Is quantum theory really as random as it seems?

Mer, 25/08/2021 - 20:00
The maths suggests the reality we get from quantum probabilities is random, but there might be some hidden determinism at play – or perhaps the present can influence the past

Wildfires give a window into our planet's future

Mer, 25/08/2021 - 20:00
Directly linking wildfires to climate change is still a difficult task – but make no mistake, they are a sign of things to come, writes Graham Lawton

What putting big things in quantum states can tell us about reality

Mer, 25/08/2021 - 20:00
In principle, there should be no limit on how large objects can get and still display quantum behaviour like superpositions. Physicists testing the idea hope to reveal clues about quantum gravity

Scientists call for urgent investigation into covid-19 animal origins

Mer, 25/08/2021 - 18:00
Scientists say the next phase of the covid-19 origin investigations needs to start urgently, calling for renewed focus on the animal origin theory rather than the lab-leak hypothesis

Quantum Darwinism: Can evolutionary theory explain objective reality?

Mer, 25/08/2021 - 18:00
Quantum phenomena “wash out” as particles interact with the environment, but classical properties survive. Are they selected in a process analogous to evolution by natural selection?

Do we distil reality from the quantum fog or does it exist without us?

Mer, 25/08/2021 - 17:00
Quantum objects exist as clouds of possibilities, only manifesting as something definite when we look at them. The implication is that we make reality – but objectivity may yet be rescued
