I know Gliese 581 is like 20.4 LY away but Beta Pictoris is like 19.2 LY away and Epsilon Eridani is like 10.5 LY away.

Is it possible for a singularity to be observed in our universe - Big Bang Theory - or is a singularity a purely theoretical / mathematical phenomenon ?

Could a particle accelerator cause a singularity to occur ?

Dark is an expression of the absence of light - it is nothing, the same as zero, a vacuum and silence.

They are just ways that we describe the absence of something.

To ask the speed of dark, is the same as wondering how much zero weight a weight lifter could lift, or how we can build a machine to detect silence.

Speed of dark is just as ridiculous as asking the density of a vacuum, or how fast can a dead man walk.

Was not the uranium 238 here on Earth with a half-life supposedly of 4.47 billion years created during the supernovae of a previous first generation star? That would seem to mean that it first started decaying right after the explosion and all during the reassemblage of the nebulae material that formed the Sun and planets(no matter if it were from slow self amalgamation or helped along with nearby blast waves of other early supernovae). This "accretion time" has to be taken into account. This yet unknown accretion time is vital in trying to find the age of the Earth itself in my opinion. If the Uranium 238 was decaying for a billion years or more in the pre-solar nebulae for example, would we not have to alter the age minus a billion years. Lord Kelvin may have not considered radioactivity in his famous thermodynamical approximation of earth's age but I think we are ignoring the importance of accretion time of the pre-solar system nebulae. What sayeth the radiomectrically dated zircons

I read that space continues to expand. And I've heard that the moon is becoming farther away from earth.
