The concept of NEUTRON STARS - of all things - being "squishy" boggles my mind as much as learning that a teaspoon of neutron star would weigh like 10 million tons.

Also, how counter-intuitive is it to hear something as compact as a neutron star be described as 'squishy', but that black holes which are essentially extreme gravitational wells in spacetime, be described as being ' hard ', and not deforming under these extreme conditions. Mindblowing stuff.

<a href="#" class="seekto" data-time="1934">32:14</a> One of my puppies did that tonight, but he also snapped his leash. So, naturally, I'm wondering whether or not spacetime or its fields could snap from the tension on them? Would they form new loops of the string, vibrating at new relative frequencies and so as different particles?

Roger Penrose suggested that in our universe there could be Gravitational Waves from Black holes coming from a previous universe in the very far past. If such a previous universe Existed and if Black hole morgens emitted gravitational waves: could these waves be measured with the Neutron Star method? Or would such waves Still be beyond our reach and not a Potential source?

Why only two arms for LIGO? Wouldn't a “3D mesh” of arms give us much better detail? Surely we could separate out the direction and magnitude of the waves with an array of detectors.

@phillipcoetzer8186 11 месяцев назад
As a layman in this area ... I understand that two orbiting masses should spin arround each other forever ... but they loose velocity and collide and one way they loose that energy is by dispersing gravitational waves. Is this correct? If so it then implies that energy is required to change the state of gravity. It also implies that there's a direct similarity between electromagnetic waves and gravitational waves. It's just at a different scale.

The evolution of dark matter and matter looks so much like how our brain’s neural network forms does it not? Isn’t that remarkable? I just find it so beautifully ironic, almost as it is intended. Patterns like this are everywhere in nature. The universe is no exception. What a wonderful time to be able to discover these things … we are the pioneers for future generations.

The moment a particle is a wave; it has to be a conscious wave! Gravity is the conscious attraction among waves to create the illusion of particles, and our experience-able Universe. Max Planck states: "Consciousness is fundamental and matter is derived from Consciousness". Life is the Infinite Consciousness, experiencing the Infinite Possibilities, Infinitely. We are "It", experiencing our infinite possibilities in our finite moment. Our job is to make it interesting!

... or at the _very_ least we start looking/thinking in these other ways, or directions. ive become more and more disappointed over the last 20...30 'odd years because of the unwillingness to even think in these... other ways. admittedly its taken me most of that same time to open up to them, I was very 'science only/has all the answers' based and unwilling to examine these "so called" fringes but, if honest they are just other ideas /points of view and in many cases being thought of, or believed in for much longer. i sometimes wonder if this build up of "dark matter /energy" (2 other words for... we don't know) is the 'manifestation' of the enormous amount of information we have generated in the last few hundred years painted onto higher dimensional 'shaped' objects that we can only see/interact with the equivalent of a shadow, or reflection of our 'every day' objects a reflection/shadow of something having vast amounts of near massless, but seemingly correct information about the objects but only when viewed in a very certain way like slices of the 3d object does when viewing in flatland/lower dimensions... I hope that makes some sense 😊

So gravitational waves are not effected by time dilation? When two BHs are merged, time is slowed down relative to the earth. Like a movie "Interstellar", one hour on the planet next the BH was 7 years on the earth relatively. So say it took 2 seconds at the last moment of the merge and we here on Earth detected it. It's still the same 2 seconds? No time delation? Would that mean there's no "red-shift' because of the expansion of the universe, spacetime?

I've been posting this story for a while, now. Is it possible it's related to gravitational waves? Time is fascinating. I worked the subway stations for nearly 10 years. From one end of the city to the other. Every so often I would notice the city would be saying that, "Today just flew by" or "The day was just dragging along." How can an entire city, with no interaction with each other until they used the subway, complain about the same time paradox unless it was effected by it? Maybe a time distorted bubble the earth passes through in its revolution around the sun. Maybe random waves of time distortion hitting the earth? Maybe they're given off by the sun. Maybe they're from outside our Terran system and reach us in intervals. ???? Ti-i-i-ime, is on my side. Yes, it is! If you can think of a better way to do a blind survey of an entire city, in the small window of opportunity, I'm all in. Until then, I invite you to spend a couple years in the subways, during rush hour and you'll see for yourself. Just listen as an entire city gets off of work and gets out of school. You'll see it's more than a, "coincidence of circumstances."
@2Worlds_and_InBetween
