This was the first direct measurement of gravitational waves ever, as predicted by Einstein.
Physicists finds evidence from just after the Big Bang that supports the controversial holographic universe theory.
The speed of light is a universal constant, but that doesn’t necessarily mean that light always travels at that speed, does it? “There was a young lady named Bright,Whose speed was […]
The times in history when science was deadly and dangerous.
Never heard of SKA, the square kilometer array? Once it starts taking data, you’ll never forget it. “Not all chemicals are bad. Without chemicals such as hydrogen and oxygen, for […]
The smart money is still on LIGO, but there sure looks like something funny is happening if the new group is correct. This article was contributed by Sabine Hossenfelder. Sabine […]
The atoms, planets, stars, and even galaxies aren’t expanding, even though space is. How come? This article was written by Sabine Hossenfelder. Sabine is a theoretical physicist specialized in quantum gravity […]
There’s useful science to be gotten out of it, but most science that mentions it is anything but. “There is a voice inside of youThat whispers all day long,‘I feel this […]
And even with them all in place, what do we still not know? “The joy of life consists in the exercise of one’s energies, continual growth, constant change, the enjoyment of […]
And just what did come before — way before — the Big Bang? “We are part of the universe that has developed a remarkable ability: We can hold an image of the world in our […]
The latest challenger to dark matter’s throne may not be so difficult to knock off, after all. This post was written by Sabine Hossenfelder. Sabine is a theoretical physicist specialized in […]
Physicists create a structure that breaks the symmetry of time.
Cognitive scientist Donald H. Hoffman asserts that not only do we invent our own personal views of reality, it’s an evolutionary necessity.
Physicists propose that violations of a fundamental law of physics in early stages of the universe are responsible for the mysterious dark energy.
If you were betting on LIGO, you bet wrong. Just like everybody else. “‘Topology is destiny,’ he said, and put the drawers on. One leg at a time.” –Neal Stephenson One […]
Want the speed of light, the fine-structure constant or others to change? There’s a new obstacle to overcome. “The mystery about α is actually a double mystery. The first mystery — the […]
And if it were, is there any way we could detect that this were the case? “Do I believe, for example, that by using magic I could fly? No. How would […]
Could the Universe have been born completely uniform and still given rise to us? “First, you should check out my house. It’s, like, kinda lame, but way less lame than, like, […]
China’s new satellite is going to attempt to create uncrackable encryption using quantum mechanics.
And could every black hole our Universe creates give rise to a baby Universe itself? “Man is something that shall be overcome. Man is a rope,tied between beast and overman — a rope […]
All pointing toward the Standard Model plus General Relativity not being all there is. “The Universe is very, very big. It also loves a paradox. For example, it has some extremely […]
Gravity is the oldest fundamental force ever discovered. Might it not be fundamental after all? “The whole edifice of modern physics is built up on the fundamental hypothesis of the atomic […]
One of the fathers of string theory proposes a new equation that may reconcile general relativity and quantum mechanics.
Here are five ORBITER-recommended podcasts sure to challenge your thinking on what it means to be human in this world.
Even if the Universe grows to infinity, there might not be enough space to hold all the possibilities. “We are actually living in a million parallel realities every single minute.” –Marina […]
Sorry to all you ‘Flash’ fans out there; it’s not reality yet. This article was written by Sabine Hossenfelder. Sabine is a theoretical physicist specialized in quantum gravity and high energy […]
Did they perform their analysis sub-optimally? Maybe. But gravitational waves were seen no matter what. “We hope that interested people will repeat our calculations and will make up their own minds […]
Students at an English university have demanded that their curriculum be “decolonized”. What does that mean?
Either momentum truly is conserved and this isn’t a reactionless drive… or else. “The law of the conservation of momentum is the basis of the static thrust equation, the law of […]
