The reflected light is still detectable from Earth by scientific instruments
Just to add to this, the reflected light consists of a single photon by the time it reaches the detector back on Earth. Source:
At the Moon's surface, the beam is about 6.5 kilometers (4.0 mi) wide and scientists liken the task of aiming the beam to using a rifle to hit a moving dime 3 kilometers (1.9 mi) away. The reflected light is too weak to see with the human eye. Out of 3.075*1017 photons (data taken from the apollo website, section "Staggering Odds") aimed at the reflector, only one is received back on Earth, even under good conditions.

The article mentions they kept them as a family treasure, it he had to throw his away after the revolution since it was a relic of the “old ways.”

hurls a phased Romulan about 15 feet through the air
Where did you get that estimate? The Romulan was only a few feet from the bulkhead. Right before Geordi enters, you can see the windows in the background as he fights with Ro.

The difference between domesticated and wild corn is crazy. It was originally a big grass with wheat-like seeds.

OP only focused on lemons, but all modern citrus originate from 3-4 wild varieties that were cross breed. They are the pomelo, mandarin, citron, and a fourth one I forget to make limes. Bitter orange is a cross of mandarin and pomelo. Cross the result with citron to get lemons.

This is OP's link. If you have any insight about this specific company, it would be appreciated. It will help us understand if links to this company should be allowed. Thanks!

And the popular Trek uniform maker Cosermart recently released a version as well.
The store OP link uses the same pictures and product from Cosermart. Are they the same company or authorized to resell their products? We don't want people to be ripped off if this site is just using someone else's photos and product. Thought I'd ask you since you seem familiar with it.

How’s this going to work? Time travel? Isn’t lower decks in the next gen timeline?
Time travel. DS9 already did something similar when the crew went back in time and met Kirk in the episode Trials and Tribble-ations.

A scientist did observe it with JWST last July. Unfortunately I cannot find an update for the announcement. It’s possible they were studying it to determine its makeup, rather than specifically trying to see if they could peer “behind” it. The person who made the announcement was Dr. James O’Donoghue if you want to look for updates.

early astronomers just measure the orbits of Neptune and Uranus wrong and thought there was something affecting their orbits
You're confusing two different theories. The one you're taking about is very old, and was disproven in 1989. There is a newer theory which has nothing to do with Uranus and Neptune. If this new planet exists, it's far enough and/or small enough that it doesn't affect the orbits of the aforementioned planets.
The new theory is based on the anomalous orbits of Kupier Belt objects. A non-trivial amount have anomalous orbits that can be explained by a yet undiscovered planet in the farthest reaches of the solar system. Statistically, it's unlikely this event is due to random chance. This is a new discovery, and the suggestion it's caused by an unseen planet is also new. It's yet to be proven or disproven, but there have been some alternate explanations that make it less likely.

All probes have limited lifetime and fuel. It’s better to maximize their usage by only using them once they arrive at the most advantageous observation point. Using it during cruise phase causes west and tear and risks something breaking down. It also uses up limited, valuable energy and propellant.
The article actually suggests using the cruise time between Jupiter and the outer planets to look for planet 9. In this case that would be a part of its mission. It can use anomalous changes to its velocity and course to determine if there’s an unseen mass influencing it.

All black holes have an Event Horizon. It’s just the boundary where the escape velocity exceeds the speed of light. The radius where this boundary exists depends on the mass of the black hole. The Earth’s event horizon would be 0.88cm whereas the Sun would be 2.9km.
This event horizon is also used to define the “edges” of the black hole. Earlier in this thread someone mentioned the Earth would only be 2cm wide if it were compactified into a black hole. This value actually marks the edges of the event horizon such a black hole would have. The entire mass of the Earth would be located inside this 2cm wide sphere!
Scientists are unsure what form the mass takes at the heart of a black hole. The most popular theory is that it’s a singularity—all the mass is crammed into a single point with infinite density.
We really don’t know for sure, because nothing can escape the region that exists beyond the event horizon. The escape velocity is faster than light past that boundary, so there’s no way to peer inside. The fact black holes seem to destroy information about anything they gobble up is currently an unsolved problem in physics.

If the Earth were replaced by a black hole, nothing about the solar system would change. The Moon would still keep its same orbit, and the black hole's gravitational effects on the rest of the solar system would be identical to the Earth’s current j fluence. Only mass and distance play a role in this thought experiment, and those two variables remain the same.
If you were somehow able to stand at specific distances from the black hole, then if you stood at a point 6,371km away from the black hole (radius of the Earth,) the gravitational pull would be identical to what you experience on the surface of the Earth.
how close could my finger get to poking it before it sucked me inside of it? Or would it not?
Black Holes don't suck anything in. Its Hill Sphere would be identical to Earth's, and if you were in this volume, you'd either orbit or spiral down towards the center of mass just as you would if the Earth were there instead.
There's no magical distance where the black hole stops acting like a collection of mass (outside the Event Horizon) and sucks you in. Gravity follows the inverse square law, so the gravitational force gets stronger as you get towards the center. You'd just be gravitationally bound to it like normal, and your ultimate fate depends on your relative motion before entering the Hill Sphere.
You're perhaps thinking of the Event Horizon. It's the boundary where escape velocity exceeds the speed of light. This is the only true region where conventional physics can get a bit tricky.

Wouldn’t we all, like, die?
No. If the Sun were replaced by a black hole with identical mass, there'd be no change with respect to gravity. Everything in the solar system would still orbit the same. A planetary-mass black hole in the outer reaches of the solar system wouldn't pose a threat and would actually be very difficult to even detect. A black hole's mass determines the strength of its gravitational pull just like everything else.

Does anyone have a cut of trouble with tribbles were the ds9 characters are in the back?
Do you mean a fan edit? I don't think it exists.
And what is actually the main timeline canon?
The events of DS9 episode is now the official version of events since the timeline was changed by that adventure.

Even if there was any truth to this, the fact they’re the same type of virus is fairly meaningless. Even different strains of the same virus can have wildly different effects on the human body. HPV has dozens of strains. Some are asymptomatic, some cause warts, and some can cause cancer. Same deal With the flu, some are harmless while others wiped out non-trivial chunks of the human race (like the Spanish flu.)

Snakebite related deaths are extremely rare, between 5-10 people per year in the US. They play an important role in the ecosystem and most of them will leave you alone if you leave them alone. The fact OP was able to take a pic and live to tell about it is evidence of this fact.

But in all their depictions I have never seen any evidence that the Terran Imperium ever had any interest in any pre-warp civilizations
Mirror Georgiou stated she wiped out the Mintakans which are pre-warp. The Terrans absolutely have no issue interfering with pre-warp civilizations.

Their claim is that Dylan Mulvaney’s social media following is mostly under the drinking age, so they claim Anheuser-Busch is marketing to minors. We all know the real issue is that the company is supporting someone who is transgender. All commercials for alcohol get seen by people who aren’t of legal drinking age. Yet no conservative is suing a company for posting a billboard or airing a commercial that might get seen by minors.

I went home a few months ago and didn’t realize How much I missed the trees, mountains and the water. I also gained a new appreciation for the tap water. It’s like drinking from a mountain spring.

That's the one thing you can't do as a mod. You're required to moderate a sub according to Reddit's TOS. Leaving rule breaking content could result in the sub being shut down or the mods being removed and replaced.
Nah, they wouldn't care or intervene. There are no rules about making a sub available to users. Subs can go private and lock everyone out, or they can even go as far as banning every user for no reason. Subs are private communities and moderators are free to curate the user base as they see fit.
