Astro-physics

Seriously, modern physics and astronomical sciences hurt my brain. Here are four reasons why.

Time travel could be real, involve portals

Excerpt:

Einstein’s theory’s of relativity only precludes travel at the speed of light, he never said anything about travel faster than light. Of course it will still take an incredible amount of energy, but crucially not an infinite amount.

Now it turns out that a little technique called quantum tunneling is used by electrons orbiting around atoms to instantly move from point A to point B without passing through the space in between.

If we could utilize a similar process and "quantum tunnel" through the barrier of the speed of light, we might just be able to travel faster than light, but never actually have to travel at the speed of light to get there.

It only looks like gravity smashed your face into that sidewalk

Excerpt:

“For me gravity doesn’t exist,” said Dr. Verlinde, who was recently in the United States to explain himself. Not that he can’t fall down, but Dr. Verlinde is among a number of physicists who say that science has been looking at gravity the wrong way and that there is something more basic, from which gravity “emerges,” the way stock markets emerge from the collective behavior of individual investors or that elasticity emerges from the mechanics of atoms.

Afraid of an asteroid strike? That's small potatoes

Excerpt:

Astronomers using NASA's Hubble Space Telescope have detected a blue star called HE 0437-5439 they say was unceremoniously expelled from the Milky Way and is now hurtling through space at 1.6 million miles an hour. Scientists say his rates as one of the fastest of the 16 so-called hypervelocity stars they've discovered since 2005.

Aliens probably use text message acronyms, too

Excerpt:

''Whatever the life form, evolution selects for economy of resources,'' said Gregory Benford. ''Broadcasting is expensive, and transmitting signals across light years would require considerable resources.''

Writing in the journal Astrobiology, the Benfords claim that an alien civilisation would strive to reduce costs, limit waste and make its signalling technology efficient.
