And I know they could be testing me
The data might be wrong
A preplanned concocted recipe
And played up all along
But at least my graphs are beautiful
With sigma 5.1
This I know
This I know

They told me don't worry about it
Analyze the chirp and
No more
They told me be careful
And doubt it
But I've seen a merger
Of black hole-ole-ole-oles!

LIGO feels when space is rippling through
With a wave of
Gravitation

LIGO feels when space is rippling due
To a tensor
Perturbation

Vacuum sealed interferometer
An L 5-mile long
Split a laser, bounce 300 times
Compare the distance gone
One built in Louisiana and one more in Washington
That's LIGO
Yeah LIGO

A Billion lightyear journey
To cover
Then it hit the Fabry-Perot
Lengthening one leg then
The other
Making fringes dance on
The dio- o- o- ode!

LIGO feels when space is rippling through
With a wave of
Gravitation

LIGO feels when space is rippling due
To a tensor
Perturbation

LIGO feels that space is rippling through
From an ancient
Amalgamation

LIGO feels that space because it's crew
Gave it seismic
Isolation

This event's power is
Enormous
Fifty universes
Of suns
We had indirect clues
Before this
All you GR haters
You were wrong -ong -ong

LIGO feels when space is rippling through
With a wave of
Gravitation

LIGO feels when space is rippling due
To a tensor
Perturbation

LIGO feels that space is rippling through
Can you feel the
Excitation?

LIGO's view of space is rippling through
Our collective
Imagination

@BoneRemake, @packo. I think people often make the mistake of thinking that the universe started as a bunch of energy/matter suspended and then exploding into an existing, infinite 3D space; but that is not the theory. It seems to me like the video that @packo linked to is partially suffering from this error--especially when it shows the universe as floating and expanding into a sea of "outside" stars (but it gets many things right--I am still glad you posted it, thanks). As I understand it, the big bang is meant to have *created* the dimensions (including time) and it is the dimensions themselves that are expanding, possibly "into" a higher dimensional space that we are not equipped to perceive.

The usual metaphor (presented by Steven Hawking, among others) is to think of the 2-dimenstional surface of a balloon as it inflates. 2D beings trapped on the surface of the balloon would observe that all points on the expanding surface are moving away from each other, but such people would be incapable of imagining into what, since they have no intuitive understanding of a third dimensions. The balloon also illustrates the concept of "finite yet unbound." The 2D balloon-surface citizen could travel forever in one direction on the surface and never find the boundary; instead he just goes eternally round and round on the balloon which, never the less, still has a finite area even though the border remains imperceptible to the 2d resident. It is possible that the universe is a 3d version of this.

Because it is space itself that is expanding (not matter expanding into existing space), the speed at which two objects "move" away from each other increases in relation to how much expanding space their is between the two objects. In reality, the objects are not moving apart as we normally think of it--space itself is just getting bigger in between them. This means that regardless of where you are in the universe, it will look like you are at the center of a huge explosion with everything else rushing away.

All points (and all space) in the universe were once at exactly the same place, a single point, which means that all points in the universe began in the center and, in a sense, still are at the center from their own perspective. At large distances, this speed adds up until it exceeds that of light, which means we will never see or visit objects that are currently more than X light years away; and the value of X is shrinking so that, in fact, the entire universe will eventually fall behind a relativistic curtain until all the galaxies and even stars disappear eternally from each others' view, with space filling in faster than light can catch up. This does not violate relativity, again because the objects are not actually moving faster than light, there is just a huge area of space growing between them.

I am less sure about this, but I think even the space between the atoms and subatomic particles might take on properties (such as an expanded Plank length) that eventually prevent such particles from getting close enough together for the electromagnetic/strong/weak/gravitational forces to function and that's the end of chemistry.

about 3:35 is where it gives answers
sorry about the long intro before anything starts

I know!!! I mean this is a multi billion dollar device that's suppose to be carrying some of the riches people in earth up for a view from space. People have prepaid in the hundred's of thousands for a 15 minute trip.

Shouldn't this be built by robots with superior brains or something?

I mean it shouldn't look like it's a bunch of college students in the garage doing this no?

I think if you look at the NARPA Races, those college students look more professional than these guys ????

A YouTube user-produced and submitted video that seems to be an effort to literalize (that a word?) and extrapolate into 3 dimensions a view of space-time that is often used to demonstrate the concept of space-time and gravity's interaction with it (the ol' bowling ball on a trampoline). I'm not quite sure what he was trying to show (and I watched his other, similar video on the same topic), if anything. The ultimate conclusion he seems to arrive at is that space-time warps around planets in a spherical shape (????) Or... something. I guess.

Deathcow, I think he was just trying to visualize space-time in 3 dimensions, rather than the trampoline model we've all seen. I don't think he meant it as a serious scientific explanation. More thinking out loud (but in a video). I read his other posts and he didn't exactly come across as a hard-core sci.physics.relativity type. I'm not either, but I dig this type of stuff. This video just doesn't have any information, or even anything interesting or scientifically correct, imho.
