Time travellers could use parallel dimensions to visit the past, scientists claim

Itf it is a different dimension, then the point of identity would be the point at which two identical parallel paths diverged, I think. There seems to be no possible solution to the parodoxes inherent without assuming we are all bits in a computer program.

I corrected myself above. It's red shift physics that determine how fast something is moving away from our perception, not doppler effect which deals with sound waves.

Yes, I know what a light year is. It's been seared into my mind since reading sci-fi novels at 13 or so. I'm 67.

And yes, our best telescopes still can't see the end of galaxy/nebula/gases expansion. When and if they can, it will be huge news that they found the last galaxy and the emptiness beyond.

BTW, I've read and heard that the Singularity was the size of a basketball or baseball. You say it was the size of pin head. No wonder the poor thing exploded...haha. Humans will never understand how the Singularity came into being.

I've read a convoluted hypothesis that claims it COULD appear out of nothingness with some reasoning that atoms could appear from the coldness and darkness of space. Something similar how certain chemicals on Earth combined to form single cell lifeforms. I could possibly buy into that life form theory. Just not buying the Singularity spontaneously poofing into existence. How would a neutron, proton (positive charge), electron (negative charge), neutrinos, isotopes, etc, just suddenly appear?

And yes, I've read that your pin head or my baseball Singularity was only made up of hydrogen or helium? atoms, and upon expansion, our known elements were created in a gazillionth of second after the big bang. It all seems to have been directed.

I’ve read that your pin head or my baseball Singularity was only made up of hydrogen or helium? atoms, and upon expansion, our known elements were created in a gazillionth of second after the big bang.

“It is now known that the elements observed in the Universe were created in either of two ways. Light elements (namely deuterium [an isotope of hydrogen], helium, and lithium) were produced in the first few minutes of the Big Bang, while elements heavier than helium are thought to have their origins in the interiors of stars which formed much later in the history of the Universe. Both theory and observation lead astronomers to believe this to be the case.”
