Gravitational waves discovered on 100th anniversary of Einstiens theory of relitivity

When you drop something why do you think it falls?

And why is it that no matter how different two objects weigh or have different mass....as long as they are either in a vacuum or aerodynamically the same...they hit the ground at the same time?

Now why?

They are not actually in motion.

The Space-Time or DISTANCE between their original drop point and the surface of the Earth CHANGES due to Gravitational Effect or Space-Time Curvature.

They are not actually in motion.

The distance changes they do not move.

That is why when a person stands up they must fight to do so against Gravitational Space-Time Warping Effect.

This is why GRAVITY IS NOT A FORCE....it is an EFFECT.

But now this doesn't make sense.

In your example only the planet is warping spacetime/ so altering the distance.

Both the planet and the object are changing the distance between each other. All objects in the Universe attract each other.

So why doesn't the distance change to a greater extent between the planet and the object with a greater mass? Shouldn't there be an additive affect of distance adjustment in both directions?

Two cars traveling towards each other at 50 MPH hit each other at 100 MPH.

 

No wait, I've got this one. The affect of the 2 masses is a product of both masses multiplied by the gravitational constant and divided by the square of the radius.

The distance change is already calculated by the masses.

I still have the problem of not finding the link between 2 different masses being gravitationally attracted at the same rate.

 

A very good and estate question.

In reality there is a a very tiny difference.....almost impossible to detect increase in attractive force to the falling object of greater mass.

The thing is the Earth is so large it is almost impossible to measure.

Now if you start talking about Celestial Mechanics.....the differences are more noticeable.

But here is the thing....the greater the Gravity Well.....the more intent it is anchored in Space-Time.

And then to complicate things there's distance increasing because of the expansion of the Universe.

 

Correct....Dark Energy.

And without Dark Matter the stars orbiting the edges of Spiral Galaxies would be flung out into deep space as there is not enough regular matter to hold them.

How would they measure it? The measuring tools would contract too if a gravitational wave hit them.

 

Not the solid matter....just Space-Time around it.....but they would contract if not metal.

Gravity Waves hit the Earth all the time.

This is what drives the Ocean Tides...the Moon!!

It certainly doesn't rule out the graviton. I'm not sure where you're going with electromagnetism. It's matter that causes gravity and twice the matter = twice the force, no difference at that level between electric charges. They're even the same inverse square relationship.

Gravitional waves travel at the speed of light. Light travels at, well, the speed of light. Light is a wave, and it's photons. Gravity is a wave, and it's (fill in the blank).

Gravity must be quantized, otherwise if you have a particle with mass in superposition, the only way to describe the gravitational field is as being in superposition too.

 

I see the BBC's getting as much mileage out of this drivel as possible:

"Ripples arrived six years late for gravitational wager"

http://www.bbc.co.uk/news/science-environment-35560929

And the Guardian opines: 'Gravitational waves: why it's impossible not to be thrilled by this discovery'? Well I for one don't find it in the least 'thrilling'! Au contraire I find it positively boring. And to prove it - !!

https://www.theguardian.com/science...e-thrilled-by-discovery-ripples-in-space-time

'The bigger the subterfuge . . . '!

That's gravitation pull!

 

Tides and gravity waves are two different things.

 

Will time travel be possible?

Hold Up, Did We Just Crack Time Travel?
Astrophysicists famously proved Einstein’s theory on the existence of gravitational waves last week. Here’s the less covered part of it all: It might, down the line, bring us closer to moving through time.
A now-famous team of astrophysicists shocked the world Thursday after recording the gravitational waves of two black holes slamming into each other 1.3 billion light-years away.
This detection supports Einstein’s general theory of relativity in a way that revolutionizes scientific understanding of how space and time behave in extreme environments, and astrophysics will never be the same.
That includes mankind’s pursuit of time travel.

Kip Thorne of the acclaimed Laser Interferometer Gravitational-wave Observatory (LIGO) researchers deflected such assertions about his team’s finding at the press release by saying, “I don’t think [our detection of gravitational waves] is going to bring us any closer to being able to do time travel. ”
But two things are certain: Humility is essential in the path to a Nobel Prize, and other renowned astrophysicists are giving the LIGO team more credit than they give themselves.
David Spergel is a theoretical physicist and chair of Princeton University’s astronomy and astrophysics department and he’s one such admirer. Spergel concedes there is a long way to go before man comprehends the true plausibility of time travel, but he believes general relativity will be essential to that discovery, if the stars align for it.
“There are still a lot of ifs there, starting with the existence of negative mass particles and wormholes being stable,” Professor Spergel tells The Daily Beast. “But general relativity’s equations—which gave us black holes, and we see very strong evidence for them with LIGO—are telling us that that would permit time travel.”
Whether or not they want to claim it, the LIGO researchers just made great strides toward understanding time travel.

Einstein’s general relativity explains gravity and how things move through space, and leading time-travel theories in the scientific community must account for it.
Einstein explains gravity as the product of mass manipulating the fabric of space-time. This fabric is known as “space-time” because the two concepts are inseparably woven together throughout the universe, much in the same way that a mile is roughly six minutes away from a good runner.
Like a bowling ball sitting amid a trampoline, black holes are massive objects that warp the fabric of space-time. Anything (say, a golf ball) that approaches a black hole (the bowling ball) gets faster the closer it gets because that is where the fabric of space-time (the trampoline) is most warped.
This warping is caused by any and everything with mass, but is especially intense around the greatest objects in the universe: black holes. And that’s where the magic happens.
“Time travel might be possible in situations that involve these very strong gravitational fields,” another Princeton astrophysicist, Edwin Turner, tells The Daily Beast. “You would only get time travel in the strong-field gravity.”

 

Yes, one's to do with the phases of seas and oceans, and the other's to do with ups and downs. Duh!

 

UHHH....no.

If Gravitons existed you would need 2 times as many Gravitons to place an object of 2 times the mass of the other in a fall at the same rate.

If you look at the night sky you may see a star and since that star is hudreds if not thousands of light years away, it means that that's how long it took light to reach us.

So when we look into the night sky, we are literally looking into thousands, millions of years in the future.

What happens if we can traverse the gap instantly?

Will we be a thousand or a million years in the past, near a star as it was when you looked at it?

What happens if we instantly traverse the distance and end up back on earth? Since it's "instant" will we be now thousands or millions of years in the past now?

If here on earth is now, then a star would be thousands of years in the past.

In a quantum world, everything exists all at once at all times

 

Gravity does not push or pull...only a FORCE can do that.

Gravity is an EFFECT of warping our Universal Space-Time.

AA

 

You're totally confused. Why wouldn't there be 2 times as many gravitons?

 

Any push or pull results in acceleration. Any acceleration results in curved (or as you want to say "warped") coordinates, including the apparent (relative) bending of light. We don't need gravity to "bend" light, any acceleration will do.

Gravity is an acceleration field that can be described by curved space-time coordinates. Gravity never pushes, but it certainly does pull. That's why we don't fly off the Earth.

 

Oh, so it isn't just about 'up' and 'down' then. Obviously there's more to this gravity lark than I thought - AboveAlpha has spoken.

'Universal Space-Time' Hmm, well it sounds impressive enough - even more impressive if followed by 'Continuum'.

 

The binary pulsar used to confirm the existence of gravitational waves more recently...was actually discovered in 1974. Basically two extremely heavy stars in orbit around each other. It's been monitored now, for going on 40 years as this type of system had been predicted to radiate gravitational waves.

Some credit is due to the astro-physicists who discovered this binary pulsar. Without something definitive to be measured, there would be no point to a measurement. In 1993, the Nobel Prize in Physics was awarded to Russell Hulse and Joseph Taylor of Princeton University for their 1974 discovery

Regarding gravitational waves, this was noted many years ago in a published paper in Scientific American "Gravitational Waves from an Orbiting Pulsar", Weisberg, J.M., Taylor, J.H. and Fowler, L.A., 1981, Scientific American Oct, 74.

As Newton so aptly stated,

 

The orbital period of the binary pulsars decrease, indicating they are losing energy via gravitational waves. They are indirect evidence of gravitational waves. This newest measurement at LIGO stations is direct evidence.

 

I never stated otherwise.

Wanted to acknowledge the discovery...40 years earlier, which provided the source for which this most recent measurement was conducted on.

Here's an article appearing in Scientific American in 1981.
https://83140fcfaa1a262417b2f1f7173...ktQ1Jic1U/Library/For_Stat/Weisberg_J_M_1.pdf

This same binary system was used to detect a direct measurement of gravitational waves.

As I've said...knowledge is built upon knowledge obtained by others. This most recent discovery wasn't about aiming at a point in the sky and hoping for the best. This binary system had been monitored for over 40 years as a test bed for gravitational waves. The technology finally caught up to the theory to actually measure gravitational waves.

 

First, I'm just a nail bender trying to understand something I probably have no understanding of at all, yet here I go. I'm still not sure if gravity is pushing me down or pulling me down either way it sucks. I think it's cool that so many are trying to figure it out. Heres my thinking which may be the most ignorant stuff you've read yet. Here's my question; given the whole equal and opposite thing is it possible that what why call dark energy is the opposite of gravity? Say if there where gravitons wouldn't we also be able to postulate the existence of lets call them repulsions?

 

Phobos or Deimos are equally decreasing their orbital period and getting closer to Mars and one day will collide with it. Other frictional factors than gravitational waves seem at work here. Tidal forces, atmospheric friction etc.

 

Not in the case of the PSR B1913+16. The decay is exactly in accordance with gravitational wave radiation. Not all orbital decay is due to gravitational waves, simply a loss in angular momentum is sufficient (that's how our spacecraft come home). I know the orbit of Phobos is decaying due to gravitational pull (tidal forces) and will either break apart or collide with Mars, in millions of years. Deimos is much further away and the orbit is not decaying but increasing. Millions of years from now, Deimos will most likely leave Mars orbit.
