antimatter

Ah okay, thanks.

Right, I understand that. I asked my science teacher about it today and he said it's not as much redshift, as it's a sort of loop in time. As soon as the observer leaves the image disappears.

Ah thanks, but I have one more question. Would the traveller also stay there, frozen on the event horizon too, or just the flashing light?

Ah okay thanks, that makes more sense to me now. And so gravity causes this curve in space-time but how does that affect time?

Oh thank you! I understand now, that was very very helpful. So the time between the flashes gets redshifted until it just stops, but to the traveller (who'd most likely be dead, right?) it stays the same throughout?

You're right, I meant that in the eye of the beholder he stays frozen. I still don't really understand how redshift applies to this I understand what redshift is, it's just...well, you know.

Ah I see, I've still got a while to go. Thanks for the clarification though.

I'm not entirely sure what organs it attacks, but if you want to a read a particularily disturbing and informative book on the subject, I can recommend 'The Hot Zone' by Richard Preston. I read the book in 4th grade, and have been traumatized by it ever since.

The object becomes frozen right outside the event horizon because light can't 'refresh' the image. You already knows what happens to the object... I'm not sure if red shift has anything to do with it, but it's mostly because of gravitational lensing

Wow thanks, that was a really interesting article, I should go on the NASA website more often now, that was a great find.

We can't reach the speed of light because the amount of energy it would take is just tremendous. I am not entirely sure what you mean of how gravity warps space-time, can you explain?

Then what properties of Neutrons are changed?

For some reason when I go to the sign up page it says that "You do not have the privileges to sign up for a blog".

My opinion is that Global Warming is a very realy thing and should be taken very seriously. Al Gore, on the other hand, should not.

I think the Death Star would be a great invention, that is, in the right hands. But then again, 'right' is a relative term, some of us like the Empire, while some enjoy the freedoms of the Galactic Republic. I think that an antimatter weapon would be a brilliant invention, but so far, that's a near impossible task. Teleportation is somewhere in the near future though.

I'm antimatter, and...I like...science...?

Sorry, my mistake, I'm a little tired today.

Although this forum isn't much about opinions, I believe that the ethics of using placebo varies with the condition. If it is something minor, then it's 'okay'. In general, I don't believe that lying to your patients is all that ethical, but as DrDNA said, there are several exceptions.

The temperature in space varies with your location, for example, if you're near a star, then it will be extremely hot. On average, the temperature is generally 4 degrees above absolute zero in space.

It's just gravity. The Universe is expanding due to Dark Energy, but it's a local group of galaxies and gravity is pulling them together. The actual collison shouldn't affect us all that much, it's the gravitational pull that will throw off our Solar System.

Yes, that may be true, but I was meaning it in the sense of an increase in speed. Let's not cling to words here.

Not only is it speed, but it's also with velocity. I'm not entirely sure that accelleration can in fact slow you down. The term accelleration means an increase of speed. You are correct in what you said though.

The general idea for a functional lightsaber in the original Star Wars movies is in fact not a laser, but plasma. The plasma is held in it's form by a powerful magnetic field, because plasma is very magnetic. The answer I am giving is a no, but in the future it may be possible.

I have actually heard that there are portions of the Universe that consist of just antimatter.

I'm sure other people have given you reasonable definitions of antimatter, but a simple definition is matter that is essentially reversed. Electrons have a positive charge, thus becoming Positrons, and Protons become negatively charged. If antimatter comes into contact with any matter at all it annihilation, because the charges cancel out. Using antiparticle de-accellerators, scientists have actually been able to create anti-hydrogen using two antiparticles.
