[@awfuldynne]

@@ominousscreech4054 Based on "I'm happy with traveling [0.3c]", that sounds like The Exoplanets Channel is riding on the spacecraft, which appears to rule out a laser-boosted solar sail-unless, I suppose, the laser is still focused enough to use for braking as the craft nears its destination? But also I don't see a way to deflect the laser to brake in the direction the laser is already pointing. If you can't brake before your destination, at those speeds you're basically left with lithobraking, because atmospheres are too thin. Ionic propulsion seems too slow as well, but on a long trip, it's a lot faster than coasting the majority of the trip. But there's also the nuclear option, which involves heavy shielding, and riding the blast from a series of nuclear explosions. I don't know if you get better "fuel economy" using shaped charges. Seems like a bumpy ride, though.

Start by running at full speed, That should get you pretty close. Then what you want to do is slowly lean forward (Remember to keep your balance so you don't fall forward). Once leaning at about a 100 to 120 degrees depending on your own preference. After this, just throw your arms back, after about 1 to 2 seconds of self- thought and encouragement the boost should kick in. Now you are moving at lightspeed.

[@codyhameha7107]

Since black holes don’t admit any light (including infrared), are they effectively absolute 0?

[@TH3F4LC0Nx]

I don't think so because they suck in a lot of stuff that gets superheated and then they violently expel all the stuff they've taken in after a time.

[@Enderdragon91]

@@TH3F4LC0Nx Well yes and no. Black holes expel some material that they are attempting to suck in due to the strange way they way space-time and their magnetic fields. So in that sense, yes, that material is superheated and expelled at a not-insignificant fraction of the speed of light, while also producing x-rays from the energy imparted on it. But there's another reason why black holes have temperature, and that is Hawking radiation. Over a long, long, unfathomably long period of time, black holes radiate their mass outward, particles and energy escaping the event horizon through strange quirks of how quantum fields work. It's usually explained as virtual anti-particle/particle pairs appearing on the edge of the event horizon, such that one of the pair falls in, and the other is sort of... made to exist, flying away from the black hole and taking a tiny, *tiny* fraction of it's mass and energy with it. In that sense, black holes have *heat* as energy radiates away from them.

And my thought goes to wondering if you can use a Bose-Einstein condensate to super impose lasers on themselves to increase the intensity over time, allowing for a more powerful beam to be generated.

Speaking of Cherenkov radiation... I've been privileged enough to have worked on two different Cherenkov detector experiments. The first is difficult (and expensive, though there might be some NSF outreach grants to help cover some of the costs) to visit to do a video on, though the primary institution is easy enough to reach at UW Madison. This is the Ice Cube Neutrino Observatory installed at the South Pole. Detecting neutrinos by looking for the Cherenkov radiation given off by a Muon which is the result of a neutrino colliding with an atomic nucleus. The second project is easier to visit since it is installed at the base of Mt Hopkins in Southern Arizona (the telescope array is actually installed around the visitor's center for the Fred Lawrence Whipple Observatory). This is the VERITAS gamma-ray observatory which looks for the Cherenkov portion of air showers that are generated when cosmic gamma-rays hit the upper atmosphere.

What if two scientists measure a photon? Would they get the same location or due to it taking time to take measurements, would each scientist dispute where that particle was

Unfortunately photons are so small that you can’t actually observe one in both methods at once.

[@a-blivvy-yus]

Yes. -This answer is in a quantum superposition of being both that they would measure the same location and that due to the time taken to meaasure it, they would dispute where the particle was.

I suppose I don't understand your question. There are shock absorbing materials that when thrown at a hard surface don't bounce at all.

Sure under right circumstance you can move faster then light but in order to reverse time you must be able to travel faster then causality. Causality give light its speed. If the speed of causality changed so would the speed of light.

This video is brilliant! I learned how refraction works (I thought more dense media were simply harder for photons to travel through), I learned the 5th state of matter & saw how to make light go at 1 mph.

I came for the speed of light but stayed for Kyle drinking water.

Talking about going faster than light without changing relativity is by time. When the experiment of stopping light entirely without removing the energy that the light contain it is still traveling as fast as it was before but the energy is being distorted in way that it doesnt lose or gain. It's like holding a ball. The ball isnt moving in your hand but it still contains energy. So the light that is stuck or isnt moving is like the ball. Its in a potential state. The moment you changed the temperature up the potential becomes kinetic and moves on. Oh by the way if you control relativity you control time. Since time is a base line of making something exist or be relevant. Than light is traveling at the velocity that is both potential and kinetic at the same time. That's how I see. But if you look at time as you travel faster it slows down. Time will only stop to a medium that far exceeds light which is a black hole.... Which reminds me of isaac newton's theorys about gravity. Gravity can stop light, twist, and bend. As it also can stop time. It's a mind boggling theory.

"When typically interrogated" I like to think about two scientists just screaming at a lightbulb strapped to a chair

For anyone interested, look up optical flats. You can see canceled light wavelengths

This 11 minute video explained everything so much better than my science teacher did last year.

"Have you ever seen a sunset?" sounds like a solid follow-up to Kermit's #1 hit, "It's not easy being green."

[@dannyarcana0017]

So essentially, slow light down to be faster than it, like in one way to win the olympics all you gotta do is break all the competitors' legs

[@Hoshimaru57]

Something I’ve always found strange is that light does not accelerate or decelerate. But that would have to be impossible. If you go from no photon a photon there has to be some point at the exact moment it comes into existence that it starts being light where it becomes the speed of light. Granted it could be a Planck time or a fraction thereof but it must exist.

[@scyberclops]

Not only have you not actually seen the sunset, but the one you’re looking at actually happened almost 500 seconds ago so you’re actually not seeing it anyway. What you’re actually seeing is a little more than eight minutes in the past

4:43 "Does that material exist?" Immediately got an ad saying: Dawn PowerWash Dish Spray lol Had to check my phone because I was listening in my bed 😂😂

So theoretically if we can stop light in its tracks... could we figure out how to keep it stopped, and then actually begin to create objects from pure light?
