One of the stages in hydrogen production after electrolysis is to run the hydrogen through a compressor and that can take a lot of energy. Would it be possible to run an electrolysis setup inside an already high pressure hydrogen tank so that the hydrogen being separated during the electrolysis...
Suppose in a Vacuum with no external influences we have two particle accelerators pointed at each other. They're maximally precise and one fires an electron while another fires a proton. Both the electron and proton have the same amount of momentum such that their x-axis velocity completely...
Let's say you have two extremal black holes containing the maximum amount of possible charge. Now let's say they're orbiting each other such that they will eventually merge. As the black holes merge they are producing gravitational waves. Once the merger is complete the new black hole mass will...
A popular theory is that black holes gradually leak information because of black hole evaporation due to hawking radiation. When black holes merge, a significant portion of their mass is converted into gravitational waves. If it's true that black holes leak information due to hawking radiation...
As you fall through the event horizon, for a time one part of your body is inside the event horizon and the other part is outside. At that point the two parts of your body are casually disconnected. So shouldn't it be severing the chemical bonds holding your body together at the point of the...
In this example both the proton and electron have the same momentum so the electron is traveling at a much higher speed compared to the proton. Presumably the electron in this would be accelerated to a much higher speed so everything is canceled out. Also isn't the neutrino pretty much...
Lets say, in zero gravity space, you have an incredibly precise collider that slams protons and electrons into each other as perfectly as possible such that all momentum is canceled out and the resulting neutron has no velocity relative to the observer. As protons and electrons continue to...
I saw a fascinating video from PBS space time about dissolving an event horizon. See here for reference:
The video addresses rotating kerr black holes and charged black holes, but doesn't talk about the combination of rotation and charge. So what happens when you spin up the black hole as...
Minute physics made an interesting video for laymen describing the feasibility of muon catalyzed fusion, specifically stating that the current state of technology would lead to an endothermic process. I was wondering if it would be possible to use muons in different fusion configurations, for...
I'm referring to proposals that suggest putting large reflective surfaces at the L1 Lagrange point.
I've also been thinking of something like capturing a nearby asteroid and turning it into an artificial ring at the equator or dumping lots of small infrared reflecting particles or releasing...
Hello,
I wanted to get a physics analysis of the best way to drive an electric car for maximum range. For example, would it be more efficient to drive on side streets at a slower speed of say 30 mph, or would it be better to get on the freeway and drive 60. Should I be accelerating as slowly as...
There's an MIT lecture on youtube where they talk about novel high temperature super conductors and how it will vastly benefit fusion. He claims that these higher temperature super conductors can generate a stronger magnetic field with just liquid nitrogen. They also claim that keeping the...
I saw this national geographical documentary at some point, and it said that when India collided with Asia hundreds of millions of years ago, it formed the Himalayas which ended up uncovering huge amounts of limestone. That limestone in turn reacted with CO2 in the atmosphere and caused an ice...
Wikipedia has much more efficient examples:

In 1998, Danish physicist Lene Vestergaard Hau led a combined team from Harvard University and the Rowland Institute for Science which succeeded in slowing a beam of light to about 17 meters per second,[1] and researchers at UC Berkeley slowed the...
