The many worlds interpretation of quantum mechanics says that a quantum event doesn't have a single random outcome, but rather all possible outcomes, meaning that each event splits the universe into multiple divergent universes that exist in parallel.
Space exploration and scientific experiments in space are often physically accomplished by robots rather than humans. Some scientists have suggested that in fact there is little benefit from sending humans into space at all.
The laws of physics are foundational to all of science, describing with mathematics the basic ways in which the physical world behaves. Although physics doesn't provide the simplest explanation for everything - we need fields such as biology to explain emergent phenomena like life - it does require all explanations of the world to be compatible with physics. In contrast, some religious thinkers believe that this compatibility is impossible in explaining humanistic concepts such as free will.
Do the laws of physics allow time travel? Once merely in the realm of science fiction, the possibility is now seriously considered by some theoretical physicists.
Peripheral theorists in the study of consciousness have suggested that quantum mechanical phenomena (e.g. superpositions, entanglement) may be required to explain the workings of the human mind. Skeptics suggest that there is no reason to go to a substantially lower level than a neural network for an explanation of the mind, and that neurons are orders of magnitude too large to be affected by such quantum events.
A theory of everything would unify the four fundamental forces in physics (gravitational force, strong nuclear force, weak nuclear force, electromagnetic force), and reconcile quantum mechanics with general relativity. Physicists debate whether such a theory is actually possible, though all agree that such a unified theory would be extremely complex.
The second law of thermodynamics states that entropy increases over time, or that a closed system moves from an ordered state to a random state. Critics of evolution suggest that life itself is prima facie proof that evolution is flawed, since the opposite appears to be happening - life has evolved from primordial soup to sophisticated creatures like ourselves. Defenders of evolution say that this objection is based on a misunderstanding of entropy.
Supercolliders are machines designed by physicists to accelerate particles close to the speed of light, smash them, and then observe the effects to learn more about the fundamental nature of the universe. The energy created in these collisions may be sufficiently high to create black holes.
God is the central being in Abrahamic religions, who is the creator of the universe and the ultimate arbiter of human affairs. Many philosophers have also used the word in a more abstract way, yet still in way that shares and strives to capture a sense of ultimate profundity. Atheists believe that God does not exist, for such reasons as the degree of suffering in the world, or because God is superfluous to a naturalistic universe or because the very concept of God lacks determinate meaning.
Since the industrial revolution, humans have been emitting greenhouse gases that the Intergovernmental Panel on Climate Change (IPCC) believe are responsible for Global Warming. While the majority of climatologists agree with the IPCC's conclusions, skeptics suggest that the IPCC's climate models are flawed and that recent climate changes should be attributed to natural causes.
The Catholic Church
The Church teaches that every spiritual soul is created immediately by God
Steven Novella
Does God exist? Disagree
First, to be clear I don’t believe in God or any supernatural being …
Kenneth Miller
Miller proposes that God set the world in motion and nature is evolving just as planned. "We cannot think of God as a part of nature. God is the reason for nature," he explained.
John Stewart Bell
So I believe that the many‐universes interpretation is a kind of heuristic, simplified theory, which people have done on the backs of envelopes but haven’t really thought through. When you do try to think it through it is not coherent
James Randi
Does God exist? Disagree
To make sure that my blasphemy is thoroughly expressed, I hereby state my opinion that the notion of a god is a basic superstition, that there is no evidence for the existence of any god(s), that devils, demons, angels and saints are myths, that there is no life after death, heaven nor hell, that the Pope is a dangerous, bigoted, medieval dinosaur, and that the Holy Ghost is a comic‐book character worthy of laughter and derision.
Mitt Romney
I believe that climate change is occurring — the reduction in the size of global ice caps is hard to ignore. I also believe that human activity is a contributing factor. I am uncertain how much of the warming, however, is attributable to factors out of our control.
Ron Paul
I get to my God through Christ. Christ to me, is a man of peace. He is for peace.
Eliezer Yudkowsky
I'll take bets at 99-to-1 odds against any information propagating faster than c. Note that this is not a bet for the results being methodologically flawed in any particular way, though I would indeed guess some simple flaw. It is just a bet that when the dust settles, it will not be possible to send signals at a superluminal velocity using whatever is going on - that there will be no propagation of any cause-and-effect relation at faster than lightspeed.
Robin Hanson
CO2 is clearly way up (~30%) over 150 years, and rising fast, mainly due to human emissions. CO2 is denser than its been for a half million years. ... The match between recent warming and CO2 rise details is surprisingly close, substantially raising confidence that CO2 is the main cause of recent warming. ... This adds support for mitigation. ... It was mostly skeptics bending my ear, and skeptical arguments are easier to find on the web. But for now, the other side has convinced me.
Gerard De Groot
The Shuttle story should really be titled “Lost in Space”. About $210 billion went towards a programme born of fantasy. The story came to an end because the American government finally accepted what experts realised at the beginning: strip away the drama of manned space travel, and the Shuttle is an expensive and complicated way to provide what should be a cheap and simple service.
David Evans
I am a scientist who was on the carbon gravy train, understands the evidence, was once an alarmist, but am now a skeptic. The whole idea that carbon dioxide is the main cause of the recent global warming is based on a guess that was proved false by empirical evidence during the 1990s... In science, empirical evidence always trumps theory, no matter how much you are in love with the theory.

Nothing special to say. (just trying to have enough data to see who agree with me on other subjects)

0 Points       Side Effect       21 Apr 2015     Does God exist? Neutral
yeah, God is invisible to the natural eye.

0 Points       Capricious       25 Mar 2015     Does God exist? Disagree
It's highly unlikely.

0 Points       Sherlock Holmes       23 Nov 2013     Does God exist? Agree
I beleive that God exists that loves us so that he gave His One and only Son to die on the cross for our sins and rise from the dead on the third day.I am a Christian.

0 Points       MTC       23 Feb 2013     Is global warming caused primarily by humans? Agree
The scientific consensus is clear: global warming is happening and is primarily human‐caused.

0 Points       MTC       23 Feb 2013     Should robots always be used instead of humans for space exploration? Disagree
We’ll have to expand the human race beyond just this planet eventually. Due to the “always” in the wording of the question, that alone is enough for me to disagree.

0 Points       MTC       23 Feb 2013     Is the many worlds interpretation of quantum mechanics correct? Agree
To the best of my knowledge of quantum mechanics, which is admittedly nowhere near what I’d like it to be, many worlds is the best interpretation we have.

0 Points       MTC       23 Feb 2013     Does evolution violate the second law of thermodynamics? Disagree
This idea is based entirely on a misunderstanding.

0 Points       MTC       23 Feb 2013     Does God exist? Disagree
There is simply no good evidence to suggest that any gods exist.

1 Point       Nashhinton       12 Feb 2013     Does God exist? Disagree
"God" is a delusional fantasy conjured up by our paleolithic ancestors to explain natural phenomena that couldn't be explained during the time. It was also socially constructed and popularized during the Neolithic Revolution to police the early tribes, cultures and common people through propagandized information that would appease their fears of death and misery (Terror management theory). It is the biggest cop-out ever created and has caused nothing more than technological regression and wars upon humanity.

-1 Point       Haruka       14 Apr 2012     Does God exist? Neutral
I am completely neutral. I am non-religious as well.
There is no proof that God exists.
There is also no proof that he doesn't.
Religion is just something for people to rely on, so I say believe whatever you want!

1 Point       nfoglesbee       16 Dec 2011     Can neutrinos travel faster than the speed of light? Neutral
Neutrinos may not be able to travel faster than 'c'. However, I disagree with the Yudkowsky on the ground that the sub-atomic phenomenon Einstein dubbed 'Spooky Action at a Distance' if ever harnessed would allow for simultaneous communication regardless of distance, even across the universe... hence: faster than light.
