Avaruudessa laajenevan valon vauhti kiihtyy vastavirtaan / The pace of light expanding ”in” space accelerates countercurrently. .

Niin, katsokaapa tämä video ja ihmetelkee tätä

Tuossahan nyt mittään ihmeellistä ole 😃

Työntyväthän laajenevat valotkin vastavirtaan toistensa kanssa, kiihdyttäen toistensa laajenemista ja näin laajenevien valojen vauhti kiihtyy vastavirtaan samassa suhteessa kuin aineet ja valot laajenevat 😃

”You’ve probably seen something similar countless times; the fish wriggles against the currents that push it backwards, slowly making headway until it turns and ducks out of the influence of the stream. Nothing special in that.

The only thing is, this particular fish is dead.

Yes, you read that right. No matter how lifelike it looks as it undulates across the tank, that same trout would just go belly-up if the current were switched off. So how can it possibly swim upstream?

A team of researchers from MIT and Harvard were equally surprised when they happened upon this phenomenon by accident. They’d been studying the way live trout conserve energy by swimming behind obstacles that block the current*, and unintentionally placed a dead fish in the experimental setup. When they took a closer look, they were stunned.

“It was incredible, very counterintuitive,” MIT researcher Michael Triantafyllou says, describing the shock he felt upon seeing the fish swimming upstream. He explains that while he knew trout were good at conserving and even extracting energy, he had no idea that they’d be able to extract enough energy from the surrounding fluid to swim upstream without expending any of their own energy. Immediately, the team started to investigate this new, seemingly impossible phenomenon.”

So, take a look at this video and wonder about this

After all, there is no miracle in that now

After all, even expanding lights push countercurrently with each other, accelerating the expansion of each other, and thus the pace of the expanding lights accelerates countercurrently in the same proportion as substances and lights expand 😃
