anonymous asked:

How do you combine science and religion? They're basically the opposite. I wish I could without feeling one is a lie.

Ahhhhhhh, nonny, nonny, nonny.

The answer is because, truly, nothing fuels my love for & faith in my religion more than science. And nothing keeps me motivated & driven to keep learning and working in science more than my religion.

I don’t try to analyse my Gods with the scientific method, the same way I don’t try to analyse my experience of being in love. Even if there is specific phenomenology one could identify, neurotransmitters being released, activity in parts of the brain, that’s not what those things are fundamentally about. Science does not hold all the answers to all the facets of the universe or life or the human condition. And a good scientist must always remember the limits of her theory and her experimentation.

But -

On Sunday night I watched David Attenborough’s Planet Earth II and had tears in my eyes at the infinite diversity and beauty of the natural world. Watching thunder clouds rolling over steppes and feeling filled up with love for Sif and Thor. Every sequence of predators chasing down prey resonating so deeply with the part of me that works with the Wild Hunt. And looking at every incredible living thing shown and knowing - that by the wonder of evolution - we are all cousins - all related - our ancestors are the same.

But everything I learn about molecular biology, the incredible, incomprehensible complexity of every cell in every living organism and how they interact - all hewn out of twenty amino acids, coded by four bases, all evolved from a single cell across billions of years - just increases my sense of awe and wonder and faith in the Gods. This is what they gave us.

As does the stunning beauty and elegance of the laws of physics. The wave equation. Dirac’s equation that knew more than he did. The energy-matter equivalence. Quantum-electro-dynamics, which is accurate to a degree equivalent to measuring the distance between New York and Los Angeles to within the breadth of a single hair. The fact that I can look up at the night sky and see light from millions of years ago. 

This is beauty, this is poetry, this is magic, this is where I find my Gods.

The Question That Could Unite Quantum Theory With General Relativity: Is Spacetime Countable?

Current thinking about quantum gravity assumes that spacetime exists in countable lumps, like grains of sand. That can’t be right, can it?

One of the big problems with quantum gravity is that it generates infinities that have no physical meaning. These come about because quantum mechanics implies that accurate measurements of the universe on the tiniest scales require high-energy. But when the scale becomes very small, the energy density associated with a measurement is so great that it should lead to the formation of a black hole, which would paradoxically ruin the measurement that created it.

These kinds of infinities are something of an annoyance. Their paradoxical nature makes them hard to deal with mathematically and difficult to reconcile with our knowledge of the universe, which as far as we can tell, avoids this kind of paradoxical behaviour.

Can LIGO test quantum gravity?

“The dynamics of a black hole merger and the way gravitational waves travel is sensitive to even smallest deviations from general relativity, like for example violations of the equivalence principle or the possibility that the graviton is not exactly massless. Bimetric gravity, higher-order modifications of general relativity, additional long-range interactions, or the gravitational aether – all these models will have to pass additional tests now. Undoubtedly, some will be winners (most likely where the disagreements from relativity’s predictions are too small to rule out), and some will be losers. And maybe one of them will turn out to supersede Einstein’s masterwork.”

General relativity makes very specific prediction for what the curvature of space should be at the event horizon of a black hole, and for the consequences to spacetime are for a mass accelerating outside, near and through it. However, a fully quantum theory of gravity is needed to understand what happens at or near a black hole’s singularity. In some variations of quantum gravity, though, there are departures from Einstein’s theory that will extend farther out than the singularity itself, and these variations may be testable by LIGO. As more events come in, we can look for deviations from general relativity’s predictions, and if we find them, perhaps we’ll uncover the first evidence for gravitational physics beyond the scope of Einstein’s relativity after all.

How we escaped the Big Bang: New theory on moving through time

Associate Professor Dr Joan Vaccaro, of Griffith’s Centre for Quantum Dynamics, has solved an anomaly of conventional physics and shown that a mysterious effect called ’T violation’ could be the origin of time evolution and conservation laws.

“I begin by breaking the rules of physics, which is rather bold I have to admit, but I wanted to understand time better and conventional physics can’t do that,” Dr Vaccaro says.

“I do get conventional physics in the end though. This means that the rules I break are not fundamental. It also means that I can see why the universe has those rules. And I can also see why the universe advances in time.”

Hello, fellow science lovers!

I’ve had quite a few new followers since the last time I formally introduced myself, so I thought I’d take a few moments to do just that!

I’m Devon, the blogger and scientist behind Scientists are People Too. Currently, I’m a fourth year graduate student at UCLA working on a PhD in physical chemistry. For three years, I did ultrafast spectroscopy to look at the condensed phase dynamics of simple molecules (and bashing my head against what turned out to be a dead-end project -_-).

However, this past summer, my wonderful husband and I found out that I was going to have a baby! Since my ultrafast work involved some pretty nasty chemicals, my PI helped me switch over to a theory project. I’ve thus spent the past few months working on mixed quantum/classical molecular dynamics simulations and preparing for parenthood!

I’ve been less active on here recently due to the holidays plus the fact that I’m due to give birth any day now, but I’ve got lots of great science blogging planned for the near future!

What my friends think I am thinking: “The quantum dynamics of interstellar travel are far beyond the comprehension of space-time to even correlate, thus deeming consciousness throughout light-travel based speed nearly non-functional. However, if one where to account for the deficiencies of….”

Me, a straight A student who graduated top 10 in my class, president of the Student Council Association in 9th grade, who now holds both a college major and minor with club honors, is actually thinking: “Is thrussy pronounced ‘thr-uh-see’ or “thr-OO-see?”

anonymous asked:

Ayyyyy you know there's a Singaporean DC superhero called Jenny Quantum?? Her costume is literally a Singapore flag crop top and a jacket and she was some pretty odd powers

I DIDN’T KNOW THAT’S SO COOL!! (but she’s an american citizen now) 

Jenny Quantum was born January 1, 2000 in Singapore, during the death of Jenny Sparks.  She is the current leader of superhero team, The Authority, windstorm universe. 


  • Spirit of the 21st Century: She was born “with the century” - on the stroke of midnight on New Year’s Eve of 2000. Normally as a Century Baby grows they displayed certain superhuman abilities and skills, as well as immortality (not aging beyond her 20’s until the century is over). In Jenny’s case she displayed her powers a little after birth, whereas her previous incarnations only developed their abilities at 19. As with all Century Babies, it has been theorized that they act as an immune system for the planet; her very existence protecting Earth. As such she represents an aspect of the century into which she is born.
  • Quantum Reality Manipulation: Jenny has the power to manipulate reality at the quantum level allowing her to achieve anything she can conceive of at the quantum molecular level. Jenny has the ability to manipulate the laws of quantum dynamics, manipulate ambient energies, and accelerate her own age. Her father Apollo once described her as having the ability to do “basically anything”.
  • Chronokinesis
  • Dimensional Travel
  • Energy Projection: As a newborn she produced an energy blast of sufficient strength to disintegrate the legs of a giant who was attempting to kill her.
  • Flight
  • Force Field
  • Phasing
  • Probability Manipulation
  • Teleportation: She has the ability to teleport between points on Earth and also other dimensions.
  • Immortality: She has stopped aging at nineteen and will most likely remain this way until her death. She is assumed to have at least a 100 year lifespan, not aging anymore at adulthood. Theoretically, she will live on through the next Spirit of the 21st Century.
