Or are those in charge trying to smear him. Watch the WHOLE thing.

Physics, Astronomy & Cosmology / Will this news modify relativity?
« on: 30/05/2021 14:23:51 »
From the BBC.

Physics, Astronomy & Cosmology / Can you measure the one way speed of light without synchronised clocks?
« on: 18/04/2021 13:11:01 »
Is there any method that you can think of that could achieve this? Have a stab at it.

Physics, Astronomy & Cosmology / Is super determinism a valid idea?
« on: 29/03/2021 18:31:29 »
I have heard that super determinism solves issues with the QM measurement problem. Also that everything since the big bang is determined and there is no such thing as free will. Is this a valid idea?

Just Chat! / Useless factoid of the day
« on: 28/03/2021 23:22:14 »
If the diameter of a circle equals pi then its circumference equals pi squared and its area equals pi cubed. A cubic area! My lord the world makes no sense!

Physics, Astronomy & Cosmology / Are photons relative?
« on: 22/03/2021 12:26:25 »
If objects travel with velocities relative to each other then what is light traveling relative to? The photon is a particle and it is traveling. Relative to ...

Physics, Astronomy & Cosmology / How would W and Z bosons act within a black hole?
« on: 27/04/2020 09:26:10 »
These are force carriers critical to physics outside the black hole. If they are forced along a worldline towards a singularity, what would that mean for the integrity of atoms?

Physics, Astronomy & Cosmology / Are there half visible galaxies?
« on: 29/03/2020 14:51:40 »
There is a limit on the amount of the universe we can see. Since the universe is theorised to have started with the big bang. Therefore, if we look out far enough, shouldn't we be able to see only half a galaxy at the boundary of the visible universe? Would we only be able
detect this at some point in our future when the galaxy starts to become visible to us? Due to the vast distances between galaxies.

Physics, Astronomy & Cosmology / Does the energy of a photon affect its path through a gravitational field?
« on: 05/01/2020 01:03:47 »
That is, does a photon's momentum affect its path through the gravitational field in the same way a massive object's velocity would?

Physics, Astronomy & Cosmology / Can the whole universe be considered a quantum system?
« on: 28/12/2019 22:08:00 »
If this is so can no two electrons in the entire universe share the same quantum state?

Physics, Astronomy & Cosmology / Does quantum bayesianism have anything useful to say?
« on: 01/12/2019 17:26:35 »
See https://en.m.wikipedia.org/wiki/Quantum_Bayesianism
Does this clear up the mysticism of many-worlds and other such interpretations?

Physics, Astronomy & Cosmology / Can we detect acceleration in free fall?
« on: 19/11/2019 19:11:44 »
Well this is not the question you might think it is. If a spacecraft is falling freely towards a gravitating body, and then starts accelerating towards the body, would an accelerometer show the acceleration?
I have not seen anything about this online. I would say it would. Is there any observational evidence anyone can point to? Have you tried this personally?

Physics, Astronomy & Cosmology / Where can I find a full list of neutral particles?
« on: 10/11/2019 00:44:14 »
Apart from the neutron is there a list of the other known neutral particles?

Physics, Astronomy & Cosmology / Does the Higgs potential relate to a standing wave
« on: 10/08/2019 00:50:13 »
Is this the wrong way to look at this?

General Science / Does the earth emit EM radiation due to its acceleration around the sun?
« on: 08/08/2019 12:49:32 »
The earth is in free fall around the sun but at the same time accelerating. Einstein said we shouldn't be able to distinguish free fall from inertial motion. So could we detect the emission of electromagnetic radiation from the earth accelerating through the sun's EM field or not?

Physics, Astronomy & Cosmology / Could the big bang have produced Planck mass sized particles?
« on: 04/08/2019 17:04:33 »
If this was possible could black holes have formed very early in the process?

Physics, Astronomy & Cosmology / How well do laymen understand Bell's theorem?
« on: 03/08/2019 12:20:17 »
I just watched this video . It may well help others to understand better. It is a difficult concept to grasp. Let me know if it helped.

Physics, Astronomy & Cosmology / Is the shift in the wavelength of light cancelled during free fall?
« on: 07/07/2019 20:21:50 »
Do the shifts cancel for a freely falling object? Has an experiment been done?

Physics, Astronomy & Cosmology / Can entangled photons unlock a black hole?
« on: 24/06/2019 19:30:02 »
OK, a bit of a tabloid headline title. On to the crux. If we continually entangled photon pairs, sending one into a black hole and the other to a detector, would we be solving the information paradox? Or just wasting our time?

Physics, Astronomy & Cosmology / Can we derive a conic potential
« on: 23/06/2019 19:10:52 »
If the gravitational field were not inverse square in nature, but had the same potential at every point, would this plot as a cone? I have been thinking about light cones. Which is why I am asking such a strange question.
