Einstein was Right and Continues to Enlighten Understanding of Universe #physics #maths #science #einstein

I’m fascinated by cosmology and quantum physics. Although I don’t speak Expanding universe since the Big Bangenough math to truly follow the science, I ran across a post that actually gives me an intuitive feel for Dark Energy – the almost mystical stuff that makes up a large part of the universe if we accept measurements of mass density wave-patterns. This post has tons of views – leave a comment – what do you think? Here’s the proposition”

Relativistic effects explain the observations evidencing the existence of Dark Matter around galaxies and galaxy clusters. When energy passes closer to galaxies it “slows down” due to gravitational time dilations.

The accumulative effect is a substantial increase in energy density when seen… far from the center of galaxies and that… is imperceptible for an observer within the galaxy. Gregorio Baquero

Visit Baquero to see the math, or just to read his narrative. He concludes:

There is no need for particularly special particles forming Dark Matter substance or even parallel universes’ escaped gravity to account for the extra gravity existing around cosmic structures. In a way, Dark Matter is just traveling energy.

I can get that – it makes sense to me. The speed of light is constant but the shape of space varies with mass. Gravity is the shape of space, thanks to energy interactions.

He doesn’t post his credentials or name collegeues, and I’m not competent to judge the math, but I admit I’m emotionally draw to Baquero‘s concluding sentence, which I paraphrased to title this post. Einstein hasn’t been left behind by quantum physics – not yet.

I’ve tried to capture my feelings in rhyme: Gravity Fights Dark Energy

Einstein’s Stardust #space #Poetry #poem #star

Stardust escapes a supernova

Stardust escapes a supernova

You may only know him
As the world’s most famous geek.
Einstein’s fame depends upon
A formula we can repeat

E = m c-squared

Your GPS just won’t work
Without his time dilation.
Satellites far above
Use relativity’s foundation.

If you like the gleam of gold
It’s re-emitted photons
That shift the sunlight’s frequencies
To yellow-reds we dote on.

Relativity explains
Light moves at finite speed.
If it were instantaneous
There’d be no light to see.

But it’s in supernovas
Where relativity
Overcomes quantum effects,
Creates the stardust,
To make,
And me.
