Creationists actually appear to function as destructionists for the most part. My assumption is that they want to speed the onset of The Rapture(TM).
It's certainly very depressing.Lets see, in 500 million years the sun's output will make life on earth impossible already and in about 4.5 billion years the whole planet will be destroyed by the sun going into the red giant phase of its existance soo is that apocalypse enough?
At the rate we're going with getting farther than the International Space Station, we'll need that time.I didn't like the 500 million year thing.. kinda like aaaaah????we have to hurry with getting off this planet aaaaaaah!!!
we "only" have 500 million years left aaaaah!!!!!

Picard: "Make it so."If we were sufficiently advanced, we could make the Sun last longer and reduce its luminosity by reducing its mass. For stars with a mass of between 0.43 and 2 solar masses, luminosity goes as the fourth power of mass (although luminosity also increases with age on the Main Sequence, which leads to a time limit for action of 500Ma rather than 4.5Ga). To reduce the luminosity by 5%, one would need to reduce the mass by about 1.25%. Lifetime on the Main Sequence is approximately 10^10 years * (M/Msol)^-2.5 so reducing the mass by 1.25% would mean the Sun would stay about 1.6% longer on the Main Sequence or about 160 million years, assuming it has already fused about half the hydrogen in its core. If we sent the removed mass outside the solar system, rather than keeping it near the Sun, the planetary orbits would increase in radius by 1.25% (conservation of angular momentum), further reducing the power per unit area received from the Sun by about 2.5% (inverse-square law).
Perhaps we could remove mass from the Sun by magnetic field manipulation, increasing the strength of the solar wind? Currently, the Sun loses about 2.5×10^−14 of its mass each year due to the solar wind. The mass loss due to nuclear fusion is about 6.5x10^-14 solar masses for a total of 9x10^-14 solar masses. That's about one Earth mass or a paltry 0.0003% of the Sun's total mass every 40 million years. This sounds like fantasy engineering, but we might need to do it someday.
I just re-read the entire thread, and I'm satisfied with my posts, whether I was replying to you or someone else.I believe that the question, "Will growing religiosity in the world by 2050 hurt science and space development?" Simply because some of the people on this thread may not possess a respect for people of religion does not mean that they are entitled to make fun of it. Respect everyone and argue logically. If you have an opinion, share it, but have a reason prepared. Making fun of religion is not fun.
