Could there be such thing theoretically as a dark matter black hole?

If so, could we use it to travel through it to another point in space or to another universe, or go foreward and backwards in time?

What concentration of venom of Indian Cobra(naja naja) is lethal for man? How long does it take for a cobra bite to cause death? Does the cobra venom get oxidised in air? What is the time limit within which the antidote is effective? How does cobra inject venom into human body? Since it is a neurotoxic venom, how does it effect the nervous system? Are there any snake venom research centres in India/US?

At work I do stress analysis on launch vehicles. Our loads and dynamics group gives us loads (in pounds) called "Peq" or P_equivalent at various "stations" or vertical coordinates of the rocket. Most rockets, including ours, consist of a stack of lightweight hollow cylindrical structures all bolted together. The loads in these structures increase as we go down the rocket (obviously because the lower you go the more weight the structures carry along with the aero loads and pressures. My question is, what do they mean by Peq? How do they calculate these loads? I've always been curious. The loads group just keeps feeding us these numbers we plug into our models but have no idea where they come from. If anyone who does the same type of work as me could respond, that would be awesome. Thanks!

If not, what gases is it comprised. If it is, 'nature abhors a vacuum' so why does it not draw away our atmosphere? Gravity may hold most of it, but on the outer edge of the atmosphere - why not?

Also if that is possible ,could a ship cut down transit time by alternating between FTL and STL drives? I propose by alternating between these it would essentially negate time in transit.

I need the precision not the accuracy. Accuracy should be around 1 to 2 degrees C.

Identify the standard form of the equation that correctly represents each problem. (Since some solutions will be complex, you should not solve them.)

Matching:
1) The square of a number is less than the number. Find the number.

2) The product of two consecutive integers is 6. Find the numbers.

3) The area and perimeter of a rectangle are numerically equal. Find the dimensions if the length is three more than the width.
-----
a. x^2 + x + 6 = 0
b. x^2 + x - 6 = 0
c. x^2 - x - 6 = 0
d. x^2 - x + 6 = 0

Hello can anyone help me out with finding a Thermal cam for Ghost Hunting. The research we do is completely free of charge. We would like to continue completing free investigations but cannot afford this very important tool. I have been told that Fire Departments use this thermal tool and get upgraded so many years. Where does the older thermals go. Please help me out with information to who I can contact. Thanks Eric

I love electronics, but I am considering studying Electrical Engineering instead of the technology. I like working with my hands and doing projects, but at the sametime I also want to be the guy who designs the technology. I need some advice with people with industry related experience.

1.) The perimeter of a certain square is 8in. George needs to photocopy the square. He hopes to make a copy that is percisely the same size as the original. However, after making his copy, George discovers that the photocopier triples the length of every line. How many times larger than the original square is the photocopied square?
6 maybe? i dont know
