Geeze, can we have just one frigging thread without the Trump haters?

I imagine so. Itâ(TM)ll probably take place around the same time we get one frigging thread without Trump sycophants.

Comment Atari (Score 2) 92

I never had a C64 but I still have my original Atari 1200XL, the cassette drive, an external 5.25â floppy drive, and a 32â CRT to plug it into. I even have my original BASIC cartridge and a copy of âoeMapping the Atariâ that Iâ(TM)ve been meaning to show off to my kids (now adults) for 30-ish years. I need to see if I can find original cartridges for JumpMan Jr and other games and original (still readable) diskettes of old Infocom games & one chess derivative game I used to play called Archon. That would be fun.

Reforestation is a thing, at least in North America. Since the 1970s, the U.S. has planted millions of acres of new forest (see United Nations FAO and USDA Forest Service for data). The U.S. currently is planting about 60,000 acres of trees annually, plus another 130,000 acres of regeneration.

The people overseeing this work are forestry experts, so one can assume they are planting the correct trees for a locale, in the right concentrations and groupings.

The real problem is that Brazilians are chopping down millions of acres of forest every year (albeit, decreasing). This is insanity. Also, because of food shortages and famines, some Africans have been stripping bark from trees, as well as harvesting the wood. Deforestation of that continent not only removes habitat for fauna (chimps, birds, etc.) but also leads to expansion of desert. Africa's just a total disaster.

Comment Why not focus on the obvious problems like plastic (Score 1) 70

About a million tons of plastics are being dumped into the oceans every year, and this material is suspected of damaging the ecosystem. Algae absorb CO and emit O quite efficiently; 60% to 70% of the Earth's oxygen is made this way. Another 10% to 20% or so comes from several huge rain forests, notably the Amazon.

We should focus on eliminating plastic and other potentially damaging substances from the ocean, and secondarily perhaps limit over-fishing that distorts the food chain.

Also, plant more trees. There's no better, or cheaper, way to de-carbon-ify the atmosphere than trees, especially during their major growth years.

This seawater-filtering scheme sounds expensive and strange, and probably would create more problems than it solves.

I had thought quantum entanglement doesn't copy information; it actually realizes the original information at an arbitrary point in space-time (I added the "time" because I believe it's not restricted to 3 dimensions).

The teleportation you describe is much more conventional: a machine scans you down to the molecular level (the mechanism, let alone the amount of data storage, needed to achieve this is left to the imagination), transmits this data to Jupiter, which is an average of 43.2 light minutes from Earth.

The receiving machine then rebuilds a copy of you, molecule by molecule. If the checksum matches, it sends a "Success" response, and the transmitting machine then disassembles the original you.

And for the record, I will never get in one of those things.

The gravity is a nice bonus... but acceleration would need to be maintained at 9.81 m/s to achieve one gee.

To get to 100,000 mph by the midpoint to reach Mars at its closest approach to Earth, per Grok, a = 0.0357 m/s
This is far less than one gee.

Unless I'm doing this wrong.

But luckily, we can have a spinning habitat to simulate gravity. For a six month journey, this would be a necessity; it wouldn't do for the astronauts to reach Mars with atrophied muscles and bones.

What happens to the kinetic energy of the astronaut who is instantly transported to another point in space? Standing on the Earth's surface, we are actually moving at a rather high velocity due to rotation and orbital motion. Just plunk someone down on Mars and they might go flying up, down, or sideways at thousands of km/hour.
