Are gamma rays the most dangerous?

Do nuclear explosions occur in space?

What is a good opening paragraph for a report about gamma rays (don't give any information just cool sayings and facts for opening paragraph)

im no brainiac, but if an estimated 96% of our universe is dark, or unaccounted for, why would anyone think they could account for it?

How can science say, on one hand, "density or gravity can be so intense that it can bend light, and bend time" and on the other hand legitimately agree on and publish a size and age of the universe?

thats like me saying "it might rain in new jersey january 24, the year 5000" and then i prove it. i dont get it

as untrustable / idiots / brainless that carries with them from answer to answer?
So that way we (the people who ask questions) can more readily set a limit of the credibility to those that answer our questions.
I am so tired of the 'copy and pasters' wikipedia quoters who think that wikipedia is the only credible source of info (it's not. its rife with errors and opinion)
And the schmucks with persistent dumb off topic or completely brainless responses.

Tell me a little bit about gamma rays including frequency, wavelength, ect. What would be a good opening sentence for a report about gamma rays?...Something that would sound good and catch peoples attention.

Was the Big Bang just a single explosion of a repeatative process? Does the universe expand and contract in rythem, much like that seen within energy waves or atomic organization. Pulling itself into a singularity and exploding over and over again, perhaps forever?

Is it just like one giant perpetual energy machine? If that's possible, wouldn't light given off at the edge of the universe be lost as total energy, causing an eventual breakdown of the system, or is the universe supposed to just expand forever?

If it's possible that it will expand forever, what were the factors that had to already be in existance that caused this reaction? Is it possible that the universe is only one of many within a multiverse?

Perhaps our galaxies and our universe composes the "fundemental" building blocks (the quarks and atoms so to speak) of another level of existance.

Is it possible that if we keep breaking down energy into smaller forms we'll eventuall stumble upon our own existance?

Suppose that Earth grew to its present size in 1 million years through the accretion of particles averaging 100g each. On the average, how many particles did Earth capture per second?

Hint* Appendix A will tell you the Earth's mass.

If we would meet one, it could look totally different from us or quite the same. If the big bang theory is true, then won't the aliens have DNA like us and possibly look like us? Thanks for answering!
