The
gravitational
pull of things was a lot stronger near the Big Bang.
Because if there had been, they would have collapsed under the
gravitational
pull into a huge black hole.
Individuals with material that could help us were drawn toward us by some kind of
gravitational
force.
But as that space shuttle returns to Earth, and as the astronauts enter the Earth's
gravitational
field, they begin to see the effects of gravity.
And as they land, they're fully aligned in the
gravitational
field.
We're, of course, all stuck in the Earth's
gravitational
field right now.
That, much as the
gravitational
pull of the Earth slows the ascent of an apple tossed upward, the
gravitational
pull of each galaxy on every other must be slowing the expansion of space.
Is that absolute, like force and mass and
gravitational
attraction?
What they found on Monday was evidence of the ringing of the space-time of the early universe, what we call
gravitational
waves from the fundamental era, and here's how they found it.
Those
gravitational
waves in the structure of space are totally invisible for all practical purposes.
But early on, when the universe was making that last afterglow, the
gravitational
waves put little twists in the structure of the light that we see.
Their extreme sensitivity makes them candidates to be used to detect
gravitational
waves in future space-based detectors.
And so, I abandoned my dream life for a single room on the backstreets of Kyoto, Japan, which was the place that had long exerted a strong, really mysterious
gravitational
pull on me.
At the beginning of the week, we got the exciting information that the theory of inflation, which predicts a big, infinite, messy, arbitrary, pointless reality, it's like a big frothing champagne coming out of a bottle endlessly, a vast universe, mostly a wasteland with little pockets of charm and order and peace, this has been confirmed, this inflationary scenario, by the observations made by radio telescopes in Antarctica that looked at the signature of the
gravitational
waves from just before the Big Bang.
You use
gravitational
flybys, slingshots, where you pass by a planet at very low altitude, a few thousand kilometers, and then you get the velocity of that planet around the sun for free.
It involves
gravitational
waves.
Nothing, not even light, can move fast enough to escape a black hole’s
gravitational
pull once it passes a certain boundary, known as the event horizon.
When matter approaches a black hole, the immense
gravitational
field accelerates it to high speed.
And for objects too far away to be sucked in, the massive
gravitational
force still affects their orbits.
Similarly, light that passes close enough to an event horizon will be deflected in a phenomenon known as
gravitational
lensing.
Although because their
gravitational
fields can affect a planet from a large distance, they could be dangerous even without a direct collision.
In fact, the only way we can detect this dark matter is through this
gravitational
interaction, how things orbit around it and how it bends light as it curves the space around it.
We say that it has a
gravitational
pressure, which ordinary matter and dark matter do not.
Although tsunamis are commonly known as tidal waves, they're actually unrelated to the tidal activity caused by the
gravitational
forces of the Sun and Moon.
The enormous
gravitational
pressure of so much material compresses and triggers nuclear fusion in the star's core.
All that energy was pumped into the fabric of space and time itself, making the Universe explode in
gravitational
waves.
And on September 14 of 2015, just days after the detector had gone live, the
gravitational
waves from those colliding black holes passed through the Earth.
Allan Adams: So that's my very good friend and collaborator, Scott Hughes, a theoretical physicist at MIT, who has been studying
gravitational
waves from black holes and the signals that they could impart on observatories like LIGO, for the past 23 years.
So let me take a moment to tell you what I mean by a
gravitational
wave.
A
gravitational
wave is a ripple in the shape of space and time.
