Are Black Holes Really 2D Holograms and Other Future Tech
Today, we’re going to start off with a question that has
intrigued physicists across the world – where does stuff go when it enters a
black hole?
Are Black Holes
Really 2D Holograms
We all know that information that even light cannot escape a
black hole. But, what does that mean for the law of conservation of energy.
Actually, renowned theoretical physicist Prof Stephen Hawking proposed in 2015
that black holes might be 2D holograms of information.
“The information is not stored in the interior of the black
hole as one might expect, but in its boundary – the event horizon. The idea is
the super translations are a hologram of the ingoing particles”, said Prof
Hawking. Thus they contain all the information that would otherwise be lost.
This information is emitted in the quantum fluctuations that black holes
produce, albeit in chaotic, useless form. For all practical purposes the
information is lost.”
But wait! Alternate histories in black holes? “The existence
of alternative histories with black holes suggests this might be possible. The
hole would need to be large and if it was rotating it might have a passage to
another Universe. But you couldn’t come back to our Universe. So although I’m
keen on space flight, I’m not going to try that,” he added. Interesting theory,
indeed!
New Brain Cancer
Treatment Leads to Cure in Trails
One of the toughest nuts to crack is brain cancer, due to
the fact that even a miniscule amount damage has the potential to end lives.
But now, thanks to medical technology, researchers have engineered a new type
of viral treatment that shows a survival time of 13.6 months for patients
suffering from Glioblastomas. This is huge when compared to the survival time
of patients who didn’t receive the treatment. Some patients lived upto more
than 2 years without many side effects.
First, the patient is given an injection with Toca 511 - a
virus that delivers an enzyme called cytosine deaminase (CD). This spreads
throughout the tumor and that converts Toca FC (an oral antifungal drug) into 5-fluorouracil,
an FDA-approved anticancer drug.
"For the first time, this clinical data shows that this
treatment, used in combination with an antifungal drug, kills cancer cells and
appears to activate the immune system against them while sparing healthy
cells," said Dr. Timothy Cloughesy, Director of the Neuro-Oncology at the University
of California, Los Angeles and Consultant for Tocagen – the biopharmaceutical that
developed and funded most of the research.
