"Outer space is not entirely empty; it is filled with a thin, scattered distribution of matter known as the Interstellar Medium" Yes, effectively there's no such thing as "nothing" ! | |||

"How do we know the earth is round unless you have been up to space can it be proven we only see what they want us to see !!! " Go to the seaside. Look at the horizon and hold a straight edge to where the sky meets the sea. Youll see a curve downwards at each end of the straight edge proving the world is round. Try it anywhere by the sea its the same world over. | |||

"Can anyone comprehend why we are on this ball and what is it all about?" Of the marvels of our very existence, we may stand in awesome wonder, but perhaps ours is not to question but to accept, and trust that, eventually, all will be revealed. | |||

"What happens if you go into a black hole? xx" It is possible that we could already be living inside a giant black hole from another dimension. Some physicists think black holes can create new universes. So the black hole that made ours would be in a "higher" reality with more dimensions than the three we experience. We’re on the inside looking out, but we can’t see past the edge. | |||

But an oblate spheroid is, by definition, round — just not a perfect sphere, but generally round nonetheless! | |||

"With the Moon at its furthest point from Earth.. All the other planets in the solar system could fit between . Hogwash The moons apogee is 252,088 miles Assuming Jupiter was resting on the surface of the Earth and for some bizarre reason the gravity didn’t crush us and the radiation didn’t kill us it alone would take up over 75% of the distance. Add Saturn in and that distance has already been overfilled. Where do you put the other five planets (not including Earth). Not to mention several dozen dwarf planets | |||

"With the Moon at its furthest point from Earth.. All the other planets in the solar system could fit between . Also..Jupiter is 143,000 km in diameter at its equatorial point ( which includes the bulge rotation) which is not 75% of the distance between the Earth and the Moon...that's according to NASA anyway. | |||

"Space is expanding. The galaxies are all moving away from each other. Eventually, billions of years from now, there will be nothing at all to see in the night sky..." Not quite true. There will be stars to see in our own galaxy, regardless of what happens to other galaxies. In any case, some galaxies exist in clusters. Our own galaxy - the Milky Way - has many satellite galaxies, the biggest being the Large Magellanic Cloud, which is projected to collide with our galaxy within the next 2 billion years. | |||

The Earth isn't" You’re mixing up “round” with “perfect sphere”. Round just means curved with no corners or edges. Earth qualifies. So do eggs and watermelons. Even your billiard ball isn’t perfect under a microscope. Earth’s equator bulge is less than 0.4%. Scale it to billiard-ball size and it’s smoother than the real thing. Earth is undeniably round!! | |||

According to you.jupiter is 189,000 miles in diameter at its equatorial distance..( if as you claim its 75% of the distance between the earth and the moon).Nasa says its 88,000 miles..nowhere near your stated 75%.distance..

"The universe is so big we will never be able to see as far as the edge (if there is one). Distances are so great that we will never be able to travel to Proxima Centauri our nearest star let alone any of the other trillions of stars out there. Conversely Aliens have never, and never, will be able to travel to Earth. (I'll sit back and let the conspiracists have a go)! We can definitely travel to Proxima, it will just take a very long time and would require either a generation ship or some way to put humans into hibernation. There are already viable plans to send tiny probes there via directed-energy propulsion which would reach it in a few decades. Aliens COULD visit Earth if they wanted, were close enough and had the right technology/biology, but I agree with you that I don't think they ever have. | |||

Aliens COULD visit Earth if they wanted, were close enough and had the right technology/biology, but I agree with you that I don't think they ever have." To travel to Proxima Centauri at say 50,000 miles an hour would take more than 57,000 years, at a quarter the speed of light it would still take more than 20 years given to slow down to orbital speed would take several years. However the bigger problem is that to travel that far at a quarter the speed of light would need more fuel that currently exists on Earth. Trying to go even faster only compounds the problem. Aliens are bound by the same physics as we are, so have the same problem. | |||

There are thousands from the flat earthers just because they are there doesn’t make them correct Except I didn't mention all the dwarf planets included.. .389704km is less than the distance between the Earth and moon at apogee..so as I say ( from nasa website ) yes the planets can fit between ..why did you include dwarf planets in your attempt to disprove the opening post?..what will you add next,the sun,.you've already contradicted yourself in writing by now stating the correct size of Venus...which is not 75% of the total distance between earth and moon.. By the way Nasas website information is in metric...which is i believe is an American organisation ..so what do you mean America never got metric . When I was born Pluto was a planet. Dwarf planets is the new NASA clarification for small planetary objects. They exist fact and they are one of the most numerous objects in the solar system and according to NASA. They are planetary bodies As to Americans not getting metric. Please look up the Mars climate orbiter NASA uses a hybrid system of metric and US imperial standard.

So given your statement that you were taught Pluto was a planet( so was I in 1960s.)the common definition of solar system planets is commonly total 8...rest are dwarf planets etc etc..so my information in opening post was all the planets CAN fit between the Earth and the moon at apogee..which i wrote word for word from Nasas website.... Yes if all dwarf planets,asteroids,etc were included then they wouldn't fit..but I and Nasa assumes the logical current day quota of 8 main planets( although Pluto would fit also) .. Next door to me is a gentleman who teaches astrophysics at a local university..I asked him two things. 1 .how many planets in the solar system? He replied 8... 2 .would the 8 planets if Pluto included,fit between the Earth and moon at their furthest..he replied yes.. Its illuminating what his theoris are on black holes etc.. So not Hogwash.. but correct.. So you include one dwarf planet but not the other 30 named ones. Some of which are in the size range of Pluto one or two even bigger. Nothing quite like bending the facts to fit your required result" . I dont.Nasa do.all the planets plus pluto is what Nasa says fit between...yes I know some dwarf planets are bigger than Pluto.. Question ..do you accept the Eight planets or even seven if you like,would fit between the Earth and moon at furthest distance..yes or no ? | |||

"Why would anyone want to try to fit all of the planets between the earth and the moon? Wouldn't it rather screw up life on earth, especially if we got a gassy one next to us? " Yes.its only an interesting fact that they'd fit.. | |||

"We can definitely travel to Proxima, it will just take a very long time and would require either a generation ship or some way to put humans into hibernation. There are already viable plans to send tiny probes there via directed-energy propulsion which would reach it in a few decades. Aliens COULD visit Earth if they wanted, were close enough and had the right technology/biology, but I agree with you that I don't think they ever have. To travel to Proxima Centauri at say 50,000 miles an hour would take more than 57,000 years, at a quarter the speed of light it would still take more than 20 years given to slow down to orbital speed would take several years. However the bigger problem is that to travel that far at a quarter the speed of light would need more fuel that currently exists on Earth. Trying to go even faster only compounds the problem. Aliens are bound by the same physics as we are, so have the same problem. Its an efficiency problem. If we can sort out fusion here on earth then maybe eventually we could make something efficient enough. Im not enough of a scientist to suggest what though. | |||

Aliens are bound by the same physics as we are, so have the same problem. Absolutely. You wouldn't use chemical rockets to get to other stars. Aliens are of course bound by the same physics but there are a lot of solutions we haven't discovered or developed yet between present day technology and the limits of physics. As long as you aren't trying to break the laws of physics then it's just a series of engineering problems to solve, certainly not impossible. | |||

"How do we know the earth is round unless you have been up to space can it be proven we only see what they want us to see !!! " Because it is, if its not then where are the edges to it? or just go look at any sea horizon or try flying around it or look at any picture of earth from space or stand still, the fact that you dont fly up into the air is because the earth is rotating generating gravity like a massive old fairground ride where you would plaster yourself against a metal grid with no safety belt and the g force would hold you in place. If the earth wasnt round this wouldnt happen | |||

"A friend of mine wrote a book with his pal of space themed poetry called Binary Stars. It’s beautifully illustrated too. All 3 are queer guys but the book isn’t necessarily overly queer, it’s more about space and wonder and love and melancholy. It’s great. You can get it from Waterstones and Amazon but Amazon print it on demand so the quality isn’t as good as the Waterstones copies. ISBN is 9781917842532 if it sounds interesting to anyone. Fun fact: one of the writers initials is NASA. " Ok that's my next read!! | |||

"How do we know the earth is round unless you have been up to space can it be proven we only see what they want us to see !!! Go to the seaside. Look at the horizon and hold a straight edge to where the sky meets the sea. Youll see a curve downwards at each end of the straight edge proving the world is round. Try it anywhere by the sea its the same world over." I’m not sure this straight edge works as it is easier proved by geometry to be otherwise. But to answer the first question all you have to do is measure the angle of the shadows of two vertical posts on the same longitude at midday on the summer solstice. The distance between with a bit of ? will give you the radius of the Earth. First done in the 2nd century I think. | |||

"So the universe is either: Finite (effectively infinity-1) but expanding so fast you could never reach the edge but if theoretically you were to reach the edge its impossible to comprehend whats beyond. Its not just nothing or a vacuum but the complete absence of anything - time/matter/light - existence no lingers exist OR its a huge ring donut kinda shape where you coukd travel so far eventually (in billions of years) you'll come back to the same place. Some describe is like a PacMan universe where you go off one side and appear on the other." If it’s a doughnut, what’s in the middle? Not being facetious, just if the universe has a shape it must have an edge/end, so what’s beyond the edge of the doughnut? | |||

Thats kinda the point - nobody knows. If its finite - and existence doesnt exist beyond it - thats something science/humans can't comprehend. Or its infibite and you somehow eventually come back to the same point like a loop There are other theories but these are the 2 of the biggest. | |||
