When You Wish Upon A Star


I have to travel light, often without extra clothes. Fortunately the World Science Fiction Convention has many costumes on display. (Honestly, I am probably too thin to wear this.) Disney says, "If You Wish Upon A Star...Your Dreams Come True." Discovering the secrets of Space/Time is the best Sci Fi dream come true.

Using the Hubble Space Telescope and the Subaru telescope atop our Big Island, astronomers have discovered galaxies that formed barely 500 million years after the Big Bang! Galaxies formed around Black Holes with the mass of a million Suns. These supermassive Black Holes could not have formed by evolution of stars. They are primordial, formed from collapse of quantum fluctuations. Mass of a collapsing Black Hole is limited by the amount of the Universe within its reach. Size of primordial Black Holes is determined by a horizon distance related to the speed of light. The earlier we find these supermassive PBH's, the more evidence favours a changing speed of light.

Hi!

Is that a working Star Trek Tricorder you have there? What exactly are ther three functions of the tricorder, apart from video camera?

I think much of Star Trek is complete sci fi junk that lacks physical foundation in hard fact, but I liked the episode in the original series:

The City on the Edge of Forever,

where Kirk and Spock record Dr McCoy jumping through a time machine into 1930s Prohibition America using a Tricorder and built up replacement memory circuits with vacuum tubes. It's a nice story about the problems with pacifism when the alternative to war is not worth thinking about:

"McCoy accidentally injects himself with an overdose of cordrazine, a drug which makes him exhibit signs of paranoia and madness, while treating an ailing Sulu on the Bridge. Delirious, he beams down to a nearby planet's surface, with Kirk and a landing party on his heels.

"They are too late to stop the doctor from leaping through a living time machine called "The Guardian of Forever." At that moment, the U.S.S. Enterprise ceases to exist and the landing party is stranded. The Guardian explains that McCoy went back into Earth's history and changed it, thereby altering the future. Kirk and Spock go through the Guardian, to Depression-era America, a few days before McCoy is to arrive and change history.

"They encounter a social worker, Edith Keeler, who helps them find work to pay for the equipment Spock requires to build a tricorder. Unknown to Kirk and Spock, Edith has taken in the recently-arrived and ill McCoy. Kirk promptly falls in love with Edith and is devastated when Spock completes his tricorder and discovers that in order to repair history, they must let Edith Keeler be killed in an auto accident. If they allow McCoy to save her — as he did before — she will start an effective pacifist movement that will delay the United States' entrance into World War II, thus allowing Hitler's Germany to develop the atomic bomb first and conquer the planet."

HI Nigel: Some of those 1960's shows seem cheesy, but this blog is about having fun. I think the tricorder was an all-purpose recording and computing device. It forecast removable discs for memory. The unit I'm wearing just lights up and makes sound effects. The 1930's episode is fascinating because we have to make those kinds of decisions in our time.

One thing we all have to remember when wishing upon stars (or anything else) is that sometimes our wishes are answered in the most unexpected ways. Not that unexpected means disappointing. Sometimes surprises are very wonderful. May all your wishes come true in the most wonderful ways!

Hi Louise,
do you work and live there
aboard the USS Enterprise.

Or are all the pics from the same visit. I can see you are having fun

PS - something a tricorder can't do is take photos (and video) like modern 21st Century mobile phones.

Funny how we can send and receive text & images. More than the tricoder could.
