I do crunch Einstein from time to time, and as I haven't looked in on the science results for a while, have any gravity waves been detected? A detection of a wave would eliminate the possibility of an instantaneous gravity field that moves with the mass as one object.

When the Earth was formed the gravitational field started to spread with the speed of light. That was about 4 billion years ago so that field is now 8 billion lightyears across.


That is one thing I have always wondered about. I always assumed that gravity propagated at the speed of light, but that has never been measured. gravity has not actually been defined properly, even though we can work with it mathematically to great accuracy. I wonder if it really does propagate at the speed of light, or is an intrinsic property of mass, moving as the mass moves. I really don't know.

I realize that the white hole idea is not new. I guess it is like the quantum world. The actual reality doesn't make a lot of sense. Entanglement, the two slit experiment, and objects passing through each other given enough time are great examples. It is much easier to think about something that seems to make sense, than something that defies every attempt to assign sense to it. I am really hoping that we will learn what dark matter and dark energy actually are at some point. They may or may not shed some more light on the good old black hole....

That is a tough one. The known math kind of crumbles at that point, but clearly there are black holes of different strengths. That would imply to me that matter is inside a black hole, but not in a form we are used to. I keep thinking, perhaps incorrectly, of a singularity of mass. We are used to elementary particles, but if you remove all distance between those particles, you end up with one particle of no elementary particles, no quarks, bosuns, or strings, just pure mass. Since most if not all galaxies have at least one super massive black holes in their centers, and one was recently identified as having the mass of a trillion suns, I wonder if there is a size limit. I may be wrong again, but if there is a size limit, it might explain our present universe, as the result of the gravity of a supper, supper, supper massive black hole, collapsing in on itself, and immediately transforming into pure energy via E = MC^2. That doesn't explain inflation, but the temperatures were so great there must have been unknowns yet to be quantified.

There is a difference between mass and matter.
Matter is easy to understand but mass...
As energy and mass are convertable so what's the problem with that matter "disappears" and warps space and time?

What is the difference between matter" and "mass"?"
Matter is anything that takes up space, can be perceived by your senses in some way, and has mass. In other words, matter is what a makes up a hot dog, a scooter, an elephant — any material item you can think of.


I wasn't aware that they were separable. I have read that a black hole does have size, depending on the mass. In my mind that single particle would have a size greater than zero. If I am wrong, and a black hole truly has zero size, then that is really mind bending, as the event horizon is at different distances from the center depending on the mass of the black hole. As I said, I am just speculating, using my current knowledge as a basis, and may be completely wrong. It makes for some fascinating thinking though.

Just speculation on my part, and may be completely wrong.

Philae comet could be home to alien life, say scientists

The comet landed on by the spacecraft Philae could well be home to an abundance of alien microbial life, according to leading astronomers.

Features of the comet, named 67P/Churyumov-Gerasimenko, such as its organic-rich black crust, are most likely explained by the presence of living organisms beneath an icy surface, the scientists have said.

http://www.theguardian.com/science/2015/jul/06/philae-comet-could-be-home-to-alien-life-say-top-scientists

So, where did life really begin? We will probably never know.

I would guess, that it originated in many different places, perhaps in many different ways. We are familiar with carbon based, but that may not be the only possibility. At least we know that carbon based does work.

For this instance, scientists said that Rosetta and Philae really don't have the instruments to determine one way or the other. So the initial report has not passed scrutiny.

Posted 3 Jul 2015 by Profile SciManStevProject donor
I would think that an intelligent being could be any of many forms, but with, or without the advantage of being able to manipulate their environment. We have hands, octopi have arms and suction cups. On the other hand, dolphins have sonar. Dolphins and whales are quite intelligent, but are adapted for their environment. With the advantage of hands, humans were able to adapt themselves to various environments. I am not sure we could ever classify what an intelligent being would look like, without actually seeing one or more. There may be countless possibilities that could evolve, depending on unique environmental conditions.

I think that it is fair to say that in the near future we can put this "We have been visited "stuff to rest. If we haven't already; we will soon have searched for truly Earth-like planets around all stars out to 100 light years as well as promising moons. If there are in fact any "Habitable" planets that we find we can then concentrate our SETI efforts on these ones.

We will probably not find other venues at these distances with all of the necessary conditions for intelligent life to form. If we do; we won't detect any transmissions or other signs of life if they are not intentionally sending out a focused "we are here" message. if they are then we would have heard them by now.

Speculating that multi-decade trips have been undertaken from these distances and beyond just doesn't make good sense.

To support the notion that life will spontaneously arise in a fertile environment then we desperately need to confirm life on Mars. Either microbial or plant life--perhaps now long extinct.

I completely agree with this. I would add that there is also great interest in Europa due the the probability of a "below the surface" liquid water ocean.

It would not be unreasonable to speculate that microbial or more advanced life could be living in those ocean(s).

In actuality, building 7 was just physics. Each deck that collapsed added weight, and inertia to the moving system, and the support beams couldn't handle it.

Seems like it takes an awful lot, in a small area to just melt a car. Any Thermite paint would have had to been applied at the construction, and be almost a foot think.

For, me, I know the future doesn't go backwards. I am also looking forward to that holographic headset, if they get it perfected. I realize that it works now, but the field of view is very small. I am mentally ready to move forward, both with Windows 10, and new hardware. This old CPU 950, and GTX 480's system is ready for a massive upgrade. I have always wanted the most powerful computer I could build, even long before there ever was a Seti@home. Some people like fast cars, fast motorcycles, and fast women, but I like fast computers.....

Well, fast women aren't to bad either.

After reading these posts, I think I know what I am going to do. I had intended to build a new version of my computer, Piggy. I am saving money for it on one of my credit cards. Intel will be coming out with a new CPU in 2016, which looks very good. I know I am going to make that build with Windows 10. Since I installed my Samsung 850 PRO 1 TB SSD a few months ago, I didn't install everything I wanted, because I knew Windows 10 was coming out.

Since I am not ready financially yet to rebuild Piggy, and the new CPU is still slated for next year, I will go ahead and give the free Windows 10 a spin on my current system. I will just buy the $150 version to be ready for when the new CPU is ready. It is an 8 core extreme version, and I intend to push it very hard. After I finish the build, which will be a new CPU, new motherboard, and new RAM with my existing 1 TB SSD with a clean install of Windows 10, I will spend the time tweaking it for maximum potential. Then, I will look into upgrading my old GTX 480 GPU's. I will water cool the new GPU's also, and start maxing them out.

This way, the freeby Win 10 is nice, and I get experience with it before diving into a new build.

That is the very reason I will just buy a copy. I would hate to reinstall Win 7, just to reload Win 10. I still don't know if it will end up being a service or not.

I am looking forward to Windows 10, except for one thing. I will lose control of updates, which can force reboots at a bad time. As I am a software engineer, I create tests that can take over a week to complete. An unscheduled reboot could cost a week of testing.
