a "speed", it was a rate and this is not semantics so you are adding to the confusion not clarifying things.|Glitch| said:The universe only expanded faster than the speed of light briefly (from 10-36 to between 10-33 and 10-32 seconds after the Big Bang), known as Inflation, which began and ended before matter existed.

The speed of galaxies refers to the rate at which they are moving through space. It is typically measured using redshift, which is a phenomenon where the light from a galaxy is shifted towards the red end of the spectrum due to its motion away from us. This shift can be used to calculate the speed of the galaxy relative to our own.
According to Einstein's theory of relativity, nothing can travel faster than the speed of light. However, this theory applies to objects moving through space, not the expansion of space itself. The speed of galaxies is not due to their movement through space, but rather the expansion of space between them.
The speed of galaxies does not necessarily defy physics, but it does challenge our understanding of the universe. The expansion of the universe, which is measured by the speed of galaxies, is governed by the laws of physics but we are still trying to fully understand this phenomenon.
The Big Bang theory states that the universe began with a massive explosion and has been expanding ever since. The speed of galaxies is a key piece of evidence for this theory, as the faster galaxies are moving away from each other, the more distant they are from each other and the closer we are to the beginning of the universe.
Yes, the speed of galaxies can change over time. The rate of the universe's expansion is not constant and can be affected by factors such as dark energy and the distribution of matter in the universe. Additionally, the speed of individual galaxies can also be influenced by gravitational interactions with other galaxies.
