Gravity Waves: Exploring the Lower Spectrum

In summary, the article talks about how gravity waves are not part of the electromagnetic spectrum and are a completely separate spectrum. This is due to the fact that electromagnetic radiation is made up of photons, while gravitational waves are not. Physicists are still trying to unify gravity with quantum mechanics and special/general relativity, and if a particle called the graviton is discovered, it would not be part of the electromagnetic spectrum.

I’ve read in many online articles that gravity waves open up a whole new spectrum to observe in, I’m thinking this would be down toward the lower end, below the radio part of the spectrum, is this correct?

Wat?! I've never heard anything like that. gravity waves are nothing but a traveling disturbance through spacetime. they are not an electromagnetic wave, and are no where on the em spectrum. where did you read this? maybe ur not understanding it because you wrote "whole new spectrum". I've never of any gravity wave spectrum...

DB.

Maybe I am reading it wrong, but in
this article its worded like this: Scroll down to the middle where it says "A balck hole is born"

we have explored the whole of the electromagnetic spectrum. Gravitational waves represent an entirely new spectrum.

Vast, you are reading it wrong. You are thinking "new spectrum" means "New part of electromagnetic spectrum", but the author is explicitly denying this. He is saying we know what is in every part of the electromagnetic spectrum and gravity waves aren't in there. So gravity waves must be a whole other spectrum apart from electromagnetism.

SelfAdjoint, maybe you can clear something up for me. Is anything else in physics part of another spectrum entirely?, because as far as I know, everything we observe, be it gamma rays all the way down to radio waves is part of the electromagnetic spectrum. I would think that gravitiational radiation being another physical manifestation of a celestial body, (stars, pulsars, black holes) also lie somewhere along the electromagnetic spectrum.

if only it were that easy. for the past while physicists have been trying to link QM, GR, and gravity. gravity seems to be the odd man out when it comes to either QM or SR/GR. electromagnetic radiation (i.e. em spectrum waves) are purely made up of photons, gravitational waves are not. therefore they cannot be in the same spectrum. in order to link QM,GR and gravity, physicists have came up with a hypothetical particle called the graviton, which one again, is not the same as a photon.

Ah, yes! the challenge of unifying GR with QM.

A question then: If a gravition is shown to exist in some future particle accelerator, (hopefully the LHC) will it be included in the electromagnetic spectrum?

No. Gravity is not electromagnetism.
 

FAQ: Gravity Waves: Exploring the Lower Spectrum

What are gravity waves and how are they different from other types of waves?

Gravity waves are a type of wave that propagates through a medium, such as air or water, due to the force of gravity. They are different from other types of waves, such as electromagnetic waves, because they are caused by a physical displacement or disturbance of the medium rather than by changes in electric and magnetic fields.

How is the lower spectrum of gravity waves explored?

The lower spectrum of gravity waves is explored through various methods, including satellite observations, ground-based measurements, and numerical simulations. Satellites can measure changes in the Earth's gravitational field caused by gravity waves, while ground-based instruments can detect variations in air pressure and temperature. Numerical simulations use mathematical models to study the behavior of gravity waves.

What are some potential applications of studying gravity waves in the lower spectrum?

Understanding gravity waves in the lower spectrum can have various applications, such as improving weather forecasting, studying atmospheric dynamics, and monitoring climate change. It can also provide insights into the behavior of other types of waves and their effects on our planet.

How do gravity waves affect our everyday lives?

Gravity waves play a crucial role in shaping our atmosphere and influencing weather patterns. They can also affect the propagation of sound and radio waves, leading to disruptions in communication systems. Additionally, gravity waves can impact the flight paths of aircraft, making it important to study and understand their behavior.

Are there any ongoing or planned missions to study gravity waves in the lower spectrum?

Yes, there are several ongoing and planned missions to study gravity waves in the lower spectrum. For example, the Gravity Wave Regional Experiment (GWRE) project uses ground-based instruments to study gravity waves in the lower atmosphere. The Gravity Recovery and Climate Experiment (GRACE) mission and its successor, GRACE-FO, use satellite measurements to study the Earth's gravitational field and its variations caused by gravity waves.
