The expansion of our Universe since the beginning means such gravitational waves would have very long wavelengths, outside the range of the current LIGO detectors.
But they might be heard by the planned European space-based gravitational wave observatory, LISA , or seen in future experiments measuring the cosmic microwave background.

Wait, what? Under Sciama's guidance, Hawking began thinking about the Big Bang theory: the idea that the universe began as a tiny speck that subsequently expanded.
Nowadays this is widely accepted, but at the time it was still up for debate. He developed this idea with Penrose. In the two of them published a paper showing that general relativity implies that the universe must have begun as a singularity.
By this time Hawking's disability was severe, and even walking with crutches was very difficult for him. In late , as he was getting laboriously into bed one night, he had a sudden realisation about black holes: one that would spark a series of discoveries about how they behave.
This may seem obvious. Since nothing that gets too close can escape, a black hole can only ever swallow more matter and thus gain mass. A black hole's mass in turn determines its size, measured as the radius of the event horizon, the point beyond which nothing can escape.
This boundary will creep inexorably outwards like the skin of an inflating balloon. But Hawking went further. He showed that a black hole can never be split into smaller ones — even, say, through the collision of two black holes.
Then Hawking made another intuitive leap. He argued that the event horizon's ever-expanding surface area was analogous to another quantity that, according to physics, could only grow.
That quantity was entropy, which measures the amount of disorder in a system. Atoms stacked together regularly in a crystal have low entropy, while atoms drifting around randomly in a gas have high entropy.
According to the second law of thermodynamics, the total entropy of the universe can only increase, never decrease. In other words, the universe inevitably gets more disordered as it gets older.
Hawking pointed out that these two rules of nature — the increasing surface area of a black hole and the increasing entropy of the universe — were oddly similar.
When Hawking announced his result at the end of , a young physicist named Jacob Bekenstein made a bold proposal: what if this wasn't just an analogy?
Bekenstein suggested that the surface area of a black hole's event horizon might be a measure of the black hole's entropy.
But that seemed wrong. If an object has entropy, it must also have a temperature. And if it has a temperature, then it must radiate energy, yet the whole point of a black hole is that nothing gets out.
For this reason, most physicists — including Hawking — thought Bekenstein's proposal made no sense. Even Bekenstein himself said that the black hole's apparent temperature couldn't be "real" since it leads to a paradox.
But when Hawking set out to prove Bekenstein wrong, he found that the young student was, as he later admitted, "basically correct".
In order to show this, he had to bring together two areas of physics that nobody else had managed to unify: general relativity and quantum theory.
Quantum theory is used to describe invisibly small things, like atoms and their component particles, while general relativity is used to describe matter on the cosmic scale of stars and galaxies.
The two theories seem fundamentally incompatible. General relativity assumes that space is smooth and continuous like a sheet, whereas quantum theory insists that the world and everything in it is grainy at the smallest scales, parcelled into discrete lumps.
Physicists have struggled for decades to unify the two theories — which might then point to a "theory of everything".
In his early career Hawking expressed a yearning for such a theory, but his analysis of black holes did not pretend to offer one.
Instead, his quantum analysis of black holes used a sort of patchwork of the two existing theories. According to quantum theory, allegedly empty space is in fact far from a void, because space cannot be smoothly, absolutely empty at all scales.
Instead it is alive with activity. Pairs of particles are constantly fizzing spontaneously into existence, one made of matter and the other antimatter.
One of the particles has positive energy and the other negative, so overall no new energy is being created. The two then annihilate one another so quickly that they cannot be directly detected.
As a result, they are called "virtual particles". Hawking suggested that these pairs of particles could be upgraded from virtual to real, but only if they are created right next to a black hole.
There is a chance that one of the pair will be sucked inside the event horizon, leaving its partner stranded. This severed twin may then shoot out into space.
If the negative-energy particle is absorbed by the black hole, the total energy of the black hole decreases, and therefore so does its mass.
The other particle then carries away positive energy. The end result is that the black hole radiates energy, now known as Hawking radiation, while gradually getting smaller.
In other words, Hawking had proved himself wrong: black holes can get smaller after all. This is tantamount to saying that the black hole will slowly evaporate, and that it is not truly black at all.
In Hawking conceived a radical new vision of black holes. During the Big Bang, he suggested, some lumps of matter could have collapsed into miniature black holes.
Each lump would weigh billions of tons, which sounds a lot but is far smaller than the Earth, and the resulting black hole would be smaller than an atom.
Because a black hole's temperature increases as its event horizon's surface area gets smaller, black holes this tiny would be hot: Hawking described them as "white hot".Sie durfte trotz der finanziellen Engpässe der Familie studieren und arbeitete nach dem Studium zunächst als Finanzinspektorin und später als Sekretärin.
