How About That?
Curiosity
What would a planet orbiting a pulsar look like from the ground? Would it look like a giant disco planet with a constant strobe light? Pulsar form from supernova explosions, and they are neutron stars that spin on their axis thousand time per second.
Astronomy
I know that likelihood of stars colliding is very low, but have there been papers describing the theoretical process of star collision? James, London I think we can divide star-collision into three classes; Stellar Mergers, Binary Collisions and Stellar Collision.
Asteroid
What does it actually look like in the asteroid belt? Is it anything like as dense as is shown in films? Or is it more like you can see one or two rocks in the distance? Contrary to popular belief, the asteroid belt is mostly empty.
Andromeda
If by big we mean physical dimension, the largest known galaxy is most likely IC1101. IC1101 is gargantuan even among galaxies; it’s a super elliptical galaxy with a diffuse stellar halo that to extends to at least 1.4 million light years. The Milky Way’s halo by comparison extends to about 100.0...
How About That?
For all intents and purposes gravity travels at the speed of light but it is very hard to measure, and so far we have no direct model-independent measurement of the speed of gravity. Physics has to main gravitational models: Newtonian dynamics and General Relativity The Newtonian gravitational mo...
Dark Energy
If the universe continues expanding forever, how long until it’s too diffused to allow star formation? How many generations of stars will that mean the universe has? How will the elemental make-up of these late stars be different and what effects will that have?
Big Bang
If the 1st Law of Thermodynamics is true how could the Universe begin from nothing? To answer this question we need to remember that nothing is a global term and not a local one.
Drake Equations
Assuming that there are other intelligent civilisations out there in the universe, what is the likelihood that we’ll ever be able to communicate? The key to answer this question is to look at the Drake Equation.
Antimatter
Dear Mr Science Guy, How many calories would get in a bottle of antimatter? How long would it take to burn off at the gym if you drank it? Thank you, Rob, age 30 Rob asks a very interesting question which allows me to explain several different concepts. First of all, what is anti-matter?
How About That?
Last night I had a nightmare that the centre of London was nuked. In my half-sleep state I tried working out if I could survive just by getting under my mattress or if I had to get out of bed to be more proactive for my survival. First, I had to check what kind of […]
