NASA scientist says the speed of light may not be a constant

[Swordsmyth]

Louise Riofrio is involved in a project that will put an atomic clock into the International Space Station to “verify” her theory.
She reached the conclusion that the speed of light is changing while working at NASA.
The scientist analysed lasers that bounced off reflectors left by astronauts on the moon, which appeared to show the moon was moving too fast.
But – when she compared it to various experiments on Earth using fossils, observations of ancient eclipses and computer simulations – she found it was actually moving more slowly.


It led her to believe that “the speed of laser light slowing had caused the moon to appear to be moving faster”.

The scientist also said her theory could allow warp speed – similar to that seen in cult series Star Trek – to occur in space.
“Warping space to reach other solar systems faster than light is definitely something we might do some day,” she added.

Duh.

If nothing at all affected the speed of light, eyeglasses wouldn't work. In fact, even gravity affects the speed of light.

 

[TheTexan]

her theory.

NASA should probably save their money.

 

[Danke]

Next NASA will say the climate is not constant.

 

[Brian4Liberty]

Man-made speed of light change.

 

[Dr.3D]

It's probably, constantly changing.

Impossible.

The metre is defined as the length of the path travelled by light in vacuum in 1/299 792 458 of a second.

Deport her.

 

[Brian4Liberty]

The speed of light is more like a recommendation, not a hard speed limit. It depends on current conditions and how it’s enforced.

Variable speed of light - https://en.wikipedia.org/wiki/Variable_speed_of_light

 

[Swordsmyth]

Impossible.

Maybe it wasn't such a good idea to define the metre that way.

 

[timosman]

Maybe it wasn't such a good idea to define the metre that way.

The goal actually was to avoid having to deal with light speed variability.

It must have been a government project.

 

[Mach]

Someone needs to tell her, light bends.

This one may be "easy" to explain.

"Things fall toward where time flows slowest". Thus, the gravity of the earth itself is enough to bend spacetime, which means our perception of time is causily distorted by earths gravity. Granted the Earth isnt as big as a black hole, where time stops, then does really weird shit as explained with Penrose Diagrams, but its gravity still affects time. If the mass of the earth were 100% constant, it may help. We get hit with debris from space constantly which can affect the measurements indirectly. This is also so minuscule that it should not even register, but on atomic clock levels of precision, it will start to rear its ugly head.

Our understanding of spacetime is so vague that we have to stretch to come up with ideas of measuring it since it is not directly observable. We also sit in the gravity well of our sun, which sits in the gravity well of our galaxy, which also sits in yet another gravity well of our neighboring galaxies. Its like trying to measure a storm of ocean waves but you cant see or interact with the waves in any direct way, only by their effects. Since the sun itself also affects our measurements of time, and considering that our orbit around the sun is elliptical, that may throw off calculations as well. For example, time flows more slowly the closer our orbit takes us to the sun, and ever so slightly more quickly the farther away we are. Had measurements been done at the same point in our orbit, the calculations may have come out the same. Trying to make those measurements at different points in our orbit should have different results.

The speed of light isnt really about the speed of light itself, but it describes the viscosity of spacetime. What is being altered is our perception by time dilation, which is quite different than the speed of light not being a constant. If it isnt, theres gonna be a whole bunch of textbooks to be thrown out the window.

I also forgot to metion the moon also does not have a perfectly circular orbit, and the closer the moon moves to us, the slower time outside of our region of spacetime will appear to flow, but for us, it will appear that time flows exactly the same. May also explain "dark matter / energy" just being in a gravity well of our own galaxy.
