'Bent time' tips pulsar out of view

Interesting. Since space is what’s between objects, (space is not an object) it’s difficult to see how space can be bent.

The one thing I need to know about physics that makes it amazing:

There is so little actual material in the universe to mean it is made out of nothing.

Exactly. It can be bent only if it is made of what used to be called “The ether”. Which is two parts hydrogen and one part vanilla pudding.

Its the Gravity field that is bent by the mass of an object sitting in space-time. The same effect that hold our little rock in orbit around the Sun.
The bending of the space-time /Gravity field causes light to change direction, like canoe across a whirlpool, you think you've taken a straight line but in reality you've moved sideways.

Actually, I wish I hadn't thrown it away.

Did you get one of those Joe Louis-endorsed pieces of plastic that allowed a flick of the wrist to turn the LEDs on?

Or did you have to employ the Arthur Dent method of using the other hand?

[The Cajun]

The pair circle each other in just four hours - the second fastest such orbit ever seen - and the pulsar spins seven times per second,

Those two suckers have it "hooked up" pretty good, cosmologically speaking :)

They’re just making sweet music together, Dancing in the Moon light.

Totally

Each is approximately 1.3 times heavier than our Sun, but they are only separated by about one solar diameter.“

That's the amazing thing to me.
That much mass moving at that speed, almost seems they would rip each other apart from gravitational fields alone.

Their surfaces have to be very physically warped and constantly changing.

[Calvin Locke]

Hmmm, a point on the pulsar’s equator travels then @ ...10mi diameter x pi x 7 rotations/sec * 3600 secs = 791,280 mph.

Compare to Earth’s 1000 mph, or the Moon’s paltry 10 mph.

[outofsalt]

Well, I’m sitting here posting in my robe, if that tells you anything...

[moose07]

I would imagine that they are seriously entwined, possibly on the verge of becoming a single entity.

[The Cajun]

Have to wonder what would be the results of that merger.

The normal star blowing up, the neutron star gaining mass, a combination of both, etc.

[moose07]

It really hurts the mind,doesn't it.
Centrifugal force is trying to rip it apart and gravity is holding it together. Ouch.

[moose07]

The Pulsar will probably start gaining material conveyerbelt style from the other star, and slowly absorb it.
Possibly. :)

Darks will make the strongest coffee ever tasted using the pulsing energy of that star ...

[MHGinTN]

Space is filled with the zero-point field of energy, so technically it is ‘something’.
