"Size = the entire known Universe, about 47 billion light years."

So we have the big bang theory of creation which states that the universe is 14 billion years old. The universe, expanding at no faster than the speed of light, should be, at maximum, 28 billion light years across.

Wiki says (speed of light):

"The speed of light in the vacuum of free space is an important physical constant ..."

"The speed of light is of fundamental importance in physics. It is the speed of not just light, but of all electromagnetic radiation, as well as gravitational waves and anything having zero rest mass."

"This theory together with the principle of causality requires that no matter or information can travel faster than the speed of light."

The speed of light is, I was led to believe, one of the immutable laws of physics.

Now we have this: Also from Wiki (size of universe):

"Astronomical observations indicate that the universe is 13.73 ± 0.12 billion years old. It's diameter is at least 93 billion light years..."

So, is the universe 28 billion light years across, or is it 47 billion, or is it 93 billion?

Physicists, when asked to 'splain this, say that the difference is due to "cosmic inflation" or did thay mean "comic" inflation?" And just what is cosmic inflation?

Again, from Wiki:

"In physical cosmology, cosmic inflation is the idea that the nascent universe passed through a phase of exponential expansion that was driven by a negative-pressure vacuum energy density."

There's more bullshit, of course, but this is already turning into a snoozer, so I will spare you.

Pysicists: They say the darndest things.
