What do we know about gravitational waves?

 

Gravitational waves travel at the speed of light and pass through everything like they don’t exist and are basically nothing but a type of radiation that’s capable of changing space and time, but not mass. When I’ve had my interferometer out in the good ole days, along with a computer, cameras and other equipment I made many great scientific discoveries concerning gravitational waves.

There are at least two different types of gravitational wave sources. There are sources that send out a single gravitational wave, and there are sources that send out multiple gravitational waves. For a single gravitational wave, you don’t have to do much with the equipment, but with a multiple gravitational wave source you have to move all of it from place to place in order to get maximum data… and there’s tremendous amounts of data that can be gathered from a source that’s sending out multiple gravitational waves.

Gravitational Waves can be some of the most interesting things that you’ll ever get to observe with an interferometer, computer, cameras and other equipment. Gravitational Waves aren’t those boring things that LIGO and VIRGO show us; gravitational waves are extremely interesting when you use all of that equipment properly. Especially when you find spacetime first, in order to set everything to ZERO.

The cool thing is that you and I can track down where gravitational waves are coming from here on Earth by moving all of this equipment from one location to another. If you want to track down closer gravitational waves that are throwing out gravitational waves only minutes apart… all day and all night long… and they usually exist within 100 miles or so from your location… you shouldn’t be sloppy in doing so, you should keep your tracking equipment sealed up at all times.

Being sloppy can endanger your life in more than one way when tracking down gravitational waves. When I was much younger and had discovered how to track down gravitational waves in 1995 to their sources here on Earth, I was very sloppy. Back then I had no idea that others could become dangerous out in the field towards me. If you ever decide to track down gravitational waves in the future, don’t tell anyone, or your life will be in danger; great danger if you succeed in tracking down gravitational waves to their source, especially if the sources are future earthquakes and or “slow earthquakes”. So, you have the human factor to watch out for, don’t trust them when out tracking down earthquakes before they strike, if the earthquakes are sending out multiple gravitational waves.

Then there is the fact that you are a beginner, and don’t know better, just as I was decades ago. Keep all of your equipment sealed up and keep a list so that you don’t leave any of it behind when out tracking down where gravitational waves are coming from. Check your list when you get ready to leave an area that you just checked for gravitational waves. Tracking gravitational waves to their source when earthquake activity is the source means that you should start out with plenty of gas in the tank of your vehicle and that you should pack food and drinks to eat and drink along the way. Make sure you carry an ATLAS of the state you are in, and plenty of paper for hard copy, something could happen to your laptop, and you can lose your data.

Don’t be sloppy out in the field, keep everything sealed up tight. You are messing with gravitational waves, even though they don’t move matter when passing through, they move “spacetime”, spacetime distortions detected by the interferometer are what alerts your computer that something is occurring and how much it’s occurring over space and time.

Now that you know how to detect distortions in spacetime, if you are sloppy you are going to have to watch what you do in the future at or near this location. If you weren’t sloppy, you have nothing to worry about at or near this location in the future. Think about it, with that equipment “distortions in spacetime are located and taking place”. It’s not the distortion of “space” that you have to be worried about, it's the “distortion of time” that you should be worried about.

What do you think can’t possibly happen when a distortion in time is discovered? That’s right, “time” is displaced either into the future or into the past. You need to discover the past and the future with that same equipment, because both exist along with the present, and if you are there detecting distortions in spacetime, well then, the distortion was either of the past, or of the future. Even though you didn’t see anything, or hear anything at the time, it's when you come back at a later date, that something else can be waiting there for you, and it’s not your friend. Tracking down a multiple gravitational wave source can end your life if you seriously aren’t watching what’s going on around that location when you come back in the future. At one point in time or another, something is going to be waiting there for you, because you split the spacetime continuum or at least opened a doorway.

So… what I know about gravitational waves, is that they are easy to detect with an interferometer, computer, cameras and other equipment… and that your life will definitely be in danger out in the field if you are tracking down a gravitational wave source that’s sending out “multiple gravitational waves” that’s possibly up to around 130 miles away or less on average. Yes… it's very fun to track down gravitational waves that are coming from a source that’s emitting multiple gravitational waves here on Earth, but once people see all of that equipment, they sometimes become dangerous; stay away from people when traveling with all of that equipment. Be on the lookout for critters at all times.

Why does everything possess gravitational field?

 Everything which possess mass possess gravitational field.

English mathematician and physicist Issac Newton discovered gravity when he saw a falling apple while thinking about the forces of nature.

So, the apple actually didn’t fall on his head !

Humans only recently (like in last 300 years) realized what gravity is all about.

Then came Einstein !

The general theory of relativity says “ gravity arises from the warping of space and time. “

When i first read that, i didn’t have an idea what does it even mean.

I just knew some facts like—

• Light bends when passing near massive objects like sun.
• The clock raised above the earth speeds up relative to a clock on earth’s surface.

I was like “spacenet may be responsible for that.”

This is spacenet.

So, finally after two days of restlessness, I remebered what faded away.

So yes, everything which possess mass possess gravitational force, but why?

It is the “space-time”, which i used to call “ space-net” or “imaginary net.”

The universe is full of this Net and its not 2D net, its 3D, so it is present in every corner of space.

Now,

How gravity is formed→

1. Let a space net be like volleyball net.

Like this→

Note- its not 2-D ,its 3D and it is imaginary.

2. Place the earth which has appreciable mass on this net.

(Never thought i would use ms- paint in my life)

So, the earth applies force opposite to its curved surface area on the space net.

3. Now,

Newton’s third law of motion, “ every action has its equal and opposite reaction”

So, same force is exerted on the earth by the net→

This reaction force is “gravity” which applies on all objects on earth surface towards the centre of earth.

Thanks to Albert Einstien !

ILLUSTRATION→

Suppose on the back seat of a car, there are four person sitting and there is no space left.

Somehow, I popped in the car trying to adjust, and somehow, i managed to secure my space.

But, it is very uneasy over there because i apply force on other four people and in turn they also apply a force on me.

Now, consider, those four person are space net and i am some object trying to fit in between those, so i experience force, which in case of earth is “Gravity”.

What do gravitational waves tell us?

Announced today, the identification of a new type of gravitational waves using the whole Milky Way Galaxy as a detector will redefine our knowledge of the Universe and might lead to the detection of the mysterious cosmic strings. They could also further our understanding of the supermassive black holes

The instruments with which we researched gravitational waves for many years, like LIGO, are only 4 km long. Today’s announcement detected them using pulsars that are thousands of light-years apart, and this way, much longer wavelengths could be identified. It’s almost like using the whole Milky Way Galaxy as the gravitational waves detector, but the frequency it is sensitive to is on the scale of years or even decades. This meant that collected data from decades had to be used to find these signals, and it had to take so long; years or decades had to pass for just one wave to get through such a detector.

Supermassive black holes reside in the centers of galaxies and can be millions or even billions of times more massive than the Sun. They might merge when galaxies collide, and before that, they revolve around their common center of mass, the barycenter; they then should steadily produce gravitational waves of such long wavelengths. This mode of detecting them is not sensitive enough yet to point to individual sources, but instead, it catches many gravitational waves background hum that permeates the whole space.

Supermassive black holes are not the only candidates for producing these waves. The others are cosmic strings, one-dimensional topological defects in spacetime that originate just after the Big Bang. They are similar to cracks in ice which form during the phase transition from liquid water to a solid. If they exist, they would be like particles, but instead of being point-like, they would be stretched across the Universe and string-like. They would sometimes collide, which would cause loops in them to form, which could occasionally pinch and release gravitational waves.

With more extended observations of data from pulsars, the original individual sources of these long gravitational waves should be identified and point to supermassive black holes. However, if the sources cannot be singled out and we still get just constant hum, it will mean that it originates from cosmic strings; it would then need to lead to new physics. Because the idea of their existence is somewhat flamboyant, the leading theory of where the long gravitational waves come from is supermassive black holes.

We are currently unsure if they can merge, and they might rotate around their barycenter forever when they are around three light-years apart. This would mean that supermassive black holes in the centers of galaxies exist in multiples and not as a single huge one.
