Something deeply hidden had to be behind things.

One possibility is: God is nothing but the power of the universe to organize itself.

It took less than an hour to make the atoms, a few hundred million years to make the stars and planets, but five billion years to make man!

There's no obvious reason to assume that the very same rare properties that allow for our existence would also provide the best overall setting to make discoveries about the world around us. We don't think this is merely coincidental. It cries out for another explanation, an explanation that... points to purpose and intelligent design in the cosmos.

Some piously record 'In the beginning God', but I say 'In the beginning hydrogen'.

It’s hard to build models of inflation that don't lead to a multiverse. It’s not impossible, so I think there’s still certainly research that needs to be done. But most models of inflation do lead to a multiverse, and evidence for inflation will be pushing us in the direction of taking [the idea of a] multiverse seriously.

Although that might seem inconsetuqntial, a 1 percent difference can be significantly big in cosmology. And the recently launched Planck observatory should be able to make spectral index measurements to at least that level of sensitivity.

The precise structure and description of the Galaxy is quite complicated with many unsolved problems. However, from the point of view of the large-scale structure of the universe, the detailed structure of the Galaxy is not very important.

When the truths are lying down with the knowledge of spiritualenlightenment. universe, cosmology, existence, darkmatter are beyond science innovation invention. -T∆NV€€®

It is irrelevant whether or not there are other forms of life in the Galaxy or in other galaxies. The fact that we are here provides an 'existence proof as it is called in mathematics. To say that we are an accident of nature is to miss the point. The laws of nature are presumably eternal and immutable. They do not change in mid-stream and suddenly acquire the ability to create a pretty toy if circumstances arise.

The study of the universe as a whole is a unique enterprise. At least in one sense one is seeking to understand the totality of things. We, as thinking beings, are as much a part of the universe as are neutron stars and white dwarfs and our destiny is inextricably bound up with that of the universe.

One of the most intriguing things about the universe, which probably cannot be explained by scientific investigations, is that it exists and we, who are a part of the universe, are able to contemplate and study it.

It is possible that those strange sentient beings of the far-future cold universe will find contemplating a warm universe such as ours not very pleasant, much as a nocturnal creature shuns daylight. But the more speculative amongst them may look back to our universe and to the Earth as an ideal world full of sunshine and a supply of adequate energy to last for billions of years, a dream world which will have passed away never to return. And what do we human beings do with this ideal dream world of ours? We oppress each other, build nuclear weapons for each other's destruction, and plunder the resources of the Earth!

If the standard model is correct, the universe started in a state of high density and temperature, with all matter and radiation forming one great continuous mass. It is very remarkable that this undifferentiated soup should have the intrinsic property that in due course of time it develops into galaxies of which at least one creates life with such staggering complexity, subtlety and diversity and often such stunning beauty. It also creates thinking and feeling beings which in turn can contemplate the universe and study its properties and which can love and hate.

One way in which a recurrence of life can occur is in the event that the cycle of the big bang and final collapse is repeated, and if galaxies are born again and again conditions for the existence of life may develop in some regions. Whether or not this can happen (assuming that the universe is closed) is, of course, not known.

Indeed, it is not clear whether it is meaningful to talk about 'after' the big crunch, just as it is not clear whether it is meaningful to talk about what happened 'before' the big bang. These questions are not necessarily meaningless, but the fact is we simply do not know.

In short, [Einstein's General Theory of Relativity] describes a colorful and amazing world where universes explode, space collapses into bottomless holes, time sags and slows near a planet, and the unbounded extensions of interstellar space ripple and sway like the surface of the sea... And all of this...was not a tale told by an idiot in a fit of lunacy or a hallucination caused by Calabria's burning Mediterranean sun and its dazzling sea. It was reality. Or better, a glimpse of reality, a little less veiled than our blurred and banal everyday view of it. A reality that seems to be made of the same stuff that our dreams are made of, but that is nevertheless more real than our clouded, quotidian dreaming.

In order to learn history right, one must listen to the right people

The more I see the sea the more I want to give myself away to its lovely current. But then I realize. I am the current. I am the sea. It is that what is me.

At the present time... we certainly do not know all the laws of nature, and it is a good bet that most of our current formulations of those laws will be revised in the future. Yet the great majority of scientists believe that a complete and final set of laws governing all physical phenomena exists, and that we are making continual progress toward discovery of those laws.
