“I just think too many nice things have happened in string theory for it to be all wrong. Humans do not understand it very well, but I just don’t believe there is a big cosmic conspiracy that created this incredible thing that has nothing to do with the real world.” -Edward Witten You don’t have…

“The law of the conservation of momentum is the basis of the static thrust equation, the law of the conservation of energy is the basis of the dynamic thrust equation. Provided these two fundamental laws of physics are satisfied, there is no reason why the forces inside the resonator should sum to zero.” -Roger Shawyer,…

“As far as the laws of mathematics refer to reality, they are not certain; and as far as they are certain, they do not refer to reality.” -Albert Einstein If you create an entangled pair of particles, and stretch them apart as far as you want, the entanglement remains. If you make a measurement of…

“We are actually living in a million parallel realities every single minute.” -Marina Abramovic Ever since quantum mechanics first came along, we’ve recognized how tenuous our perception of reality is, and how — in many ways — what we perceive is just a very small subset of what’s going on at the quantum level in…

“If you want your boomerang to come back, first you’ve got to throw it.” -Steven Hall If you take all the matter out of the Universe, all you’d have left to warm you would be the radiation from the Big Bang’s leftover glow: the cosmic microwave background. At just 2.7º C above absolute zero, there’s…

“The whole edifice of modern physics is built up on the fundamental hypothesis of the atomic or molecular constitution of matter.” -C. V. Raman As far as humans have figured out, there are four fundamental forces in the Universe: the three of the Standard Model (electromagnetism, the weak and strong nuclear forces) and General Relativity,…

“To raise new questions, new possibilities, to regard old problems from a new angle, requires creative imagination and marks real advance in science.” -Albert Einstein When we first began looking for exoplanets, we were expecting that other solar systems would be like ours: with inner, small, rocky worlds and outer, large gas giants. What we…

“Two things are infinite, the universe and human stupidity, and I am not yet completely sure about the universe.” -Frederick S. Perls, quoting Einstein The Universe we can see and access is certainly a big place. We see that it goes on for 46 billion light years in all directions, full of stars, galaxies, matter…

“The Universe is very, very big. It also loves a paradox. For example, it has some extremely strict rules. Rule number one: Nothing lasts forever. Not you or your family or your house or your planet or the sun. It is an absolute rule. Therefore when someone says that their love will never die, it…

“Cosmology is the study of the origin, evolution, and fate of objects in the observable universe. […] The key to the birth and evolution of such objects lies in the primordial ripples observed through light shining through from the early universe.” -Wayne Hu The Big Bang’s leftover glow — the cosmic microwave background (CMB) — is…
