It won't be that different the rest of the week. definitely not a "one night only" event.

Very few do. But there is one group, the A Train

https://en.wikipedia.org/wiki/A-train_(satellite_constellation)

Set of sun synchronous satellites from various countries that arrive together to combine their instruments.

What you are most likely seeing is a mixture of the human habit of seeing patterns in random noise and the affect of unconsciously looking more for satellites when you notice one, plus seeing them in good viewing conditions makes seeing them more likely.

Worth noting you really only see them close to dawn and dusk as there still has to be sunlight up above to reflect off them.

U might be seeing starlink. They launch a rocket that carries a bunch, then releases them. So for awhile they are very close and slowly spread away

That video was more about China's energy independence.

1. build a magnetic satellite network shield around the moon.
2. strategically place massive nuclear bombs around the entire moon, evenly spaced.
3. explode said nukes.
4. wait 10 years for radiation to dissipate.
5. terraforming complete.

Starlink satellites are deployed in batches, usually around 16 in a group as they are launched and then slowly fan out and move to their designated grid position around the globe. Other satellites, not so much

If there was a string theory/multiverse where realities are seperated into different universes themselves...are gravitational waves like tsunamis, forcing the realities to be squeezed together, and maybe..for an instant, you could occupy mutliple points of reality in the same point?

Venus* we came from Venus, Mars is next when we've depleted Earth/it can no longer sustain humans.

Speculative, and yet saddening

Dark matter and dark energy is called dark because we literally know nothing about it. It's like a place-holder moniker until we can observe the phenomenon.

We have a better idea of what Hawking radiation is because its effects have been observed and measured.

I think everybody in this comment section deserves a whoosh except for Ken

Rocket Lab got to orbit with less and SpaceX got to orbit with not too much more.

I'm a firm believer that if you can build a dyson sphere you don't need a dyson sphere. You'd have figured something else out well before then.

Hawking radiation IS dark matter. If you calculate all the Hawking radiation you reach a total that's -precisely- the amount predicted by the Standard Model.

> It is insanely so. x100 more difficult. If it wasn't, someone else would have landed an orbital rocket by now, when they landed a suborbital in the 90s.

It's not insanely difficult, it just hasn't been tried very often. Every program that tried VTVL rocket landing has succeeded (DC-XA, Blue Origin, SpaceX). It just hasn't been tried much. The reason it hasn't been tried much is because reuse hasn't been prioritized or done very pragmatically. Prior to the 2000s most RLV development focused on unrealistic designs such as the Shuttle or SSTOs, not on simple two stage launchers with booster reuse. More so, there hasn't been much competition in the launch vehicle space until the 2000s, for a variety of reasons, so extreme cost competitiveness wasn't a major factor until then.

Additionally, there are many natural optimizations that have traditionally been made with expendable launchers which deoptimize them for booster reuse. Expendable launchers tend to have simpler, lower cost first stages with only a few engines (Delta IV, Atlas V, and Ariane 5 only have one), while the majority of the cost and complexity is pushed into the upper stage. This makes first stage reuse much harder, especially in the VTVL configuration (it's very difficult to throttle down a single huge engine vs. simply turning off extra engines) and it makes it useless, as you end up simply saving the cost of expending the cheapest part of the rocket. You have to go into two stage launch vehicle design while planning ahead for VTVL first stage reuse to actually make it worthwhile. The genius of SpaceX was that they made very pragmatic design decisions that aimed at reusability straight out of the gate, and they figured out how to do the R&D for reuse within the context of paying commercial customer flights, making use of "thrown away" hardware that created the equivalent of a billion dollar funding stream. But much of that can be copied by anyone paying attention. SpaceX may have some degree of "secret sauce" that drives their success, but simply achieving VTVL reusable rockets is not it alone.

It’s a possibility if aliens looked like squirrels millions of years ago, but yeah bigger chance there’s Bigfoot out there then us not being true primates.

Keep in mind, Ken is a blonde toy originally from '61. During those days up till about the mid 90's the stereotype of being blonde meant that he might be a little bit daft. Of course now that we are in the modern era, this would be inappropriate, so lets chalk it up to him being a boomer with no humor.

There are full theories about this. https://en.m.wikipedia.org/wiki/Nordic_aliens

Hawking radiation is in the form of photons, and there is nowhere near enough to accelerate the universe’s expansion
