Quotes About Universe

When you think about it, the universe is nothing but this vast knackery of churning black holes and exploding stars, constantly free atoms that collect together and become something else, and something else again.

But it is this peculiar behaviour of the gravity spring which enables the universe to have zero total energy.

the whole block of spacetime from the start of the universe to the end of the universe exists as one unchanging block. This is called the block universe model.

the fifth dimension is proposed to be circular and microscopic.

the addition of a fifth dimension has the effect of introducing the electromagnetic field in four-dimensional spacetime.

The Schwarzschild radius of the universe is the huge distance of 1.5 × 1027m (calculated from the mass of 1054kg) — a distance which is larger than the radius of the current observable universe. So the whole mass of the universe is contained within its Schwarzschild radius. This means that, for the universe as a whole, the repulsive effect becomes highly-significant. Gravity would act to expand the universe.

Why are there only three dimensions? It

As string theorist Brian Greene says in The Elegant Universe: "Another possibility, should strings fail to be the final theory, is that they are one more layer in the cosmic onion.

People like us, who believe in physics, know that the distinction between past, present, and future is only a stubbornly persistent illusion.

The message from quantum mechanics is that we should treat the universe as one connected, entangled object.

Quantum mechanics tells us that everything is connected as one object: the universe. And relativity tells us that the universe is the only thing that exists.

However, Galileo got into trouble when he turned his telescope toward a wider horizon. The discovery of the four moons orbiting Jupiter — Io, Europa, Ganymede, and Callisto — suggested that the Earth was not the centre of the universe about which all celestial bodies orbited. By challenging the geocentric model of the Solar System, Galileo found himself accused of heresy and was placed under house arrest for the rest of his life.

A time dimension is required so that energy is possible.

everything travels through spacetime at the speed of light.

Three is a natural result for the number of dimensions. It is natural because it is a number close to one. The closer to one, the better, the more in line with our expectations.

The clue to unification is the universe itself. "Uni" means "one". The universe is the one thing that exists. It is everything that exists.

the two forces of electromagnetism and the weak nuclear force were, in fact, the same force behaving in two different ways at our everyday low energies. If it is sufficiently hot enough then the electromagnetic force and the weak force would merge into a single force. This was confirmed in the 1980s in CERN, the European laboratory for particle physics, when they recreated the temperature of the early universe and demonstrated the existence of the so-called electroweak force.

Of course it does, Jomes answered earnestly. Many of life's treasures remain hidden from us simply because we never search for them. Often we do not ask the proper questions that might lead us to the answer to all our challenges. We are so caught up in fear and regret, that hope seems a foolish endeavor. Proof of hope, however, is not only possible, it is an overlooked law of the universe.

I am entirely alone. I and my shadow fill the universe.

It takes a fearless, unflinching love and deep humility to accept the universe as it is. The most effective way he knew to accomplish that, the most powerful tool at his disposal, was the scientific method, which over time winnows out deception. It can't give you absolute truth because science is a permanent revolution, always subject to revision, but it can give you successive approximations of reality.

Science has carried us to the gateway to the universe. And yet our conception of our surroundings remains the disproportionate view of the still-small child. We are spiritually and culturally paralyzed, unable to face the vastness, to embrace our lack of centrality and find out actual place in the fabric of nature.

This is one of the things I love about science. When the evidence for a slightly older universe was discovered, there were no scientists who sought to suppress it. As soon as the new data were verified, this revision in our understanding was embraced by the whole scientific community. That permanently revolutionary attitude, that openness to change, at the heart of science is what makes it so effective.

Never say no to anything, whatever the universe brings me. I've always lived by that.

The universe is an example of love. Like a tree. Like the ocean. Like my body. Like my wheelchair. I see the love.
