A Tapestry of Gravity: LISA and the Future of Gravitational Wave Astronomy

Shane L. Larson, Northwestern University
Nearly everything we know about the universe has been discovered using photons - light in all its myriad forms. However, using advanced technology we can now access the cosmos through the detection of ripples in the fabric of spacetime itself: gravitational waves.
Dr. Larson will explore the modern description of gravity, how we can measure gravitational waves, and what we expect to learn. He will focus on LISA, the space gravitational wave observatory being launched in the early 2030s by ESA and NASA. LISA observations will unveil the adventures of black holes of all sizes, neutron stars, and white dwarfs as they interact, merge, and send ripples across the universe. Join us to explore these discoveries - because gravity has quite a story to tell.

Fantastic, thank you for sharing. Excellent delivery from Professor Larson, I was curious to know how LISA would "focus" on a particular target, interesting.

[@davidswift9120]

Many thanks for this fellas. Really enjoyed the talk.

[@hpmmiggie]

Thanks for the update on LISA. Ive been reading about it for quite a few years so it's nice to see some positive news on the project.

[@paulwary]

To be fair to the PHANGS project, you can see why they went the extra mile for the acronym. 😅

[@alfredtetzlaf9163]

thank you!

There is no gravity. Earth's magnetic field controls quantum magnetic fields called bonding force of unification of unidirectional flow. Pressure of magnetic bonding. Mass is an outward force of pressure. If gravity exists, you should be able to walk up walls of massive buildings or mountains. That doesn't happen because magnetism bonding is forced redirected current. Internal magnetic fields center of force flow. Our mass is repelled towards the greater magnetic field as unification of the unidirectional flow of magnetism. Heat waves are throughout space, not gravitational waves. Pressure is heat propulsion from cold repulsion into cold repulsion. Magnetic fields are cold repulsion to heat propulsion from cold repulsion cycling circulation patterns as mass in quantum magnetic fields of forced pressure cycling circulation. Theoretically factual. Probability that works with quantum physics without gravity. Friction causes sparks of striking heat in magnetic fields of forced renewable energy as sparks (electrons) of light. Light is only present in resistance to mass. Heat striking mass sparks light like a filament through the atmosphere towards grounding or bonding force in magnetic fields. Factually, probability works with quantum physics without gravity. Magnetism is synchronization of the flow of force of expansion. Heat passes through all mass in its path until resistance is overcome by open space itself and returns to dark heat energy outside of entanglement of mass. Factual probability that works with quantum physics without gravity. Gravity doesn't exist. Electrons are sparks of striking magnetic fields like static electricity. Current of flow as heat exchanging energy in atoms. Hydrogen has the strongest magnetic field of the elements. As elements expand, their magnetic fields weaken.

hm... thats an Interesting take. I look forward to your published paper on arXiv :)

[@Deathadder90]

Didn't get very far through the flat earthy wall of text there. But did want to respond to one interesting sentence that I managed to reach: "If gravity exists, you should be able to walk up walls of massive buildings or mountains." We should? According to who and to what calculation? Have you done any calculations yourself or do you just paste whatever copypasta you've been sitting on?

[@hpmmiggie]

@@Deathadder90 Im suspecting that pasta (and koolaid) is ChatGPT

[@MotoMystery]

What drugs do you use? I want the same with 100euros

[@seriousmaran9414]

​@@Deathadder90it does not include the extremely low effect of gravity and the effect of a wall compared to the earth. In reality the effect of the wall is so small compared to the planet you would get instantly pulled off. So this is obviously incorrect.
