My FTL Challenge

Thoughts?

 

[Tone]

Of course our physics aren't complete. No science is.

So, yes, I believe there are forces that move increasingly faster towards the eternal state.

*How fast is the twinkling of an eye?

 

[Tone]

"A TWINK (twinkle) is a reflected particle of light seen in the eye. Most of us have noticed a twinkle in someone’s eye . . . that reflected light we observed traveled at 186,000 miles per second (speed of light). That little ray of light entering the eye and then being reflected occurs in about a billionth of a second. A twinkle is pretty fast don’t you think!?"
A WINK, A BLINK & A TWINK!

This Is How Distant Galaxies Recede Away From Us At Faster-Than-Light Speeds

This phenomenon is well understood.

 

[AV1611VET]

This phenomenon is well understood.

Then why does the narrator, at 01:04, say, 'But nothing travels faster than light'?

 

[Tone]

I would also imagine that the Creator would have to speak faster than the speed of light.

Sound takes on a new dimension with God.

Exodus 2:23 And it came to pass in process of time, that the king of Egypt died: and the children of Israel sighed by reason of the bondage, and they cried, and their cry came up unto God by reason of the bondage.

Thoughts?

Sensational nonsense. A.k.a. "click bait" on the net. A lot of statements in this clip are erroneous and/or misleading.

Thoughts?

This general observation, first made about a century ago, is part of what led us to understand that space is expanding, and thence to the Big Bang model.

Hmmm ... interesting.

 

[sjastro]

Thoughts?

What a dumb video.
Objects with a redshift z > 1.46 have recessional velocities which exceed the speed of light; there is nothing unusual about this.
The dumbness aspect is using the concept of the Alcubierre drive as an explanation which is a piece of science fiction and has no relevance.

Do things move faster than light?

 

[AV1611VET]

What a dumb video.

It was put out by the Science Channel.

Objects with a redshift z > 1.46 have recessional velocities which exceed the speed of light; there is nothing unusual about this.

You mean, only on paper?

The dumbness aspect is using the concept of the Alcubierre drive as an explanation which is a piece of science fiction and has no relevance.

So it's a lie?

 

[In situ]

Then why does the narrator, at 01:04, say, 'But nothing travels faster than light'?

My guess is sensational, and ignorant, reason. My feeling is that the producer is more interesting in earning money by manufacture sensational "news" where there is none rather than producing accurate science.

You wont be able to tell if it did.

If I call myself a doctor, does that make me a doctor? (Popular science is not science, but entertainment).

So it's a lie?

Calling it a lie is a strong word, but it is misleading and ignorant.

It is click bait nonsense.
Redshift is a measurement determined from the spectrum of galaxies.

 

[Hans Blaster]

It is click bait nonsense.
Redshift is a measurement determined from the spectrum of galaxies.

It's sort of worse than that. Since this starts with one of the deep fields (not sure which one) the redshifts are measured with broad-band photometry and not even spectroscopy. (Most of the objects in such fields are faint enough to require reallllly long exposures to measure if it's even possible at all.)

 

[Nithavela]

Then why does the narrator, at 01:04, say, 'But nothing travels faster than light'?

Because nothing does.

Some things just appear to travel faster than light because of observation errors.

It's like measuring a horse with a broken speed laser that shows 10 times the actual speed and then making a documentary about a miracle horse that could race a sportscar.

Isn't the science channel the one that hosts a pawn shop owner in his most well-liked shows?
