Round or flat Earth?

[Faster With Feeling]

What's your opinion?

Plus keep in mind that the Earth doesn't actually have any gravity of it's own. Nothing does.

There are no invisible particles or waves pulling us down.

A better explanation is that the mass of the Earth deforms the fabric of spacetime. The immediate area is then bent and curved- causing space to push down on us.

There is no pull. It's a push.

pull... push... what does it matter?

for all you know using the time-space curve like a trampoline is the secret to FTL travel.

Don't have an opinion, it's obviously not flat though, unless you believe in the holographic theory

Holographic theory?

Please elaborate

Yes. That essentially is it.

They got the physics correct in Star Trek back in the 60's. The Enterprise wasn't moving at all(except when it slowed to impulse or thrusters.)

The "warp"engines were bending space itself. They also would have been the life support(something the got wrong.) The warp bubble would have had to on the inside also created a second bubble in which everything was 1G in order to give them a normal living environment. Otherwise they couldn't function in microgravity for extended periods of time.

However, we have known the theory for warp drives for that long- and it is very likely that we will never actually build them. It gets worse too. Even if we somehow managed to build one- it is likely that the energy requirements are so great that it couldn't be used.

It's a flat bowl under the dome with holographic sun moon and planets rotating around.

Messaggio originale di Devsman's Comet:

Centrifugal force is the kind of thing you could justify if you started physics all the way over from scratch, but it's generally considered nonexistent. We tend to think we experience it because we tend to think of ourselves as the origin of a system. For example, when you go around a curve in a car, the car door pulls you to make you go in a circle. But it's easy to mistake this for you pushing the door, especially in extreme cases like when something breaks.

Centrifugal force is not considered nonexistent, and is the explanation used for Earth's equatorial bulge. In the example you mentioned, we are not the origin of the system, just the item of interest. We do still experience centrifugal force, you're just describing Newton's 3rd law. Forces don't pull, they specifically push in whatever direction, which will be away from the axis of rotation for CF. In the car example, this means away from the direction you're turning in, and since you have low mass and aren't part of the car, you slide towards (and sometimes into) the door.

As for the Earth, the CF is typically less because of the much lower angular velocity, combined with gravity directly going against it. If the Earth were spinning much faster, the bulge would be greater and gravity would be much lower at the equator due to CF.

It's actually a very important part of classical mechanics, along with the Coriolis force, but that one only applies when moving while on a spinning object rather than just merely existing on it. Both Coriolis and CF are highly important for long-distance artillery as together they will deflect your projectile based on the direction you're firing in.

Like I said, anyone with access to Google can confirm.

what's even more hilarious is that futurama got it right...

star trek is massively under-appreciated tho... pretty much everything they did in classic trek was well researched and theoretically possible.

The equatorial bulge is from the centrifugal force created from angular velocity. We should be grateful we have a moon. Stops the Earth from wobbling too much on its axis.

But to be clear, the Earth is very, very round. The bulge is almost imperceptible.

And I agree, gravity is strange force. It's almost like the consequence of mass. I picture it like a hollow 3d cube with a lattice-work of spiderweb-like strings spaced evenly on the x, y, and z axis. Put a object with mass in the center and all the crisscrossing strings nearby pinch/bend in towards the object.

Gravity is not detectable at the quantum level.

why you ask question if you don't want answer?

The only one being obtuse here is Pierce Dalton, because he suggested it's in the shape of a triangle. >_>

Devsman is acutely aware of his word choice - make no mistake

Aa a gambling man, I just think - what are the odds the Earth is flat when every other heavenly body is round. Is like one in ten odds?

People already are fundraising off of this one:

The Earth is round, and that is not an opinion, that is a fact.

operation fishbowl proves we live in a dome.we can never leave earth. they won't allow it.
admiral Byrd proves we have a hallow earth and what they tell us isn't the truth.

we don't live in a globe or a flat earth. bcuz no1 truly knows. escape your indoctrination sheep

many many countless videos of nasa lying.
nasa is funded by bankers and profiteers.

u would trust a banker? aka snake oil salesman

dont beleive everythjng u see on your teLIEvision kiddos. they don't have ur best interest. just beleive what u r told and consume and buy..
