Who else thinks leaving things in space is cool?

Yes the influence of the gravity from the sun goes a long way on object of different mass. If you do the Newton's gravitation's calculation it should work out here. My focus is that I don't think the spacetime in Neptune is bent by the sun. So when the mass increases it seems the planet picks up the gravitational force from the other mass based on the equation. But how does the planet picks up the gravitational force? Like a magnetic field exerting current on a wire, speculation

Well, that means the sun would have to bend spacetime as far as Neptune for all nine planets to orbit around it. I find that hard to believe. Higher mass planet is able to catch on sun's gravity, sort of like how God particle give other particle mass

So gravity is described by General relativity as the bending in spacetime. The moon circles around the earth also because of gravitational force based on Newton's Theory of Gravitation. But is the moon's gravity caused by earth's bending of spacetime? Gravity feels more like radio waves to me then the bending of spacetime

I'm thinking of a type of satellite that stays in space. Bear with me for a second, it does now orbit around earth, rather it is placed so that earth orbits around it. I mean whatever you place in space stays in space so it's position won't change. What changes is its direction it observes, like a telescope. Benefit, it is permanent and you don't need to replace it, when you want something else you just collect it back. Maybe there's one built on the moon already, but it's like a space station. This way you don't need to launch a satellite every now and then P.S. I'm saying this because I want to launch my own custom satellite. I mean as long as I can find a way to get it to space using balloons I get a satellite

I found my answer here, interesting adsorption effect. I wonder if it can be applied to nanomachines

So I went from enzyme to catalysis which consists mostly of inorganic substances. Now in a particular catalysis case of manganese dioxide and hydrogen peroxide reaction. How does the manganese dioxide breaks down hydrogen peroxide? Does its shape changes like the enzyme does to break down the substrate?

I want to create a nanomachine built based on carbon molecules to act as different types of enzymes, is this possible? To begin with, I know an enzyme has active site that allows substrate to enter and exit, is it possible to achieve the same with carbon molecules?

So I want to know if a nanomachine can be constructed that reads DNA in the human body in real time as letters. I got this idea when I was reading this paper. So it could be an enzyme that would loop through the entire DNA segments with a wireless device attached that is capable of transmitting the results back, either that or we would have to monitor the result through a fairly detailed MRI using visualization technique. Both should be doable, but do let me know which is a better way. I'll let you guys decide

I believe the article you posted is referring to mutation, please check the distinction between DNA damage and mutation here. Wikipedia: "DNA damage is any physical abnormality in the DNA, such as single and double strand breaks, 8-hydroxydeoxyguanosine residues and polycyclic aromatic hydrocarbon adducts."

Right, thanks for the correction on meiosis. Well, technically all we have to do is to open a few of these sperm cells and check the length of the Telomere as well as if the damaged DNA has been repaired to its initial state. I don't think adding a part of Telomere length DNA to every single cell at my current age 29 is going to help me live longer, there's probably other things at work here (DNA damage). Although I can imagine growing into a younger age 29->28->27. Then again if all meiosis does is a perfect reset that wouldn't quite work out either, no one wants to be a zygote age 29->0. Well, so all we need is to open a few of these sperm packages

Well again, I'm saying it for normal condition of mitosis and if Telomere is repaired during this process

Well, DNA should be pretty accurate in doing the tasks = =, I'm saying this for normal conditions, but you know, the answer is in the mitosis stage, Telomere sounds pretty fishy

It is really based on logic reasoning. Well, let it be Telomere or other DNA strands, whichever gets reset during the mitosis process might be the key to aging. There really shouldn't be any DNA damage on the sperm cells, if the amount of damage equals to the number of ages of a person, a damaged sperm could give rise to a 5, 10 years old, which is impossible. So somewhere along the line there should be a perfect reset, let it be lengthening the Telomere or repair the gene damages, clearly something is able to reset the damage to DNA. Short reasoning: Damage to my DNA causing me to age to 29 years old -> Create damaged DNA sperms -> Sperm give rise to 29 years old baby is clearly impossible P.S. Endy0816, you are right, Telomere does sounds like the key to aging

My speculation is following the DNA damage theory that the cell gets damaged over time as it ages. Following this theory, the sperm cell created through mitosis either does a perfect repair or the DNA damage theory is wrong in which the DNA damage is not the cause for aging and the sperm's gene expression is being reset. Again the cause for aging is still unknown, but the sperm created through mitosis cannot have defective genes P.S. Well, we've never really examined the DNA in sperm have we?

As you know, a person of age 29 should be able to create cell through meiosis that is of age 29 identical to the original cell, the cell does not become younger or older. However, sperm created through mitosis combines with egg to form a zygote of age 0. If the DNA damage theory is true that our cells DNA are damaged as we grow old, how come the sperm's DNA is not damaged, did we do a perfect repair on sperm's DNA to bring it back to age 0?

So there is a distinction, sounds great!

As much as the hype goes for crispr technique it's simply an enzyme with a molecular scissor that is able to indentify a correct strand of DNA. Now if we can replace it with nanorobotics it could do the same task with possibly higher precision. But at this stage of nanorobotics it seems we are still at an early stage, or that we can borrow the ideas from somewhere. What do you guys think and how much progress have we made on nanorobotics? P.S. You might be able to program and control the robotics wirelessly
