Startups Are Building Balloons To Hoist Tourists Into the Stratosphere (cnbc.com) 66
An anonymous reader quotes a report from CNBC: CNBC spoke to three startups -- France-based Zephalto, Florida-based Space Perspective and Arizona-based World View -- that aim to hoist tourists to the stratosphere using pressurized capsules and massive gas-filled balloons. "The capsule itself is designed to to carry eight customers and two crew into the stratosphere," said Ryan Hartman, CEO of World View. "There will be a center bar where people can gather, and then, of course, there will be a bathroom aboard the capsule." The balloon rides will last around 6 hours, but will not take passengers all the way to space. Most will reach heights of 15 to 19 miles above the earth's surface, flying in an area known as the stratosphere. The start of space is generally accepted by the U.S. government to be around 80 kilometers, or about 50 miles, above the earth's surface.
Jane Poynter, founder and co-CEO of Space Perspective, has a differing view. "There is no universal definition of space," Poynter said. "We are regulated as a spaceship. If we go over 98,000 feet, we are a spaceship. Outside the capsule, it's essentially a vacuum. We're above 99% of Earth's atmosphere, which is why the sky is so deep black." Compared to rocket-powered space tourism, the physical sensation that passengers will experience on a stratospheric balloon ride is more comparable to being on an airplane. Passengers will not experience weightlessness. "We don't need any physical requirements to board the balloon," said Vincent Farret d'Asties, the founder and chief pilot at Zephalto. "If you can board a standard plane, you can board the balloon."
All three companies told CNBC that they were pleased with consumer interest. World Views says it sold 1,250 tickets so far while Space Perspective has sold 1,800. Zephalto did not tell CNBC how many tickets it sold, but said its initial flights were fully booked. Ticket prices range from $50,000 per seat with World View to around $184,000 with Zephalto. Space Perspective sells tickets to its experience for $125,000 per seat. That's all assuming commercial service gets off the ground. Only Zephalto has performed crewed tests so far, though not at the company's target altitude of about 15 miles above the earth's surface.

According to some quick searching, you can theoretically see the curvature once you reach about 7 miles up, but at that altitude you need to be looking at the ocean so you have a nice, "straight" horizon to look at. I'd guess that more than double that height, which is where these balloons will be, would give you a good shot at seeing it.
I think one of these companies should do a PR campaign where they give a free ride to a couple of the most well-known flat earth influencers and see what happens.

That wouldn't work. They'd just claim they'd been drugged or hypnotized. In fact at that altitude they'd have to be in a pressurized cabin, looking through windows, so they'd probably fall back on one of their favorites: the windows are (a) video screens showing a CGI video of a fake curved Earth; or (b) the windows are acting as fisheye lenses to distort the view and make the flat Earth look curved.

Yes it's the speed of the moon orbiting the Earth and the resulting centripetal force being balanced by gravitational attraction that keeps the moon in orbit. It's the same basic physics of you twirling a string with a tennis ball on it except instead of a string keeping the ball from flying away, it's the gravitational attraction.

No, it isn't. A centripetal force is always towards the central point of the curved path. In the case of the moon orbiting the Earth, the Earth's gravitational force is the centripetal force.

Remember, the "weightlessness" that astronauts experience is caused by free fall that is occurring while a body is in orbit. This balloon would be stationary, meaning gravity will still be pulling occupants downwards towards Earth.

They won't experience weightlessness. That only happens when in orbit, which is basically falling but moving forwards so fast you keep missing the ground and instead going round and round the earth, over the horizon.
The other way to do it is by having a plane dive really fast, so that it's downwards speed equals the speed you are falling at. If the balloon fails they might experience that, for a short time.

The balloon gains height because it is lighter than the air around it. It can therefore never reach weightlessness on its buoyancy. The mass (and therefore the weight) of the balloon is not zero. So the balloon would never reach the upper limit of the atmosphere on buoyancy.
Also, the upper layer of our atmosphere is not reaching the escape velocity, as it would have leaked away a long time ago if it did. So while the balloon might speed up because of the drag with the atmosphere that is rotatin

Orbital mechanics is complicated, for sure. Gravity does not hold things in place. Everything is always falling, unless it is resting on the object it is falling towards. If you are suspended from a ballon, you are being pulled down by Earth's gravity. You are resting on the floor or your chair. The ballon is holding the chair aloft by its buoyancy.
If the balloon should fail, you will for a certain period of time feel weightlessness due to the fact that you do not have buoyancy in the atmosphere like the ga
